Great Lakes Medical Laboratory

Great Lakes Medical Laboratory is a private U.S. clinical reference laboratory providing routine and specialty diagnostic testing services for healthcare providers and patients. The company offers a broad in-house and reference testing menu spanning hematology, chemistry, pathology, cytology, microbiology, molecular testing, toxicology, pharmacogenetics, women's health, STD testing, urine culture, and COVID-19 diagnostics. A core differentiator is its mobile phlebotomy and specimen collection network serving nursing homes, assisted living, homebound patients, rehabilitation facilities, and other care settings. The business appears to operate as a service-based healthcare diagnostics company rather than a therapeutics developer, with revenue generated from laboratory testing and related support services.
