Diagnostic & Medical Laboratories in the US Industry Data and Analysis
Personalized medicine is reshaping laboratory costs and services, impacting growth and competitive strategies. Demand is rising for laboratories capable of advanced genetic testing, which requires sophisticated technology and specialized expertise in genetic data analysis. Although these tests carry high upfront costs, they can lower long-term healthcare expenses and increase the clinical value of laboratory services. As demand rises, laboratories' operating expenses are climbing, increasing the benefits of consolidation. Mergers enable lab networks to capture economies of scale, invest in new technologies and offer more comprehensive testing menus. While new technologies like point-of-care testing (POCT) present ongoing competitive challenges, industry revenue has grown at a slower CAGR of 0.4% to reach $88.7 billion through 2026, reflecting strong growth earlier in the period. The industry is experiencing a 3.0% gain in 2026 alone, with profit increasing.
