A rich history. A bright future.

At CRL, we value each and every sample as a life entrusted to our care.

We are one of the largest privately held clinical testing laboratories in the U.S. With dedicated facilities in North America, we perform hundreds of thousands of tests every day for clients large and small. Our staff of more than 700 associates works around-the-clock to process and report results seven days a week for many of the largest retail, transportation, pharmaceutical, healthcare, and financial service organizations in the world.

From high-complexity molecular diagnostic COVID-19 testing, to our toxicology and general lab testing, our partners are as diverse as the testing we perform. We serve insurers, employers, healthcare providers and their patients, as well as colleges and universities through broad application of corporate and personal wellness, drugs of abuse testing programs, insurance risk assessment, and molecular diagnostics testing.

Our mission isn’t to be the most recognized lab in the world, but to be the most trusted laboratory partner by providing personalized service, accurate testing, rapid turnaround time, and innovative systems and solutions. We place careful focus on the thousands of lives we touch every day, going above and beyond to provide our partners the insights that help them with their most critical decisions. We conduct research, advance our test menu, pursue collaborations, discover new applications for existing data, and hold ourselves to the highest of quality and support standards, uniquely positioning our partners to achieve the best possible outcomes. And we do it all with a human touch.
