Employing more than 70,000 people worldwide, the company’s mission is to improve health and improve lives by delivering world-class diagnostics, accelerating the availability of innovative medicines to patients, and using technology to change the way care is delivered.

Labcorp typically processes tests on more than 3 million patient specimens per week and supports clinical trial activity in approximately 100 countries through its industry-leading central laboratory business, generating more safety and efficacy data to support drug approvals than any other company.
