Peter Maag -- Chairman and Chief Executive Officer

Thanks Greg and good afternoon everyone. I am pleased to welcome you to the CareDx call reviewing our results for the fourth quarter and full year 2019. Before we dive into the results I wanted to highlight Robert Montgomery many of you may have seen the news flow on Rob a kidney transplant surgeon who recently received a heart transplant himself. Rob is not only using AlloMap and AlloSure for his heart transplant surveillance but he will also be speaking at the upcoming CEoT conference and introduce our immune optimization study called CIRA. It is for patients and clinicians like Rob that we at CareDx are coming to work every day. Together with the transplant community we have built a tremendous platform in transplantation over the last 20 years. Now turning to results. 2019 was a very exciting year for CareDx as continued momentum for our high-value healthcare solution for transplant patients and caregivers drove robust revenue growth. Our full year revenue was $127.1 million representing 66% growth over the prior year and clearly exceeded our most recent guidance range of $124 million to $125 million. For the fourth quarter of 2019 total revenue was $35.8 million increasing 52% compared to the year ago quarter.

The majority of the growth in the quarter came from our testing services revenue which increased 55%. Product revenue for the quarter was $5.1 million and digital revenue added $1.6 million to the top line. With us again posting positive adjusted EBITDA in the fourth quarter we feel very comfortable about the execution of our plan to build a powerful platform in transplantation. CareDx has never been stronger. Digging deeper into our testing services for the fourth quarter CareDx provided 14055 AlloSure kidney and AlloMap heart results to transplant patients in the quarter growing 63% from the 8632 results in Q4 2018. Since launched in October 2018 over 150 centers have provided AlloSure results to their kidney transplant patients. By end of 2019 over 30 transplant centers in the United States had adopted an Allosure testing protocol into their standard of care. We are pleased to announce that enrollment in our kidney allograft outcome AlloSure Registry or K-OAR study is nearly completed. We have a total of 55 centers in the study. The study called for 1500 patients to be monitored using our AlloSure protocol of 15 tests over three years.

So for the next three years the study centers will continue to observe transplant patients for kidney allograft issues and patient data will continue to be mined for vital insights driving this field over. Just recently we announced that the American Journal of Transplantation accepted for publication a paper titled high levels of donor derived cell-free DNA identifies patients with T cell-mediated rejection 1A and borderline allograft rejection at elevated risk of graft injury. Based on the data presented in this paper which shows AlloSure's ability to discriminate the clinical relevance of T cell-mediated reduction or borderline biopsies we believe AlloSure will ultimately change how clinicians care for transplant patients who have ambiguous rejection based on biopsy read. This study may help define the term liquid biopsy for transplant medicine. Turning to our OKRA study. OKRA stands for Outcomes of Kidney Care in Renal Allograft. We began enrolling patients in September 2019 and enrollment continues to ramp nicely. As a reminder this multicenter prospective observational clinical trial is designed to measure outcomes of kidney transplant recipients managed with kidney care the combination of donor-derived cell-free DNA using AlloSure gene expression profiling using AlloMap and prognostic graft assessment using iBox.

The OKRA study is designed to ultimately include 4000 patients adding in our previous multicenter prospective study. This gives us an extensive and in-depth set of patient outcome. Over the next five years we expect significant data and findings from K-OAR and OKRA. These findings will not only be published in peer-reviewed journals but will ultimately lead to changes in the way patients are medically cared for after transplantation. For example based on the analysis and data of the first 7000 K-OAR samples and the recently published TCMR data we were able to identify clinical relevance of AlloSure between the 0.2% and 1% level which is very exciting since these new insights can directly impact clinical decision making. Now shifting to heart. AlloMap testing volume grew solidly in the fourth quarter. HeartCare the combination of AlloMap and AlloSure Heart gained great traction in the cardiac transplant community. This traction might be driven by our ongoing Surveillance HeartCare Outcomes Registry or SHORE. As of December 31 2019 we had recruited 39 centers into the SHORE study. In the fourth quarter product revenue increased 10% compared to the year ago quarter.

