I'm now pleased to introduce the Chairman and Chief Executive Officer of PerkinElmer, Rob Friel. Rob?
Robert F. Friel - Chairman, CEO and President
Thanks, Tommy. Good afternoon, and thank you for joining us today. I'm pleased to report on PerkinElmer's strong start to the year in which we delivered a solid financial performance and made good progress on accelerating our long-term profitable growth.
Through the first 3 months of this year, I'm encouraged by the progress we're making to further differentiate our capabilities by introducing innovative new products while also improving how we provide a better and more complete customer experience. Andy will cover our financial performance in detail. But at a high level, we exceeded our revenue and profitability expectations as organic revenue grew by 4% during the first quarter and adjusted earnings per share increased 10% to $0.55.
As you recall, at the end of the third quarter of last year, we announced the realignment of the company into our 2 business segments of Diagnostics and Discovery & Analytical Solutions, or DAS. The intention was to better position PerkinElmer to more effectively serve and innovate for our customers. Now 6 months into the reorganization, we are pleased with the number of improvements we've made from a leadership, process and capability standpoint. R&D teams are coming together to drive more targeted and collaborative innovation, and the new united -- unified front-end sales and service teams are actively selling complete solutions across the portfolio to holistically meet customer needs, an important differentiator for PerkinElmer.
Specifically in the Diagnostics business, we are working to increase our leadership positions in the key growth areas of reproductive health, infectious disease and oncology. During the first quarter, we launched 2 new products to facilitate targeted sequencing and detection of genetic variance to aid in oncology and genomics research. In particular, using amplicon studio, we continue to release new sequencing panels for our customers on a catalog and customer basis -- and custom basis. And our new NEXTflex control system helps detect contamination as well as human and sequencing process errors.
We also announced a relationship with 10x Genomics to combine our high throughput automation platform to create a compelling workflow for long-range structural cellular information.
In the area of infectious disease testing, we closed our acquisition of Tulip Diagnostics in India at the start of the year, and integration is well underway. Tulip brings a strong product portfolio, channel access and broad footprint that will help accelerate PerkinElmer's growth in this important market.
In China, we continue to expand our infectious disease menu. And during the first quarter, we introduced a new assay for hepatitis B surface antigen and a PCR-based hepatitis C assay kit.
Within reproductive health, we expanded newborn screening programs in the first quarter, particularly in emerging markets. In China, greater penetration of mass spec and the increasing adoption of our automated GSP screening solution is enabling expansion of the menu of tests administered to newborns. In India, where newborn screening occurs less than 5% of the time, we continue to make progress on expanding pilot programs. In addition, we are seeing strong interest from private sector commercial diagnostic labs in offering our screening technology, potentially accelerating our penetration of this significant opportunity.
Additionally, we continue to be excited about our Vanadis smart NIPT technology currently in development. The program reached key milestones in the first quarter as we have now automated an assay that very accurately measures trisomy 13, 18 and 21. We remain on track to introduce instrumentation to beta customers in the second half of this year, with CE IVD approval expected in the first half of 2018. To reiterate, this new offering will allow maternal fetal health labs to use a high throughput approach with lower labor requirements, enabling millions of pregnant women access to affordable, noninvasive prenatal screening.
Another potential growth driver to our reproductive health business is a recent Phase I clinical trial conducted by Duke University, evaluating the use of a baby's own cord blood stem cells to treat autism spectrum disorder. We are proud that ViaCord, our cord blood and cord tissue preservation business, provided nearly 1/2 of the banked cord blood units used by the families participating in this important study. We are optimistic that the positive result to this trial will expand the potential uses of family cord blood banking by highlighting the opportunity for its use in regenerative medicine, including autism.
In the DAS business, we are optimizing our commercial, operational and R&D capabilities to pivot the business to deliver higher growth and better weather varied economic conditions. For this year, the key priorities are launching several exciting new products in our focused areas of growth and better leveraging our 1,700 service engineers and informatics capabilities to strengthen our position as a strategic partner for our customers.
Regarding new products, during the first quarter, we introduced the Nexion 2000 ICP-MS. Capable of handling any sample metrics -- matrix, the Nexion 2000 can be configured to provide results for many critical applications, including analysis of trace elements in environmental and food samples or testing for elemental contaminants in pharmaceutical products. Nexion is also opening up new products such as fast, accurate nanoparticle characterization and even single-cell applications. The Nexion 2000 allows scientists to study the cellular uptake of heteroatom-containing drugs, thereby better understanding their efficacy in vivo.
During the quarter, we also introduced the Vectra Polaris, part of our Phenoptics portfolio solution for quantitative pathology. This new tissue-imaging system enables researchers to gain a deeper level of understanding of potential cancer immunotherapies.
Also during the quarter, we continue to experience strong demand for several of our products introduced in the back half of last year, including our new QSight triple-quad mass spec as well as the Operetta CLS.
