AACC is an international scientific/medical society of clinical laboratory professionals, physicians, research scientists and other individuals involved with clinical chemistry and related disciplines. Founded in 1948, the society has 10,000 members and is headquartered in Washington, DC.

Our vision is to provide leadership in advancing the practice and profession of clinical laboratory science and its application to health care.  We are best known for the journal Clinical Chemistry, the most cited in the field, and for our annual meeting, the world's largest lab conference with about 17,000-19,000 registrants from more than 100 countries.  AACC offers many programs that address the scientific, clinical, technical, and management challenges facing laboratory professionals. 

AACC spearheaded the development of Lab Tests Online, a unique consumer education program, with the cooperation of a number of professional societies and industry sponsors.  Attracting more than one million visitors a month, the US site is the center of a global network that provides high quality information on lab tests in a number of different languages and adapted to local medical practices. 

The association is divided geographically into 22 local sections which provide local conferences and networking opportunities throughout the U.S.  In collaboration with sister societies in other countries, AACC hosts conferences in other regions of the world.