We expect our two recently launched product AlloSeq Cell-free DNA and AlloSeq Tx which created a lot of enthusiasm at our global beta sites to start to generate revenue in 2020 and to help drive growth and global expansion this year and beyond. Revenue from our digital solutions was $1.6 million for the quarter. This revenue was generated from our software solutions which are used in 84 transplant centers in the U.S. many of which have also adopted AlloSure AlloMap or both. Over the next year we will continue to expand our digital offerings including further embedding our AlloSure protocol into transplant center EMR platform. I want to take a few minutes to briefly summarize 2019 and offer some thoughts about 2020 and beyond. I'm very proud of the numerous successes our team has had over the past 12 months as we continue to advance CareDx as a true transplant company and as an essential partner to transplant patients and caregivers. In 2019 our clinical and marketing teams were very busy attending and presenting data at eight industry conferences.

At the American Transplant Congress in June we showcased 12 abstracts and hosted an incredibly well attended lunch symposium which included presentations from seven prominent leaders in transplantation. During the launch symposium we formally announced KidneyCare the combination of our clinically validated AlloSure testing with AlloMap Kidney and iBox which will deliver personalized and prognostic solutions for transplant patients. According to many of the clinicians that attended our symposium they not only see value in identifying when there might be an issue with a transplant patients but also the possibility of optimizing immune suppression in a subset of patients. As many of you know the side effect of immunosuppressants are not trivial. For example they carry the severe risk of infection. We strongly believe that the ability to personalize the approach to immunosuppressants will lead to better outcomes and quality of life for transplantation. With this approach CareDx promises to bring precision medicine to the transplant clinic.

This past November we had a significant presence at the American Society of Nephrology Kidney Week where three abstracts were presented on the utility of AlloSure as a surveillance tool and as a marker of allograft injury. As with all of the conferences we attended participant turnout at our booth podium presentations and symposium was exceptional. 2019 was also a productive year for our regulatory and reimbursement team as we received regulatory approvals and reimbursement wins for both AlloSure and AlloMap. In February 2019 AlloSure became available under a compassionate use program for lung transplant patients. In May Anthem Blue Cross of California and 10 of its affiliated health plans designated AlloMap Heart as a contracted service. With this change approximately 80% of all insured lives in the U.S. are now covered for AlloMap. In August AlloSure received a positive draft Local Coverage Determination for Medicare coverage in heart transplantation demonstrating the value AlloSure can bring to transplant patient care.

We expect MolDx will make a final coverage decision about AlloSure-Heart in the second quarter followed by pricing in the second half of 2020. In October 2019 BlueCross BlueShield South Carolina became the first private payer to issue a positive coverage decision on AlloSure Kidney and we will continue to work hard to expand coverage to even more patients in 2020. Finally in November we further advanced transplant patient care with the launch of AlloSure 3.0 our next-generation and continued transplant patient-focused improvement. This latest version of AlloSure provides better care with only one tube of blood required better science with the lowest limit of detection now at 0.12% and better insights by stratifying patients with T cell-mediated rejection. On the business development front we furthered our commitment to the transplant community by acquiring OTTR a leading provider of organ transplant patient tracking software and XynManagement a supplier of solutions to simplify transplant quality tracking and waitlist management. We also entered into a partnership with Cibiltech for its iBox technology a data analysis tool that provides an early prediction of an individual risk of allograft rejection and transplant loss.

We believe these transactions will not only expand our direct patient reach but they will also deliver vital analytics to those providing care to transplant patients. Last but certainly not least in September our commercial team launched AlloSeq Cell-free DNA our kit-based donor-derived cell-free DNA surveillance test and AlloSeq Tx the first of its kind next-generation sequencing HLA-typing solutions utilizing hybrid capture technology. Now looking ahead 2020 should be even more exciting as our pipeline is full our clinical studies are enrolling quickly and providing robust data and we continue to enhance our digital offering. In 2020 we have several opportunities to continue our rapid growth. First and foremost is the continued adoption of AlloSure Kidney with only 4% penetration of this very large and growing market we are still at the early stages of adoption. With heart we anticipate seeing continued adoption of surveillance protocols for HeartCare and expect Medicare coverage of AlloSure Heart later in the year. With our products business we are excited about our newly launched AlloSeq Tx and AlloSeq Cell-free DNA product and our ability to accelerate our business overseas. 2020 will also see CareDx expand into stem cell and cellular therapies with our AlloHeim and AlloSeq HCT offering.