In addition to driving our organic growth rate, these 4 recently introduced products expand our addressable markets by several hundred million dollars in attractive growth areas.
Over the last several quarters, we have been investing significant energy and resources in improving our processes and capabilities regarding new product development and commercialization. Our progress over the 2 last quarters is encouraging, and we remain confident in our goal of adding $50 million of incremental revenue this year from new product introductions.
Our DAS service business, which is now unified under the OneSource brand, is approaching $600 million in annual revenue and has built a strong market position in managing the laboratory assets of our customers, particularly in the pharma, biotech space. More recently, we've been using this extensive presence in the labs to better understand the workflow of our customers and look for what we refer to as asset adjacencies. By changing the dialogue to broader workflows as compared to only instruments, we change the discussion about one -- from one about asset optimization and cost to one about business outcomes and improved results. Consequently, conversations with customers become more strategic, which both expands the market potential and the opportunity to provide more value-added services.
From an organic perspective, we see significant opportunity to increase growth through focused innovation and by enhancing the customer experience.
Looking at our end markets, conditions are playing out fairly consistent with what we expected when we prepared our plan for this year. We continue to see strength in all 4 of our key focus areas comprised of reproductive health, emerging market diagnostics, food and biopharma services. In the first quarter, these areas grew high single digits for us and now represent just under half of our total revenues, up from roughly 40% 2 years ago. Our core businesses serving the industrial, drug discovery and environmental markets comprised the remainder of revenues in the quarter and saw a flat but stabilizing demand.
In addition to organic growth expansion, we are also pursuing several opportunities to better focus our portfolio through selective divestitures as well as acquisitions in our targeted areas of growth. Earlier this week, we closed the sale of our medical imaging business, resulting in proceeds of roughly $270 million. Consistent with our statements made in the beginning of the year, our intention is to deploy this capital to expand our capabilities through acquisitions or to buy back shares. Once we have deployed the capital, we will provide specific details on the use of the funds.
So to summarize our first quarter, I would say we delivered a solid financial performance, exceeding our commitments on the top and bottom line. We made good progress on new products and organizational alignment to growth priorities. Market conditions have been consistent with our planning assumptions with a little less foreign exchange headwind. And we are excited about having a robust pipeline of potential acquisition opportunities.
I feel we're in excellent shape and are quite confident we will make real progress this year increasing our long-term growth trajectory.
I would now like to turn the call over to Andy to discuss our quarterly financial results in more detail. Andy?
Frank A. Wilson - CFO and SVP
Thanks, Rob, and good afternoon, everyone. Consistent with previous quarters, I'll provide some additional color on our end markets, financial summary of our first quarter results as well as details around our guidance for the second quarter.
It was a solid start to the year, as reported revenues from continuing operations were $514 million, resulting in organic revenue growth of just over 4%. FX negatively impacted revenue growth by approximately 1% and the net impact of acquisitions and divestitures in the quarter was approximately 50 basis points.
New product introductions within our Discovery & Analytical Solutions business, coupled with solid execution, helped to drive the revenue beat in the quarter. As Rob mentioned, we are reiterating our expectation for approximately $50 million in incremental revenues from new products for this year.
Adjusted earnings per share from continuing operations for the first quarter grew 10% to $0.55 from $0.50 in the comparable period a year ago, a result of higher revenues, partially offset by incremental R&D spend in the quarter.
Looking at our business segments and served end markets. Diagnostics organic revenues grew 8% organically in the first quarter, with healthy demand in reproductive health, infectious disease and oncology. DAS grew 2% organically with environmental up high single digits, food and pharma biotech up mid-single digits, industrial was flat but improving sequentially and academic and government declined low single digits.
As we exit the first quarter, we think most of our end markets, as Rob mentioned, are playing out as expected with the academic end market continuing to underperform.
Looking at our geographic results for the first quarter. We experienced high-teens organic revenue growth in Asia, low single-digit organic revenue growth in Europe and low single-digit declines in the Americas. In the BRIC regions, organic revenue growth was broad based with an overall increase of more than 20%.
As to our operating results, first quarter adjusted operating margins from continuing operations of 16.3% came in as expected, as we increased R&D spending in the quarter by 50 basis points due to accelerated investments in both Diagnostics and DAS, while adjusted SG&A improved by 100 basis points driven by the success of ongoing indirect spend initiatives. Adjusted gross margins were down versus the prior year due in part to the impact of acquisitions and divestitures consummated in 2016, which represented a 40 basis point headwind as well as a mix shift in the laboratory services. The headwinds related to the aforementioned acquisitions and divestitures are not expected to continue as they anniversary early in the second quarter.
