In 1967, a medical residency student founded a laboratory company in a two-bed room apartment in New York City to pursue a bold vision: deliver innovative and quality laboratory testing for less money. Today, Quest Diagnostics is the world’s leading provider of diagnostic information services, providing thousands of diagnostic information services used by one in three American adults every year.
Quest Diagnostics empowers people to take action to improve health outcomes. Derived from the world's largest database of clinical lab results, our diagnostic insights reveal new avenues to identify and treat disease, inspire healthy behaviors and improve health care management. Quest annually serves one in three adult Americans and half the physicians and hospitals in the United States, and our 45,000 employees understand that, in the right hands and with the right context, our diagnostic insights can inspire actions that transform lives.