Finally we plan to expand our digital offerings by launching AlloCare our tool for kidney transplant patients which will be aimed at improving and enhancing patient engagement. Everything we do at CareDx has one focus and that is to be the leading partner for transplant patients and the transplant ecosystem with leading the Honor the Gift campaign CareDx is supporting the community in extending Medicare coverage for immunosuppressive medication. Overall we continue to receive positive news from HHS and the kidney health initiative. It is great to see transplantation being the news and even being singled out in the residential addresses and maybe more importantly healthcare budget. Community nephrologists large dialysis providers and the transplant community are coming together to increase the number of kidney transplants. It has never been a better time for CareDx to be a transplant-focused company.

With that I will turn the call over to Mike to discuss our financials and 2020 guidance.

Michael Bell -- Chief Financial Officer

Thank you Peter. Turning first to the income statement. Our fourth quarter 2019 testing services revenue increased 55% year-over-year to $29.1 million. The growth in the fourth quarter testing services revenue was primarily driven by AlloSure Kidney patient results. Although we did experience a lift in our AlloMap Heart testing partly due to transplant centers excitement over HeartCare and the use of surveillance protocols. Our fourth quarter product revenue increased 10% year-over-year to $5.1 million and our digital revenue was $1.6 million. Our gross margins continue to improve year-over-year. For the fourth quarter of 2019 the gross margin was 65% compared to a gross margin of 55% in the same period of 2018. On a sequential basis the gross margin was down slightly from the third quarter due to fluctuations in our estimated reimbursement rates by AlloSure and AlloMap which moved slightly up or down each quarter.

The non-GAAP gross margin for the quarter was 68% compared to 59% in the prior year quarter. It's worth highlighting that the non-GAAP gross margin for the testing services business for the three months ended December 31 2019 has improved to 76% compared to 66% in the same period of 2018. For the fourth quarter of 2019 net loss was $4.8 million compared to a net loss of $3.8 million in the same period of 2018. Our net loss per share was $0.11 for the quarter compared to a net loss per share of $0.09 in the fourth quarter of 2018. For the fourth quarter of 2019 our non-GAAP net income was $1.6 million compared to a non-GAAP net income of $0.3 million in the same period of 2018. Our non-GAAP net income per share in the fourth quarter of 2019 was $0.04 compared to a non-GAAP net income of $0.01 in the same period of 2018. As a reminder we define adjusted EBITDA as non-GAAP net income before interest income tax depreciation amortization and other expense.

For the fourth quarter of 2019 we recorded our sixth consecutive quarter of positive adjusted EBITDA with a gain of $1.5 million compared to an adjusted EBITDA gain of $0.8 million in the fourth quarter of 2018. Cash and cash equivalents at December 31 2019 was $38.2 million. We continue to hover around the breakeven mark for net cash used in operating activities using only $1.1 million of operating cash in the fourth quarter. Turning to guidance. We are providing our initial 2020 revenue expectations to reflect the continued growth of AlloSure as well as the other growth drivers outlined by Peter. And as such anticipate $165 million to $168 million revenue for the year. Our guidance does anticipate increased competition on Allosure but balances that with the expectation that additional market entrants will accelerate overall patient penetration. We feel very well positioned to continue to lead the field in bringing novel solutions to the transplant clinic. With that I will open the call for questions.

Questions and Answers:

Operator

[Operator Instructions] Our first question comes from Bill Quirk with Piper Sandler. Please proceed with your question.

Bill Quirk -- Piper Sandler -- Analyst

Great, thank you. And good afternoon, everyone. Good First question from me. I guess with respect to the 30 transplant centers who have incorporated AlloSure Kidney into protocol can you give us a rough estimate in terms of what they represent with respect to the total market?

Michael Bell -- Chief Financial Officer

Bill. Yes it's Mike here. I mean roughly we focused our targets on those centers in top 100 performing centers. I'd say that that 30 it's representing about 20% of the total.

Bill Quirk -- Piper Sandler -- Analyst

All right. Perfect. And then a couple of additional questions here. Mike I guess first I'll say thank you. And that is philosophically thank you for the revenue guidance but help us think a little bit about some of the puts and takes with respect to operating expenses? Should we expect this to be another big ramp up here given the clinical trials and obviously the entrants of competition? Just help us better understand how to think about the pacing over the course of the year.