By segment, adjusted operating margins for DAS were 14.1%, down 100 basis points from the prior year due primarily to incremental investments shifted into the first quarter as well as a very difficult prior year comparison. Adjusted operating margins in our Diagnostics business improved 160 basis points over the same period last year, the result of strong revenue growth and a positive mix of reagents. For the full year, we believe DAS operating margins will expand 80 to 100 basis points, with Diagnostics operating margins expanding more modestly due to investments slated for the balance of the year. Netting it all out, we remain on track to deliver on our full year gross and operating margin expansion commitments.
Looking further into our reporting segments for the first quarter, Diagnostics, which represents approximately 30% of total revenue, had strong results as compared to the same period a year ago. Growth was driven by continued strength within our core reproductive health franchise, which grew high single-digits organically, led by double-digit newborn screening growth. We continue to experience strong revenue growth outside of the U.S., and we believe that the opportunity to further penetrate emerging markets remains promising.
Growth in our infectious disease product offering experienced high single-digit organic revenue growth driven by SYM-BIO and our Chinese clinical lab, which has been operational for a little over a year.
Finally, our oncology offering, focused predominantly on NGS workflow, saw a mid-single-digit revenue growth driven by demand in Europe and Asia.
Switching to our Discovery & Analytical Solutions business, our improved performance was driven by solid execution on our go-to-market applications-focused strategy as well as early traction from our new product introductions.
In terms of drivers behind our growth by end market, growth was driven in part by our new ICP-MS offering targeting environmental applications, while pharma, biotech strength was driven by another very strong performance from OneSource, which was up mid-teens in the quarter. We remain pleased with the success of the OneSource team and believe that our differentiated service offerings continue to provide unique insights for pharma and biotech customers around the world.
Food revenues grew organically mid-single digits in the quarter in spite of a very difficult comparison in the prior year. Organic strength was driven by double-digit growth in Perten, and their results strengthen our belief that nascent secular trends for grain moisture and protein analysis continue to improve.
Industrial revenues were flat with modest order improvement while academic and government results remain soft.
Overall, we feel good about our revenue performance in the first quarter and remain hopeful that recent industrial trends and this week's announcement to fund the NIH will help improve organic revenue growth in the second half of 2017.
In terms of operating margin expansion, as I mentioned, we're confident in our ability to deliver 70 to 90 basis points for the year as Lean initiatives continue to ramp and we continue to benefit from low-cost sourcing actions.
First quarter net interest and other expense was approximately $11.6 million and our adjusted tax rate was approximately 17.5%, essentially in line with our guidance of 18%.
Turning to the balance sheet. We finished the quarter with approximately $1.1 billion of debt and nearly $290 million of cash. We exited the quarter with a net debt to adjusted EBITDA ratio of approximately 1.7x.
Turning to cash flow. We had a good start to the year with operating cash flow from continuing operations of $41 million as compared to $26 million in the first quarter of 2016. This performance was due in part to successful working capital initiatives, focused on receivables and inventory, which contributed to an improvement of 2 and 14 days, respectively, versus the first quarter of last year.
As we look ahead to the balance of 2017 and beyond, we believe that we can continue to more efficiently manage our working capital needs through the expanded use of Lean tools.
Looking into the balance of 2017, we believe we are well positioned to deliver solid financial performance and see a path to improving organic growth driven by new product introductions and more favorable year-over-year comparisons.
As a result of more favorable foreign exchange headwinds and better revenue growth in Q1, we are raising our reported revenue guidance for the full year 2017 to be in a range of $2.2 billion to $2.22 billion. This continues to represent organic revenue growth of 4%, which now includes $25 million to $30 million in foreign exchange headwind and approximately $30 million of revenue from Tulip, our recently acquired Indian diagnostics company.
In addition, we are raising our guidance for the full year adjusted earnings per share from continuing operations to reflect our Q1 results and updated foreign exchange impact from a previous range of $2.75 to $2.85 to a new range of $2.80 to $2.90, which does not incorporate any impact from future capital deployment.
For the second quarter of 2017, we are forecasting reported revenues to be in the range of $550 million to $555 million, which represents organic revenue growth of approximately 3% to 4% with FX representing a headwind of approximately 2%, which is offset by the impact of our recent acquisitions.
As a reminder, Diagnostics in the Asia Pacific region have very difficult Q2 2016 comparisons. We remain cautious but optimistic that the industrial and academic end markets within DAS will pick up in the second half of 2017.
In our second quarter guidance, we are assuming $12.5 million of net interest and other expense and a weighted average share count of approximately 110 million shares. As a result, we expect second quarter 2017 adjusted earnings per share to be in the range of $0.66 to $0.68.
This concludes my prepared remarks. Belinda, at this time, we would like to open up the call to questions.
Operator
(Operator Instructions) And our first question comes from the line of Tycho Peterson from JPMorgan.
