Quest Diagnostics 50th Anniversary – Half a Century of Life-Changing Results

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.