Michael Bell -- Chief Financial Officer

Yes. Bill I'd say last year we had a big ramp up in sales and marketing expense particularly in the first half of last year. And we feel on the sales and marketing side now we're pretty much fully fleshed out with the sales force. We'll continue to add to that but we won't see the huge growth in sales and marketing expense in 2020. So maybe that's increasing something like a million dollars a quarter. You're right. On the research and development side that's probably the area of most investment for us in 2020 and we should see that research and development expense continue to grow throughout the year similar to how it grew in the last two quarters of 2019.

Bill Quirk -- Piper Sandler -- Analyst

Okay. Got it. And then last one from me and I'll let somebody else jump on. Can you talk a little maybe can you expand on your comments with respect to private payers. We certainly caught BlueCross BlueShield of South Carolina decision. How active are you talking to other private payers? And then also does the guidance or model assume any expansion of coverage?

Peter Maag -- Chairman and Chief Executive Officer

Well thank you very much Bill for the question. I think the team is focused on engaging property payers just as a reminder 70% to 80% of our patient population are Medicare patients and so private payers are really outside. No we don't see any we don't have modeled into our guidance any significant upside in this year. But the team is continuously working on that and are doing a great job and we have established relationships with AlloMap our heart transplant solution. So there should be some level of uplift on the AlloSure this year. But we're still thinking that this is very early in the process we thought only 5% penetration we have ample ways to go. And only a few centers we have now critical mass to engage with private payers to make sure that they're also covering in kidney transplant patients for their surveillance. So our current guidance is not including maybe a little bit of an upside through to private payers in both.

Bill Quirk -- Piper Sandler -- Analyst

Very good. Thanks, Peter.

Peter Maag -- Chairman and Chief Executive Officer

Thanks, Mike.

Bill Quirk -- Piper Sandler -- Analyst

Thank you.

Operator

Our next question comes from Brandon Couillard with Jefferies. please proceed with your question.

Brandon Couillard -- Jefferies -- Analyst

Thanks for that.Peter Mike maybe a bit of a follow-up on Bill's question there. Just talk to us about philosophically how you approach setting guidance for the year in the context of competition the degree to which the guide kind of handicaps for that dynamic? And any numbers you can help us with to sort of understand the approach?

Peter Maag -- Chairman and Chief Executive Officer

Well Brandon thank you very much. I think our guidance continues to be following our AlloSure adoption that's our key lead for growth in the company. And here we have seen some linear growth adoption in transplantation which we see also if you benchmark us to specialty pharma or other transplantation products that there is linear adoption that the solutions are adopted in various transplant centers. We have started extremely strong into 2020 and we will be updating guidance as we report on the first quarter again. So as we're thinking into 2020 yes we have the uncertainty around competition entering the field. But we just only recently learned that probably their commercial launches are delayed to our previous expectations which is not reflected in our guidance this year. Again so no there is a balance of competition coming but also maybe competition expanding our market and increasing the opportunity for accelerated growth in patient adoption of surveillance tools for cell-free DNA and especially AlloSure.

Brandon Couillard -- Jefferies -- Analyst

Okay. And I understand that you're kind of consolidating AlloMap and AlloSure volumes as far as you report now but just sort of think about the heart business in 2020. Would you expect AlloMap to kind of return to that more normalized to mid-single-digit type growth level? Or do you think AlloMap Heart and excuse me AlloSure Heart and some of the surveillance efforts you're making can maybe push that up a little bit of the year?

Peter Maag -- Chairman and Chief Executive Officer

I'll let Mike speak to it but our heart franchise is working extremely well based on the great combination of AlloMap our gene expression profiling tool together with our cell-free DNA testing AlloSure. The short trial is really adopting extremely rapidly. There are so many centers in the U.S. excited about joining the call. So the heart franchise has been a bit of a surprise in 2019 and we are starting 2020 with great momentum. Mike did you want to make a comment?

Michael Bell -- Chief Financial Officer

Yes. Thanks Peter. Yes Brandon I'd say more specifically we still expect the uptake of the surveillance protocols on AlloMap that's been driven by HeartCare. So probably our guidance is expecting low double-digit growth for AlloMap so higher than the past forward this low single digit. So yes low double-digit growth.

