Touching millions of lives

Each day, our 45,000 employees strive to find new ways to empower clinical decision-making and improve patient outcomes. Our services range from routine tests- like cholesterol panels, Pap testing and white blood cell counts - to sophisticated cancer testing, gene-based and molecular testing. We perform diagnostic tests that aid in the diagnosis or detection of, and measure the progress or recovery from a disease. 

Beyond laboratory testing, we offer services to a range of other customers and organizations including physicians, employers and insurers. Thousands of physicians use our information technology expertise to order lab tests, deliver timely test results, share clinical information, and prescribe drugs to patients. Employers rely on Quest to help reduce illegal drug use in their workplace and provide programs to promote wellness and disease prevention. Quest is also the leading provider of risk assessment services to the life insurance industry.