Steven Paul Reiman - Analyst
This is Steve Reiman on for Tycho. I guess, just first off, so it sounds like you expect DAS organic revenue to improve in the back half of the year. Can you talk about how much of that is dependent on improving end-market growth versus new product flow?
Frank A. Wilson - CFO and SVP
I think we are not considering any huge step-up in end markets, although we were encouraged by the improvement that we saw through the first quarter in industrial end markets. I would say, really, the majority of that growth is coming from new product introductions. We launched several in the first quarter. There's a number in the second quarter as well. Those will continue to ramp in the year. And we also have an easier comparison in the second half as well, which will obviously be beneficial for the organic revenue growth.
Steven Paul Reiman - Analyst
Got it. And then you mentioned growth in the BRICS was broad based. So does that imply you're seeing some improving conditions in Brazil and Russia? And could that potentially be a source of upside this year?
Frank A. Wilson - CFO and SVP
Yes. We are. I mean, obviously, last year, both economically and due to the issues with the Zika virus, we didn't see a significant headwind. Obviously, we have a much lower bar, but we did see growth in the first quarter and we are expecting growth through the balance of this year, although off of again a more modest base.
Operator
And our next question comes from the line of Dan Arias from Citigroup.
Daniel Anthony Arias - VP and Senior Analyst
Rob, not sure if it's difficult to quantify, but any way you can kind of parse out how much of the better organic versus the guide was from better execution in the selling processes that you've mentioned versus end markets? I mean, it sounds like it was almost all the former, but just want to make sure I'm seeing it right there.
Robert F. Friel - Chairman, CEO and President
Yes. I would say, going back to Andy's comments, I mean, we're not seeing a dramatic change in the end markets relative to what we thought sort of in the December-January time frame. So I would say, the improvement, it was largely on the DAS side -- really came from better execution, particularly on the service side. So very strong service growth in the first quarter. I mean, I think the products also benefited from the new products, but I think it was more execution than market.
Daniel Anthony Arias - VP and Senior Analyst
Okay. And then maybe, Andy, if I just go back to what you said about the outlook. On the new product side with the ICP-MS platform, not to get too granular there with how you're thinking about the ramp and the contributions, but I'm just kind of curious whether when you gave your outlook for new products, do they contemplate a product launch into some sluggish environmental, industrial markets? Or were you kind of thinking implicitly there that there should be some pickup in demand by the end of the year? And I know you're highlighting some of the research functions there, but maybe on the industrial side -- basically, is there a couple of billion of upside there?
Frank A. Wilson - CFO and SVP
Yes. I would say that as we were going into the year and we were looking at what we thought we could get from the launch of the new ICP-MS, we were assuming a bit more sluggish industrial market. So I think if we continue to see improvement in industrial, I think we'll see a bit of a pickup. It's hard to quantify what that might be, but it certainly will be a net positive.
Operator
And our next question comes from the line of Steve Beuchaw from Morgan Stanley.
Stephen Christopher Beuchaw - Equity Analyst
I'd like to jump off the comments around the efforts to restructure the commercial organization. It was an important point, as you guys framed up, the growth in the second half last year that we were going through a transition there. Now that you've seen some of the benefits of those efforts, could you give us a sense, just to layer on top of the commentary you've given us so far, what inning do you think that we're in, in terms of the benefit from those changes?
Robert F. Friel - Chairman, CEO and President
I would say it's fairly early. As you pointed out, Steve, we're encouraged by the progress we saw in the first quarter, but it's still pretty early. We've got 2 fairly large organizations coming together. And we had to standardize some processes, even some compensation arrangements and obviously, leadership. But I would say the areas where I think we're really seeing some early wins is clearly in the service organization. I alluded to the fact we saw nice growth there. We're seeing significant benefits from the global account program that we have. So we've got some 12 or so global accounts that are now able to sell sort of all the products of PerkinElmer across the old historical environmental and life science business. So I would say some early wins, some early good indications but it's fairly early days. I would say -- I know you asked the question on the front end but also I would say, the other area we're seeing is on the R&D. I mean, clearly by consolidating the R&D across the larger DAS organization, we're seeing some benefits there in the pace and commercialization of the new products.
Stephen Christopher Beuchaw - Equity Analyst
I appreciate all the color there, Rob. I guess, just to follow up on that. Taking into consideration the comments on some of the encouraging signs in industrial, the traction and the momentum you have there on the commercial organization, and easy comps in the back half of the year, it's a little tricky to look at a model and say that the full year comes in around 4%. The pattern seems to be shaping up a little bit better than that. Are there any items you might flag for us that should keep us conservative when the trend looks to be a little bit stronger than that 4%?