Brandon Couillard -- Jefferies -- Analyst

Perfect. Good. And then last for me. Do you expect any major data readouts for the K-OAR study this year perhaps at ATC and any impact on as far as volumes that might be contemplated from that?

Peter Maag -- Chairman and Chief Executive Officer

Brandon that gives me just to put in a blanket for the American Journal of Transplantation publication on ambiguous rejection which is really carrying the existing K-OAR initial data set of more than 7000 samples received on K-OAR together with our insight that AlloSure is helpful in the stratification of a big use rejection which is incredibly exciting for us because it helps us to not only data mine K-OAR patients but also put it into context of what we learned on the TCMR the low-grade rejection. And so yes there will continue to be a readout. There's a tremendous wealth of abstracts that will be presented at the American Transplant Congress. I think cell-free DNA and especially AlloSure has been at the forefront of innovation in kidney transplantation and CareDx being the leader you'll see a lot of outflow of great clinical data not coming not only out of Care but also out of all the other clinical studies that we currently have ongoing. So a very exciting year for us on K-OAR.

Brandon Couillard -- Jefferies -- Analyst

Again, thank you.

Operator

Our next question comes from Alex Nowak with Craig-Hallum. please proceed with your question.

Alex Nowak -- Craig-Hallum -- Analyst

Great, good afternoon, everyone. Peter you highlighted a number of studies under consideration at the Analyst Day in January. I'm just curious have you finalized any of these? Which ones in particular should we be watching? And what is incorporated in the guide for new clinical studies?

Peter Maag -- Chairman and Chief Executive Officer

Yes. Thank you very much. I think the two studies to watch and see us execute against this year are really OKRA which is the combination of AlloMap and AlloSure together with the iBox solution which we call KidneyCare. And this is a similar effort undergoing combining the K-OAR study now with the OKRA study where we will have 4000 patients we call it the ultimate kidney transplant registry recruiting in more than 50 centers in the United States. We are well advancing on the recruitment on OKRA and we'll be updating on OKRA in the first quarter call because this is really for us a pivotal clinical trial in the KidneyCare combination. The second one is CIRA. I had started the call today highlighting our effort in immunosuppressive optimization with kidney transplantation.

This is a trial which is very exciting. If you think about it AlloSure is very very well-established already as a rejection monitoring tool. But maybe CIRA is pushing us toward immune optimization of kidney transplant patients. And demonstrating this in a large-scale study with multicenter engagement will be extremely exciting for the field and demonstrate security access cutting edge and pushing the because this is the holy grail in kidney transplantation and clearly exit at the forefront. So to just summarize OKRA and CIRA will be at the center. But then you see SHORE as our heart transplant clinical trials and then which is our international trial for cell-free DNA adoption as tertiary important. Now I will also put in that we are doing clinical studies on cellular therapies or stem cells. Our AlloHiem product is extremely promising and we're very excited about that type of product. And that will be detailed through clinical trials as well.

Alex Nowak -- Craig-Hallum -- Analyst

Okay. Great. Understood. And just want to come back on competition and just follow-up on Brandon's question. Are you hearing anything from the physicians you work with specifically around either switching or wanting to join your competitors' registry trial? Just anything that you're hearing that made you want to include competition into the guide at this point. Is there any way to quantify what you're assuming from competition too?

Peter Maag -- Chairman and Chief Executive Officer

As I said I think actually competition has increased the awareness of novel biomarkers in the field of kidney transplantation. So in a way this is CareDx has been trailblazing the field. And now there are other entrants. So I think this is creating awareness and I actually think that this will be leading to a much bigger market adoption going forward. In terms of very specific comments in individual tenders yes we hear other competitors placing their registries but we haven't seen any substantial clinical adoption of seeing real patients without being provided in a clinical setting. So I would say that there is maybe noise out there but it's incredibly difficult to quantify at this stage. But we feel extremely well positioned with our service offering on our SHORE and actually being a complete service provider for these transplant center. So we feel very well for this.

Alex Nowak -- Craig-Hallum -- Analyst

No. Understood. And actually just a follow-up on that last piece there. You did ramp up the patient management team over the past 12 months. I'm just curious are you seeing any change in patient compliance and how is this benefiting AlloSure people staying on the AlloSure protocol?

