Founded in 1967 by Dr. Paul A. Brown, the company began as Metropolitan Pathology Laboratory, Inc. in New York City, later MetPath. Dr. Brown observed the costly, slow nature of diagnostic testing by hospitals. This insight led him to establish an independent, centralized laboratory model, providing efficient, affordable services.

Quest Diagnostics serves diverse customers, including patients, healthcare professionals, hospitals, and employers. Its vision focuses on empowering better health through diagnostic insights, striving to make quality information accessible and affordable. This commitment aims to improve patient outcomes and enable informed healthcare management.
