Clinical Reference Laboratory

Clinical Reference Laboratory We value each and every sample as a life entrusted to our care. Greater Insights. Better Outcomes.™ And we do it all with a human touch.

CRL was originally founded as Enzyme Technologies in 1979 with our focus on clinical research and development. The name was changed to Clinical Reference Laboratory in 1983 when we began to offer commercial lab testing. Today, CRL has become one of the largest privately held clinical testing laboratories in the U.S., performing hundreds of thousands of tests every day for clients large and small. Our staff works around-the-clock to process and report results seven days a week. We are driven each day to provide the useful insights people need to live healthy, safe, and productive lives. We serve insurers, employers, healthcare providers and their patients, colleges and universities, as well as federal, state, and local government agencies through a broad array of corporate and personal wellness programs, drugs of abuse testing programs, insurance risk assessment, and molecular diagnostics testing. Together with FormFox, the nation’s leading provider of ECCF and electronic workflow solutions, we provide integrated solutions for workplace drugs of abuse testing, occupational health testing, and clinical lab testing services. CRL’s industry-leading turnaround times and state-of-the-art equipment and technology, paired with FormFox’s data management and digital workflow solutions, seamlessly connect all participants. Our mission isn’t to be the most recognized lab, but to be the most trusted laboratory partner by providing personalized service, accurate testing, rapid turnaround time, and innovative systems and solutions. We conduct research, advance our test menu, pursue collaborations, discover new applications for existing data, and hold ourselves to the highest level of quality and client support standards, uniquely positioning our partners to achieve the best possible outcomes.
