AACC’s Lab Tests Online is the premier online patient resource on lab testing. Developed in collaboration with 16 other laboratory associations, Lab Tests Online effectively educates patients and their loved ones about their lab tests.

The site is used regularly by laboratorians, physicians, and other medical professionals who need to quickly confirm their understanding of a test or who seek help in talking about testing with their patients. Lab Tests Online has been translated and adapted by 16 partner sites around the globe.
