American Board of Clinical Chemistry

The American Board of Clinical Chemistry (ABCC) is a not-for-profit organization, incorporated in 1950, devoted to certification of individuals with doctoral level degrees in the practice of clinical chemistry, toxicological chemistry, and other clinical laboratory medicine disciplines. In purpose, function, and organization the ABCC is analogous to the certifying boards in various medical specialties. The aim of the Board is to serve the public interest and advance the science by establishing standards of competence for those who practice clinical laboratory medicine, and to certify as Diplomates those qualified specialists who comply with the requirements of the Board.

Applications for the August 2026 exam cycle are now open from March 9 through May 7, 2026. Visit "Application Guidelines" for details on educational and professional requirements. As a reminder, ABCC is delivering all exams in-person at a Kryterion Testing Center.

Testimonials

Agger, Sean PhD_20110705_01

Becoming board certified in clinical chemistry has given me the opportunity to move into a high profile position at my institution. The credentials have also provided me with opportunities to moonlight as a forensic toxicology director and consult on project that would have otherwise been out of reach. I would highly recommend becoming a board certified Diplomate.

The ABCC credential speaks for itself—it indicates a level of knowledge, training, and expertise in our field. People with a variety of educational backgrounds may serve as clinical consultants, and board certification provides a common baseline. In my current position, I provide consultation to clients from across the United States, and board certification helps define my role.
