Great Lakes Diagnostics

Great Lakes Diagnostics was a medical technology company specializing in the development and manufacture of rapid diagnostic test kits for point-of-care and clinical laboratory use. The company's core expertise lay in immunoassay technology, particularly for the detection of infectious diseases and women's health markers. Its flagship products included rapid tests for Strep A and pregnancy, which were widely utilized in physician offices and clinics to provide immediate results. Founded in 1986 and headquartered in Michigan, the company was a key early player in the rapid diagnostics market. In 2002, it was acquired by Inverness Medical Innovations (now part of Abbott Laboratories) as part of a strategic expansion into the professional diagnostics sector.