Robert F. Friel - Chairman, CEO and President
I would say no. I don't know that there's any strong indicators that would suggest that we're concerned other than it's early. I think Andy pointed out that in Q2, we are bumping up against both difficult comps in Asia -- in APAC as well as Diagnostics. So obviously, that's something that concerns us a little bit in Q2. So I think the 3% to 4% guidance is prudent. But I think if we continue to see the markets that we've seen through 4 months, and we continue to make the good traction in the new products, I would expect there'd be an opportunity to maybe do better than the 4%.
Operator
And our next question comes from the line of Ross Muken from Evercore ISI.
Ross Jordan Muken - Senior MD, Head of Healthcare Services and Technology and Fundamental Research Analyst
Maybe can you just give us a little bit of color on some of the pharma end markets and sort of what you saw there and maybe cut it by customer type and geography, in case you saw anything that was sort of notable. It seems like Asia and China in particular on the pharma side has been a pretty big strength across most of the quarters.
Robert F. Friel - Chairman, CEO and President
Yes. So we saw a pretty good strength in pharma. For us, it was sort of mid-single. And of course, when you look at the split of our businesses, we've got a little bit of headwind with the radioactive. So when you're sort of excluding that out, we were probably in sort of the high single digits. When you look across the sort of geographies, clearly, it was APAC that was a significant driver of that. We saw very strong growth in APAC, driven largely by China. And -- but we continue to grow both in the Americas and in Europe, but something more in the low single digits. So again, much more Asia driven, much more sort of imaging. Our imaging products, our reagent products are really the driver. And of course, the services I alluded to were the big drivers to our -- of our pharma strength. But pretty strong and pretty broad based.
Ross Jordan Muken - Senior MD, Head of Healthcare Services and Technology and Fundamental Research Analyst
And maybe just on the M&A front. You have a lot of capacity. Obviously, you said if you can't do anything, you'll do repo. But you did tuck in Tulip. There's a pretty active market we've seen just in general. How would you kind of characterize the pipeline? What are the types of assets or the spectrum of stuff you're sort of thinking about more from a high-level perspective would be sort of helpful.
Robert F. Friel - Chairman, CEO and President
Yes. So as I mentioned, we've got a pretty good pipeline. We feel fairly confident we'll get some stuff done here in the latter part of '17. The focus areas are the ones we've identified. So it's going to be diagnostics. It's going to be food. It's going to be pharma services. It's going to be those critical areas where we see both a combination of our core capabilities with strong differentiation as well as the overarching growth prospects of those businesses and markets. So those would be the area of focus. Historically, we've had a tendency to do smaller bolt-on deals, and probably those are the majority of the ones that are in the pipeline. As I've said on a number of occasions, I'd like to expand that. And as much work goes into a $50 million deal as it does to a couple hundred million dollar deal, so if we could do something a little larger, that would be great. But -- so it's in that sort of range from a revenue perspective, right, things that are probably in the tens of millions to maybe a couple that are actually larger than that.
Operator
And our next question comes from the line of Isaac Ro from Goldman Sachs.
Isaac Ro - VP
A question for you on China newborn. You mentioned in your early prepared comments that penetration of the mass spec option had really picked up. Just curious if you could give us a ballpark in terms of where you are in driving that market kind of up-sell. And if I recall, the economics there are significantly better. So I'm just interested in where that can go over the next, let's say, 24 months?
Robert F. Friel - Chairman, CEO and President
Yes. And so I would say right now, if you look at China newborn, we think there's about 90% penetration of screening. But as we've talked about in the past, it's generally depending on the part of the country, it's in the 2 to 4 [disorders]. We've seen a fairly good ramp-up of mass spec. We think that's probably more in the 20% to 25% penetration now. And of course, the benefit of mass spec, you get an additional sort of 15 to 20 tests that you can do with the same sample. So that's where we think the penetration is. On birthrates, it's been sort of low single digits, as I think we've talked about in the beginning of the year. We knew we'd come off a very strong '16. So when Andy talks about the strong growth in newborn, it's really coming from menu expansion and, to a large extent, it's the expansion of mass spec penetration. And then I also alluded to the fact that we're seeing good uptake of the GSP, which is the automated platform. So penetration now at 90%. Birthrates are sort of moderating in the low single digits. It's really coming from menu expansion.
Isaac Ro - VP
Got it. And then just a follow-up on capital deployment. You guys have obviously been very proactive in reshaping the portfolio with the medical imaging divestiture. And at the same time, you've been pretty disciplined about acquisitions just given how expensive assets are. So if you had to probability weight the likelihood that something may be bigger than Tulip, something more significant on the earnings side comes through in the next, let's say, 6 to 12 months, is that a decent possibility, low possibility? Just kind of curious...
Robert F. Friel - Chairman, CEO and President
Yes. As you know, it's tough to put probabilities on these, right? Because there's a lot of things that can sort of cause problems. But I think we feel pretty good about the probability of getting something done here in the next 3 to 6 months.
Operator
And our next question comes from the line of Doug Schenkel from Cowen and Company.
