Health starts with knowledge

Laboratory tests are key to understanding how your body is working. Test results help doctors make an accurate diagnosis, manage conditions, and track recovery progress. Each year, we perform more than 20 million diagnostic tests, from routine blood draws to highly complex analyses at the genomic level. Because our labs are part of the Corewell Health system, we provide you and your doctors information and insights to inform the care you’re already receiving.

The largest system in Michigan

Our extensive network (more than 70 outpatient draw sites) and advanced capabilities—including cytogenetics, flow cytometry, and molecular lab testing at our advanced technology laboratories (ATL)—mean that you can get the testing you need, where you need it. We are also accredited by the College of American Pathologists (CAP), ensuring the highest quality standards.
