A 50+ year legacy sparked by a need for accessible testing.
In 1967, Paul A. Brown, M.D., founded what would become Quest to fill a gap; a lack of accessible outpatient testing. Our practice has since built on itself, making us an early pioneer in serving patients nationally.
Drawing new insights from billions of data points.
More than 56 billion patient data points allows us to better understand the nuances of the human body - and better serve more people.
Operating at truly national scale.
More than 7,100 access points, the most extensive in the U.S., allow us to serve one third of the U.S. population - and half the nation's physicians - each year.