Douglas Anthony Schenkel - MD and Senior Research Analyst
I think I only have 2 or 3 quick ones. The first one on -- another follow-up on newborn screening. You mentioned the opportunity in your prepared remarks to expand newborn screening in other emerging markets beyond China. How would you describe the stage of your commercial and broader infrastructure to fully go after that opportunity? The second question is on the academic government end market. I think you indicated that there was some softness in the quarter. Would you be willing to provide a little more detail on which geographies were weaker than expected? And my last question is just in the context of guidance, my impression was coming into the year that you've acknowledged you were somewhat dependent on the industrial end market improving to get to your guidance. You sounded pretty positive on how industrial was trending during the quarter. But it sounds like maybe you're a little less dependent on industrial improving to actually get to your goals for the year. Is that the right way to think about things? I will stop there and get back in the queue.
Robert F. Friel - Chairman, CEO and President
Okay, great. So as far as commercialization in newborn, I think we're in very good position there. We've been operating internationally in newborn for a long period of time. We distribute -- or sell our products in 93 countries. And so when we look at the opportunities, I would say right now in the short term, we talked about India, I think that will be -- it's a significant opportunity, but it will probably ramp over a number of years. The other ones that we're in fairly active discussions with is Indonesia and Vietnam. And then I think when you get sort of to the '18 time frame, we actually think there's some interesting opportunities in Russia. And I think in all of those, I don't think the barrier is going to be our commercial capabilities. So I think as we look at the runway for newborn screening in emerging markets, we feel good about our ability to sort of support that from an infrastructure standpoint. Having said that, I don't want to sort of ignore the developed markets because I think there are some nice opportunities there as well. We think probably as we get towards the end of this year or early '18, we'll come out with an LSD assay panel. And eventually, we'll get that CE IVD as well. So I think there's a -- when you look across newborn screening, there's a nice path over the foreseeable future to sort of continue to grow that in the sort of high single digits. Second question was around the academic market, I believe, and what we've seen from a geographic perspective. And we saw actually strength in Europe. The U.S. was down sort of mid to high single digits and actually APAC was down a little bit. So that was the geographic split of our academic business. Again, it was largely in Europe. I think there were some episodic sales there that probably drove that to some extent. And maybe, Andy, wants to comment on some of the specifics.
Frank A. Wilson - CFO and SVP
Sure. Well, I was just going to talk about the industrial piece because you had indicated that it was a part of our guidance. We, going into the year, did not expect significant improvement. And I think we're encouraged up to this point given the flat performance in the first quarter. It looks like the order trends are supporting that and I think the new products that we're going to launch in DAS are going to also be helpful. So I think maybe at this stage, we're a bit more confident in the industrial piece of our guidance. And -- but we remain cautious because it's still fairly early in the year.
Robert F. Friel - Chairman, CEO and President
Yes. And I think what you may be recalling is when we talked about 2017, I think that we were concerned about -- because industrial has been challenging for us, particularly in the back half of the year. We just -- I think what you're -- we didn't want to get any worse, right? So I think we saw a continued deterioration in industrial. That would have been challenging for us, we believe, to continue to get our organic growth rate up to 4%. But to Andy's point, I think we're encouraged by what we see, at least through the first quarter of this year.

And our next question comes from the line of Bill Quirk from Piper Jaffray.
William Robert Quirk - MD and Senior Research Analyst
A couple of questions. First is, I guess, going back to India and the potential there for newborn screening. Is there any way -- and I realize that we've got slightly different call points and different organizations. But to what extent can you guys leverage Tulip and their relationships to try to accelerate your penetration there?
Robert F. Friel - Chairman, CEO and President
I think we can. When we announced the acquisition of Tulip, we talked about the fact that while we're excited about the product suite and the current channel that they have, we do think there's an opportunity to leverage Tulip because some of their products, they are actually going into the hospital labs. And so we think there's an opportunity. The other thing that I alluded to was we're seeing actually some demand coming from the private labs to do newborn screening. So we do think there's an opportunity to sort of leverage that a little bit more. And actually, they are calling on some of the pharma customers as well. And so we think there's a potential to leverage it actually in the DAS side.
William Robert Quirk - MD and Senior Research Analyst
Interesting. And then secondly, just on the restructuring. You've mentioned that you're continuing to look at some selected divestitures. In baseball parlance, Rob, can you give us a sense as to what inning we're in here in the overall strategic realignment?
Robert F. Friel - Chairman, CEO and President
I would say probably still fairly early from the standpoint of significant divestitures. And I think what we said -- for '17, I do not anticipate seeing anything of the size of medical imaging. I think what we're looking at right now is sort of maybe some relatively small product lines. So I think to see more significant divestitures would require us to be more successful on the acquisition side.

And our next question comes from the line of Paul Knight from Janney.