Peter Maag -- Chairman and Chief Executive Officer

Very good question. No there are some centers where we have 99% compliance rate 98% compliance rate. I think this is a center which is absolutely leading. And then we see some compliance rates with 55% which is a huge opportunity if we're combining that with our patient care management tool. Now overlaying this with maybe our software tool but with our auto offering where it's very convenient to engage patients into a longitudinal clinical trial. I think that would be that's very beneficial to CareDx and a huge growth opportunity going forward. So the patient care managers where we have direct interactions that have by and large experience in managing transplantations over a long period of time are going to be pivotal tool of increasing compliance and adherence not only to the AlloSure regimen and protocol that maybe even for supporting a longitudinal patient management for transplantations going forward.

Alex Nowak -- Craig-Hallum -- Analyst

Okay. Got it. And just last quick question for me. We saw a lung study get published on clinicaltrials.gov. Just where are you at from developing an AlloSure lung testing going through the reimbursement process?

Peter Maag -- Chairman and Chief Executive Officer

No. Thank you very much. We'll see submission of lung data this year into the MolDx program. I think we've not been setting time lines in terms of when lung will be reimbursed. It is somewhat a guarded opportunity. But lung AlloSure is available today on a compassionate use program. And as these clinical trials readout will be submitting to MolDx. This is probably more in terms of our reimbursement at 2021 discussion and relevant for revenues in 2020.

Alex Nowak -- Craig-Hallum -- Analyst

Okay, understood Thank you appreciate it.

Operator

Next question comes from Yi Chen with H.C. Wainwright. please proceed with your question.

Yi Chen -- H.C. Wainwright -- Analyst

Thank you for taking my question. Just to clarify the most recent publication AlloSure's ability to differentiate rejection is based on the original AlloSure but not AlloSure 3.0. Is that correct?

Peter Maag -- Chairman and Chief Executive Officer

It is based on AlloSure available at that stage. So it is combined at AlloSure and AlloSure 3.0 depending on which patient was recruited at what stage. I don't think that our AlloSure 1.0 2.0 three 0 would have any substantial impact on the level of measurement on donor-derived cell-free DNA.

Yi Chen -- H.C. Wainwright -- Analyst

Okay. So we can assume that the new patients enrolled in the OKRA study will have the AlloSure 3.0 because it's available now?

Peter Maag -- Chairman and Chief Executive Officer

Yes. No I think going forward any patient that's currently tested on AlloSure would receive the updated AlloSure 3.0.

Yi Chen -- H.C. Wainwright -- Analyst

Okay. So we shouldn't expect any significant differences in terms of further improvement of the result by using AlloSure 3.0 right?

Peter Maag -- Chairman and Chief Executive Officer

Well the clinical results the level of donor-derived cell-free DNA level will probably not change. Now I think we are talking here about marginal improvement but more importantly actually improvements in terms of how we service patients and the patient experience and the center experience with the lowest level of detection and the ability to differentiate TCMR 1A based on the data that we have.

Yi Chen -- H.C. Wainwright -- Analyst

Got it. Regarding AlloSeq cfDNA kit that's sold outside the U.S. does that revenue get recorded on the testing line or the product revenue line?

Michael Bell -- Chief Financial Officer

It's Mike. Yes that's a kit and it will be outside the U.S. And so yes when we have revenue for that we'll start including that in our product line. So the product line will be both pre and post transplant and it will be for the kit business not the U.S. testing service business.

Yi Chen -- H.C. Wainwright -- Analyst

Got it. Do you expect any significant growth for sales outside the unit outside of U.S.?

Michael Bell -- Chief Financial Officer

Well a lot of our strategy on the product side and the launch of these products is to enable us to expand outside the U.S. I think when we look at our product business last year or in 2019 the growth was overall 10%. And in our guidance we're looking at the growth now for the product business of around 20%. So that's coming from the new product launches. And again most of the AlloSeq Cell-free DNA outside the U.S. so some of that growth coming from out of the U.S.

Yi Chen -- H.C. Wainwright -- Analyst

Thank you.

Operator

We have reached the end of the question-and-answer session. At this time I'd like to turn the call back over to Peter Maag for closing comments.
