Thank you, Nicole. Good afternoon, and thank you for joining us on our call today to discuss our second quarter 2019 results. I will review the highlights from the second quarter before Paul discusses our financial results and our growth in detail. We had a second quarter easily achieving quarterly results for both test volume and the revenue. At the same time, we found equal and equal margin and achieved a record cost per sale which should lead to very good and GAAP profitability in the quarter. Essentially revenue grew 56% year-over-year to $8.4 million. Billable test increased 187% year-over-year for new record high of 16,369 far exceeding the [indiscernible] of last quarter for at least 10,000 tests. With the strong warning, we have now reported more tests in the first half of 2019 than we created in all of 2018. Our GAAP was $515. Our ASP was $515 down from the 8% compared to the first quarter of 2019. However, it was offset by the record low cost of protest of $251 which was an improvement of 44% compared to the first quarter. The lower ASP continued to count on product mix volume and efficiency which will be discussed further in a moment. Non-GAAP gross margin in the second quarter was 69% up approximately 330 basis points from the second quarter last year and up approximately 4% sequentially. GAAP income was $331,000 and non-GAAP income was $1.2 million. Non-GAAP earnings per share was $0.06 in the second quarter. Adjusted EBITDA was positive $1.5 million in the second quarter. The strong growth was demonstrated in the second quarter, were achieved of ongoing traction we're having in the breadth of our offerings across our volume customer base. And with our collaboration agreement, the majority of growth in a test volume that we saw this quarter was driven by demand from our core clinical business increasing level of momentum with our core test. Well, our reproductive health and service for sequencing and research data analyzed continues to work. The large warning tests were able to essentially in the quarter, demonstrate how our investments in technology capabilities and infrastructure kind of set us up for future success. In addition to the strong one for the opportunity in this quarter, we are pleased with the leverage we saw in our business, which resulted in that capacity. We saw a meaningful improved margin result from our input costs per test which benefited from scale, automation and efficiency with writing wall. Our comp protest is good from start with the conversation was a record low of $200,011. We believe this enable us to serve more opportunities, as well as we think with advantage to compare in any environment. We also saw great leverage with operating expense, generally warning and revenue with a minimum incremental sales and overhead costs. As we have discussed in the past, we have invested meaningfully in our technology, infrastructure and talent in the last few years to create a scalable business capable of handling higher warning. Now that we are capturing foreseen quarter inquiry we're pleased with our ability to reduce this demand in an efficient manner without having to opportunity, operationally to learn more to achieve these results. The market for the next-generation sequencing and a generic text is a large and growing. We are uniquely positioned to capture this market share with our differentiated technology and approach. The collaboration agreements that we have continued to announce demonstrated that organizations and institutions when you are our outing because of our unique technology and ability of a wide range of customized tests that meets individual needs. And with the flexibility of our offering, partners are able to better leverage our sequencing capabilities to deliver more informed and extra care for their patients -- attending patients. Another example of a partnership agreement that we have announced. This was with the Parkinson Foundation. The foundation was looking for a genetic testing partner to help them with a nationwide initiative that we will launch to provide the eligible individuals with a genetic test for clinically relevant to Parkinson related G. After a competitive process, the foundation select a partner with Trojans, because we offer the best customer solution and the overall value for the organization. We'll become into product processing, sequencing, analyzing and then storing each DNA samples for the patients in the initiative. In addition to supporting the individual test, we were able to use the data that we got in to assist Parkinson Foundation, new research and development of new treatments for the disease. We are finding ongoing dialogue with a number of other large organizations and institutions for potential future collaboration. And we are pleased with the diverse scope and geographical reach that we are seeing with this opportunity. To increase the number of opportunities that we are seeing is a testament of our work to pure technology capabilities and our ability to offer partners flexible and accountability effective solution. We believe this type of partnership will continue to drive momentum of our business. We also have exclusive several collaboration agreements with our sequencing as a third business with the words of biopharma and the research institution and that we expect to see revenue from this collaboration in the second half of this year. Moreover, they have made additional programs of our reproductive health care and intuitive introducing new offerings to the market in the later part of this year. We have one more recent highlights to discuss. Last week, we were very excited to announce that we have received the approval from New York State Department of Health for NGS healthy in the state of New York. This approval is an authorized zip coding to cheap and that we are pleased that we have a process and approach due to a rigorous standards set by the states. A testament to our technology. They've expand our presence in and out either U.S. and open up additional opportunities for collaborations with our partners and institutions in New York. Finally, we're pleased to welcome Linda Marsh to our board of directors, which we announced in a press release this month. We are excited to have Linda joining us. Her knowledge and expertise in the healthcare industry, government relations, analyst in person will bring great insights to our board. We look forward to working with Linda in the years ahead. In summary, we had a very strong start to the year and as we look ahead, the rest of 2019 we feel comfortable in our market position and opportunity. We have a very solid pipeline to fill up. And we expect to continue these strong test of wanting growth and profitability in the quarter ahead. I would like to now turn over the call to Paul to provide details on our financial performance in the second quarter. He will also provide an update on our financial outlook for the full year 2019.