William March - Associate
This is actually Bill on for Paul. Maybe if you could just talk a little bit about your oncology segment and the NGS workflow. Illumina announced that they were getting out off of that segment. So maybe just opportunities to capture market and just your positioning within that market.
Robert F. Friel - Chairman, CEO and President
So as we've talked about in the past, our, really, strategy around here is sort of encircle the box, if you will, or encircle the sequencer. And we think we've built a nice capability in and around sort of sample preparation, automation, library preparation and those types of steps that are required. And particularly with the addition of bioscientific, I think it brought us some really strong capabilities there. So I think what we're really trying to focus now is to take those capabilities that we have and target those -- if they're very specific applications and looking to extend our workflow capabilities so that we can basically from sample to sequencer have a very efficient workflow. And so potentially, there's an opportunity with Illumina sort of realigning their priorities to continue to take share there.
William March - Associate
Got it. And then maybe just more holistically on the Diagnostics segment. That business is running at around a 30% operating margin. Can you maybe just talk about the maturity of that portfolio and how you guys think about maintaining a really high margin as opposed to investing in some of these newer products and categories that are a focus for you guys?
Robert F. Friel - Chairman, CEO and President
I think it's a constant balance between making sure that we are investing at the appropriate level but then also driving the growth and the efficiencies in our operating processes to make sure that we're continuing to get better. I think one of the benefits of the Diagnostic business is it has a very high percentage of reagents, so some 90%-plus of the revenue now is coming from reagents. So you get significant incremental flow-through when you grow. So as long as we can continue to grow at high single digits and get good flow-through from the profitability, I think it still allows us to do a fair amount of investing into R&D or building our capabilities from a distribution perspective.
Frank A. Wilson - CFO and SVP
Yes. I don't see Diagnostics anywhere near operating margin maturity. And as Rob mentioned, I think there's fairly significant incrementals on the higher volume. We are cognizant of the fact that we've got to continue to invest. That's why in my prepared remarks, we talked about operating margins growing at a slightly lower pace than DAS because of those investments. But I think we think long term, there's still operating margin expansion opportunities in that segment.

And our next question comes from the line of Jack Meehan from Barclays.
Jack Meehan - VP and Senior Research Analyst
Rob, I was wondering, could you provide some additional color on trends in the U.S. market and then what you're seeing here in terms of birthrate?
Robert F. Friel - Chairman, CEO and President
So when you say U.S. market, are you talking about sort of globally all our products or just specific to newborn?
Jack Meehan - VP and Senior Research Analyst
Both. I think you mentioned in the prepared remarks a low single-digit decline in the Americas. Is that right?
Robert F. Friel - Chairman, CEO and President
Yes.
Jack Meehan - VP and Senior Research Analyst
And then within that -- so maybe just U.S. in aggregate and then birthrate specifically.
Robert F. Friel - Chairman, CEO and President
Yes. So if you look at birthrates, our data would suggest that birthrates in the U.S. are up about 1.5% when you look at first quarter '16 versus first quarter '17, so a slight increase in birthrates. If you looked at our newborn, our reproductive health business, it was down slightly year-over-year. I think the biggest driver to that was a very difficult comp. It was very strong growth in the first quarter of 2016. So we still think, if you look at the full year, we'll grow in the U.S. probably mid to high single digits.
Jack Meehan - VP and Senior Research Analyst
Great. And then I was just wondering if you could give us an update in terms of blood screening and where you thought we were in terms of the penetration within China and the growth for that business, too.
Robert F. Friel - Chairman, CEO and President
So we saw very strong growth in that business in 2016, if you recall, as we placed the instruments out into the various testing labs. Our expectation is for 2017, that's going to moderate as it goes against some very difficult comps. So what we're seeing in Haoyuan or the blood screening business in China is lower growth. And actually, for the first quarter, it was actually down a little bit but higher margins because what we're selling now is basically reagents. And so I would say, at this point, you're not going to see the significant instrument placements that we saw in 2015, 2016. And you'll see a more normalized growth, which we still think would be significant because as the Chinese ramp up more blood screening. But we are, for 2017, cycle begins with very strong growth as we were placing those instruments out into the lab. Having said that, our Diagnostic business grew north of 20% in China.

And our next question comes from the line of Derik De Bruin from Bank of America.
Derik De Bruin - MD of Equity Research
So a couple of questions. So first off, can you -- you mentioned something about Vanadis assay. Could you give us some thoughts on how you're thinking about pricing that assay? The first question.
Robert F. Friel - Chairman, CEO and President
Well, you know what, we haven't, Derik, gotten into the pricing yet. I think we're going to wait until we get closer to launching into the marketplace. So we're not really discussing pricing right now. I think one of the things we've talked about, though, is the goal is to try and be competitive both from a workflow perspective and a price with biochemical screening.
