Thanks, Lynn. Good afternoon, everyone. As we have done our previous quarterly calls, I’d like to start this update with a patient story. Many of you may have seen recent news on the double-hand transplantation, eight year-old, Zion Harvey. Zion was an ideal candidate for a hand transplant due to his previous kidney transplant. I encourage you to look up Zion’s story and watch the videos about his experience online. Zion’s care is provided by the transplant program at Children’s Hospital of Philadelphia. It is for patients like Zion, that we at CareDx come to work every day. This call marks one-year since we completed our IPO, we are proud of the progress that we are making towards our milestones. In particular, we are advancing the utility of cell free-DNA as a biomarker in organ transplantation, and moving cell free-DNA more and more to the center of our attention. Accordingly, I would like to start this call by covering the recent highlights in our cell free-DNA pipeline and clinical development. I’ll next cover the updates in our AlloMap business, where our focus continues to be increasing patient access to AlloMap as a surveillance tool in heart transplantation. Ken will cover the financials for the second quarter and our guidance for 2015. And then, we look forward to your questions. Before we go into those specific updates, I’d like to reiterate our three strategic objectives for the year. Number one, develop cell free-DNA tests in transplantation; number two, increase the utilization of AlloMap; and three, add momentum through realizing inorganic growth opportunities. Before moving to the pipeline, let me touch on our second quarter financials. Total revenue was $7.1 million in the second quarter of 2015. AlloMap test volume reached a record-level in the quarter and continues to be a strong foundation for our business. In the quarter, we increased R&D and clinical expenses according to the previously outlined objective to develop new transplant surveillance solutions. These additional expenses were mainly driven by planned increases to our headcount, which now include 84 full-time employees versus 55 at the IPO, and secondarily by anticipated clinical trial costs, as we ramp-up our cell free-DNA program. I’m pleased to the progress we have made towards the milestones we set for the development of our cell free-DNA program. Earlier this year, we executed against our objective that we had outlined during the IPO road-show. We were able to leverage our existing sample database in heart to establish the proof-of-concept of cell free-DNA in transplantation and demonstrate the correlation with organ rejection. This data highlighted at symposia during ISHLT and ATC, reconfirmed cell free-DNA as a biomarker for rejection. We are now moving ahead with the development of an analytically-validated assay available through our CLIA lab. We have set year-end 2015, as our target for delivery and the team is executing well against that milestone. We have also made good progress our DART trial. As a reminder, this is an observational study designed to demonstrate the clinical performance characteristic of cell free-DNA in detecting clinical and sub-clinical rejection in kidney allograft recipients. The study is also designed to demonstrate the correlation of circulating cell free-DNA to renal function using both serum creatinine levels and estimated GFR. In the first phase of the DART study we expect to enroll 200 patients in 6 to 10 centers, and collect patient blood samples over a period of 18 months. As planned, we are proud to share that we have conducted side initiation visits at six transplant centers as of June 30, 2015. The participating centers and key opinion leaders are some of the leading doctors and transplant institutions in the country. They include Dr. Poejo [ph] at Cleveland Clinic, Dr. Bromberg at University of Maryland, Dr. Hariharan at University of Pittsburgh Medical Center, Dr. Bloom at University of Pennsylvania, Dr. Matas at University of Minnesota, and Dr. Fischbach at Dallas Nephrology. As is our practice with all clinical activities, we plan to provide updates on center and patient numbers on future calls. We are on track to deliver an interim readout in the first-half of next year with the timing primarily driven by the number of patient samples that are associated with clinical events, especially rejection. Following the interim analysis of DART 1 study, we plan to begin the second phase DART 2, a clinical utility trial in the second-half of 2016. These milestones are consistent with previous communications and we continue to be on track. With the size of the kidney transplant surveillance market estimated at $1 billion. We are obviously very excited about the potential for a cell free-DNA kidney transplant surveillance testing solution. As we are developing cell free-DNA solutions, we are also building capabilities that allow us to significantly impact the management of patients. It takes a village, not only at the transplant centers, but also for us as a company to provide novel surveillance solutions. In this context, you will hear us and especially our CSO, John Sninsky, talking about shaping an ecosystem. As a first example, let me talk about our patient test results portal. We began communicating clinical information via secure and HIPAA compliant internet connections through the CareDx web portal for client institution. Being in some of the top hundred leading medical institutions in the U.S. and building communication links that allow for instant interaction is valuable for future patient management activities. The success of this tool has encouraged us to further expand our Internet portal in the future. The Department of Health and Human Service decision last year to amend the CLIA regulation enables laboratories to provide direct patient access to completed laboratory test reports. As a small dedicated company, we see this as an opportunity to innovate and be part of improvements in the overall healthcare delivery system. As a second example to the ecosystem, we recently announced a new relationship with DNAnexus, a leader in cloud-based genome informatics and data management. This collaboration will enable us to stay at the forefront of the evolving molecular data revolution in clinical diagnostics. The volume of data derived from next-generation sequencing technology is immense. In addition, the demands of analyzing, storing, retrieving and presenting that data, necessitates high-quality scalable computing platforms. We believe that the collaboration with DNAnexus will put CareDx in a unique position, because it will allow our bioinformatics team to develop solutions that deliver patient results in an effective and cost efficient manner. The third example to the ecosystem, we also began a collaboration with Horizon Discovery Group, which is important since it help us to define reference standards in the evolving field of cell-free DNA. We have learnt from the noninvasive prenatal testing companies that there are difficulties