Equalis is a provider of external quality assessment for clinical laboratory investigations based in Sweden. We are also involved in education, standardisation and other quality improvement projects concerning laboratory medicine and other diagnostic disciplines in the field of health care.

Clinical laboratory investigations are commonly used as a basis for diagnosis, monitoring  and treatment. It is of great importance that the results produced are of the best quality and are comparable. The laboratories that perform the investigations need to have a reliable system for quality surveillance, in which external quality assessment plays an important part.