Derik De Bruin - MD of Equity Research
Yes, fair enough. Remind me what the margins are on the OneSource business.
Robert F. Friel - Chairman, CEO and President
Well, OneSource now, we are sort of rebranding as our entire service business now. So when we talk about OneSource, I talked about it in my remarks, it's $600 million large service business. So our service margins are a little bit higher than the corporate average.
Derik De Bruin - MD of Equity Research
Got it. Okay, that's what I thought. Did you -- correct me if I'm wrong -- if I missed it. But did you say anything about what you were thinking about the 3% or 4% organic revenue growth guidance? What's -- that's embedded for the segment organic revenue growth? Are we looking at about -- just what's your embedded expectation again?
Robert F. Friel - Chairman, CEO and President
I don't know that Andy talked to it. But I think you're going to see closer rates between DAS and Diagnostics. And one of the reasons is -- so it will be -- they will be closer, alike than -- for example, this quarter was sort of 8 and 2. And the reason for that is, I think, the Diagnostics grew, Andy, what, 12% last year or something? So they've got a tough comp in Q2. So I think you'll see very similar growth rate is at least what we're forecasting between DX and DAS in Q2.

And our next question comes from the line of Catherine Schulte from Robert W. Baird.
Emily G. Stent - Research Analyst
This is actually Emily on for Catherine. Just want to touch on, first -- so after divesting medical imaging, can you break out your new exposure by end market by pharma, academic, diagnostics, industrial, applied? I know previously you had said a decent amount of your academic exposure was in medical imaging. We're just trying to true up what the new model looks like.
Robert F. Friel - Chairman, CEO and President
Yes. So I'll start and Andy can -- so we think of Diagnostics and pharma, biotech as sort of equal at around 30%. Then you've got sort of academic and government at sort of 10% and industrial in that range as well. I mean, maybe the way to think about it is industrial, academic, food and environmental safety are all roughly around 10%, basically.
Emily G. Stent - Research Analyst
Okay, perfect. Yes, it does. And then I don't recall if you said this earlier on the call. But could you walk us through what's embedded in your guidance assumptions for growth rates by end market for the year?
Robert F. Friel - Chairman, CEO and President
For the year, for 2017?
Emily G. Stent - Research Analyst
Yes.
Robert F. Friel - Chairman, CEO and President
Hold on a second. So I think we're looking at pharma and biotech sort of mid-single; we have academic and industrial sort of flattish; environmental similarly is sort of mid-single; and then food, high single. That would make up the sort of DAS split. And then within Diagnostics, I think we talked about -- I think it was 7% for the year.

And our next question comes from the line of Bryan Brokmeier from Cantor Fitzgerald.
Bryan Paul Brokmeier - Senior Equity Research Analyst
In your prepared remarks, you talked about the automated GSP adoption in China is enabling the menu expansion. Where are you today for the number of tests on average that are being tested? And how is that in China? And how does that vary across sort of the larger hospital, those sort of coastal cities versus other parts of the country?
Robert F. Friel - Chairman, CEO and President
So I mentioned a little bit before, 90% penetration in China right now. Think of that as about 70% of those are screened for 2 to 4 disorders and about 20% to 25% is doing the mass spec and the GSP, either/or, and that's going to take up closer to like low-20s. So we've got 1/5 of the babies being screened in the sort of low-20s and the remainder in low single digits. And the split is largely going to be sort of East Coast, West Coast. So larger on the East Coast is where you're going to see the higher screening. And as you got out more to the western part of China, you're going to see the lower number of test.
Bryan Paul Brokmeier - Senior Equity Research Analyst
Okay. And could you update us on where you are in India? I think, previously, you had indicated that you had 1 or 2 regions that had adopted and a bunch of other that were in pilot programs?
Robert F. Friel - Chairman, CEO and President
Yes. So India is still relatively slow ramp-up. I would say less than 5% of newborns are being screened in India. And I would say the uptake is -- as far as sort of official programs, it's still at the sort of 2 to 3 stage. There's a number of ones that are in pilot programs. But a lot of these pilots rather than being done state-wide have a tendency to be in institutions. So they may be in universities, they may be in medical institutions, et cetera. So a lot of the pilots, we'll just have to see how they ramp up. But I think we said on a number of occasions, while India is a significant opportunity with 27 million births, I think it's going to be a fairly slow ramp.
Operator
And I'm showing no further questions at this time. I would like to turn the call back over to Rob Friel, Chairman, Chief Executive Officer for closing remarks.
Robert F. Friel - Chairman, CEO and President
Great. Well, first of all, thank you for your questions. And as I've said before, I think we're off to a solid start to the year and encouraged by the progress we are making to drive innovation while achieving profitable growth in advancing our mission. So we appreciate your interest in PerkinElmer, and wish you a great evening.