when describing performance characteristics of diagnostic tests. This is also true in the field of transplantation. There are tests in transportation that make uniform interpretation difficult, because they greatly differ from one lab to the other. With Horizon, we will have an approach available through a reference standard that allows comparability. Our Internet portal and recently announced relationships with DNAnexus and Horizon highlight our approach to develop a best-in-class transplant diagnostics information ecosystem. And there’s more to come. Our investment in digital capabilities and high quality information will remain a cornerstone of our corporate innovation strategy. Apart from DART, we have two more clinical studies underway, our Outcomes AlloMap Registry study or OAR, and our cell-free DNA Outcomes AlloMap Registry or D-OAR. Starting with OAR, we continue to see growing enrollment. More than 1,700 samples from 548 patients enrolled in the study were received from 20 centers as of June 30. This is up from 1,300 samples at the end of first quarter of 2015. The long-term outcome data collected will continue to build clinical evidence for the use of AlloMap. We see this not only as a long-term commitment to the field, but also an invaluable source for future scientific insight generation. We continue to make cell-free DNA available for heart clinicians as a research-use only test in combination with AlloMap through our D-OAR registry. D-OAR has been launched in 13 centers for the 135 patients enrolled and 252 samples collected as of June 30. Both the number of samples collected and the patients enrolled nearly doubled in the quarter. This effort continues to support the evidence generation of cell-free DNA in transplantation. Now, turning to AlloMap, our surveillance solution for heart transplant recipients, we continue to see good volume growth in the second quarter. AlloMap was used for heart transplantations more than 3,250 times a record-level, representing an increase of 8% over the second quarter of 2014. Our focus is on increasing AlloMap adoption, which provides the foundation for growth for our business. Out of the 130 heart transplant centers in the U.S., AlloMap was used in 115 during the last 12 months. As of the end of the second quarter, there were 60 centers with established AlloMap protocols up from 58 in the previous quarter. I am upbeat by the early progress we are making with our new commercial strategy which coordinates AlloMap patient customer engagement, drive the establishment and adherence to protocols and supports transplant centers in optimizing their workflow. Following the appointment of Josh DeFonzo in the commercial leadership role, we have divided the territories in the - into East and West, and have hired two experienced managers to direct the surround sound system selling process in transplant centers. We are making this progress through several new initiatives. The first is stakeholder engagement. This encompasses patient and healthcare professional engagement. Tactics include patient advisory boards and a newly formed visiting clinician program. Also we focus on protocol development, the main focus here is to continue to expand the utility of AlloMap and how it is used in post-transplant surveillance. The next growth driver relates to improving workflow. Earlier, we mentioned the web portal which is a great way to digitize user experience and improve the ease with which clinicians order, patients undergo, and patient results are received. Another important initiative centers around clinical data and education. With continued efforts like OAR, D-OAR and Investigator-Initiated Research, we will continue to increase supporting clinical data on AlloMap. Last, but not least, we have targeted product development. Now, this is exciting. Our team is preparing for the release of AlloMap variability as an additional tool for heart transplant clinician. This is a particularly exciting area for patients that are in the years two to five years post-transplant. AlloMap variability which is available from four AlloMap test results within a 24-month period will help clinicians with patient risk stratification. Early data suggests that patients with higher score variability tend to have poorer outcome. We believe that this will further enhance our heart transplant surveillance offering. As you know, we believe the total addressable market for AlloMap in the U.S. is approximately $100 million. Patients in the two to five year segment represent about $40 million U.S. of the market, a segment that we are serving at approximately 30% thus far. We will be introducing this concept to interested centers at the Heart Failure Society of America meeting in National Harbor, Maryland this September. As we have always said, we believe a center-by-center approach is necessary to make material changes in the way transplant centers monitor and support their patients. With the organization that we are building in the field, and application of the right initiative at each center, I’m confident that we have the commercial infrastructure to drive future growth in heart transplantation. The third quarter represented a good start. On the reimbursement front, we continue to have positive coverage decisions from all the major carriers. As of June 30, 2015, we had been reimbursed for approximately 80% of all AlloMap results delivered in the 12-month ended December 31, 2014. AlloMap continues to be broadly reimbursed in comparison to other high value molecular diagnostic offerings. We expect reimbursement to remain in this range going forward. As you may recall, we announced earlier this year that the American Medical Association included AlloMap in its recommendation for a test-specific Category I CPT code, demonstrating that an additional independent organization has reviewed AlloMap and has deemed an unique CPT code is warranted. The effective date for the CPT 1 code should be either January 2016 or January 2017 depending on how CMS interprets the anticipated PAMA regulations that are not yet finalized. We share the expectation of industry experts, that a change in Medicare reimbursement from current levels in either crosswalk or gap tool scenarios is unlikely. We recently resumed marketing responsibility for AlloMap in Canada from LifeLabs, and were approved by the Ontario Ministry of Health for reimbursement coverage of AlloMap at $3,600 million, under the out-of-country reimbursement program. While, this is a positive outcome, as more patients now have access to AlloMap, we continue to expect only modest contribution of ex-U.S. sales in 2015. Let me summarize my part today with our upcoming milestones. Our first milestone rollout of AlloMap variability September 2015, second milestone being the cell-free DNA availability through CareDx CLIA lab at December 2015, and the interim analysis of the DART 1 study in the first-half of 2016. I will now turn the call over to Ken to review our financial highlights and to provide guidance for the year.
