LabCorp has more than 25,000 employees and offers more than 4,400 clinical tests ranging from routine blood analyses to the most sophisticated molecular diagnostics. LabCorp tests more than 360,000 specimens daily for over 220,000 clients nationwide. LabCorp operates a nationwide network of 35 primary testing locations, more than 1,300 patient service centers, and routine testing is the cornerstone of the company's industry-leading national network. That delivery and service network makes it possible for LabCorp to easily offer an extensive esoteric testing portfolio and groundbreaking technologies to a broader audience, including medically important genomic tests.
