Good morning, everyone, and thank you for joining us. We're starting 2026 off well. Today, we reported record first quarter revenue of $17.3 million, up 12% year-over-year and with continued improvement in profitability metrics as we execute our plan. Gross margin was 59% and adjusted EBITDA loss reduced to $2.2 million, a 14% improvement versus last year. These results continue our efforts to build Exagen into a durable company that compounds value over time by prioritizing 3 core objectives: expanding adoption of our products, increasing ASP through disciplined revenue cycle execution and delivering a steady cadence of innovation that meets the unmet needs of our clinicians. Q1 was another good example. We are executing and our strategy is working. At the same time, our mission remains our anchor point. Autoimmune disease is still a category where patients often struggle to get clear answers and clinicians lack the tools to diagnose and treat with confidence in a timely manner. We exist to change that, and we'll do so by pairing better science with best-in-class execution. Our innovation efforts are on track, and we believe Exagen is well positioned to bring clarity to the complexities of autoimmune disease, ultimately improving outcomes for patients. When I look at our market opportunity, I'm incredibly energized by what's ahead. Drawing on our knowledge of the space and third-party research, we estimate the autoimmune testing market at over $2.2 billion, growing about 5% annually. With just over 3% market share today, we believe there is significant and realistic opportunity to systematically gain share by bringing better science, more timely results and world-class service to our underserved channel. Driving adoption within that opportunity will be central to volume growth. And in the first quarter, AVISE CTD test volume grew 10% year-over-year, which compared to a 5% market growth rate suggests we continue to earn share in the quarter. Test volume remained in the mid-30,000 quarterly run rate range. I feel very positive about that performance, especially in light of a couple of week disruption related to winter storms in late January and early February that reduced patient access and physician office days in specific U.S. regions. Demand outside of the weather-impacted weeks tracked well with our expectations. We entered Q2 focused on execution and 1 month in have seen a strong start, consistent with expected ordering patterns. In fact, year-to-date, we've seen several weeks where testing volume has exceeded 2025 weekly highs, and this is obviously just over a quarter into the year. A big part of my optimism stems from a review of our sales metrics, which continue to show a broadening of our ordering base. Ordering clinicians were up 15% year-over-year, reflecting continued penetration and engagement within our channel. Our team is executing well, and the results continue to build. Now to ASP. One of the clearest indications that our operating strategy is translating into durable business improvement. We expanded trailing 12-month ASP to $444, up $25 per test or 6% versus last year. Strength in the first quarter was driven by continued progress in revenue cycle management and favorable collections timing. We've now delivered 12 consecutive quarters of increasing trailing 12-month ASP and view this metric as the most reliable indicator of progress as it smooths the variability associated with accrual accounting and timing of collections. Overall, we're encouraged by continued improvement in our underlying reimbursement. It reinforces that we're investing in the right processes and the right tools to drive sustainable ASP expansion over time. In the first quarter, we continue to advance our processes around innovation and remain on track with our development priorities. We've been deliberately building the R&D to commercial muscle to deliver a dependable cadence for new products with the objective of launching approximately 1 product every 12 or so months to our clinician base. Our next key priority is an offering for myositis, our first new stand-alone product since 2020, currently targeted for commercialization in early 2027. This is among the most requested diagnostic need within our channel and will fit well with our commercial reach. Myositis is an autoimmune disease that can present in many forms, but often causes chronic muscle inflammation, progressive weakness or rapidly progressing interstitial lung disease. Left untreated, it can lead to irreversible damage that extends beyond the muscles to vital organs. And in the most severe forms, this results in complications leading to complete loss of lung function or even death. The testing dynamic for myositis is similar to connective tissue disease, where specifically with early disease, symptomatic presentation is ambiguous and the differential is broad. While roughly 100,000 patients in the U.S. are affected by the disease currently, we believe this number dramatically underrepresents the true disease prevalence given the number of patients that ultimately go undiagnosed due to inadequate tests in the market. We believe the patient population under evaluation for myositis is many times this number. While most clinicians rely on conventional testing today, the vast majority of them lack confidence in those results. We're developing a comprehensive offering that will bring clarity to this population that clearly needs a better solution. We are also excited about our scientific visibility to start 2026. At Autoimmunity 2026, a key autoimmune conference this month in Prague, Exagen had 9 abstracts accepted, including several tied to our myositis research and continued evidence generation across the AVISE portfolio. We've also had 2 manuscripts accepted for publication related to our research in myositis and SLE. Those should be out for publication later this month as well. Our progress reflects the rigor, quality and practicality of the work our clinical team is driving. Looking ahead, we are reaffirming our full year 2026 revenue guidance of $70 million to $73 million. We're incredibly pleased with the start to 2026 while working to build successive quarters and ultimately years of profitable growth. We remain focused on our priorities and delivering consistent execution. To close, I want to thank our team. The quality of this organization continues to improve and the solid results we're delivering are the product of real collaboration across every function. I am grateful for the tremendous energy, the effort and the high character that our people bring every day in service of autoimmune patients and clinicians. With that, I'll turn it over to Jeff for additional comments on the financials.
