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 February 2026 exam cycle are closed. Visit "Application Guidelines" for details on educational and professional requirements. As a reminder, ABCC is delivering all exams remotely.

Testimonials

Being ABCC certified allows me to be confident that I can compete for clinical chemistry/toxicology positions across the country. From a clinical licensing perspective, having ABCC certification was essential to obtaining a Clinical Chemist director license in the State of California. To me, someone with ABCC certification signifies that they are commitment to our profession and have achieved a high level of success.

LABAY HEADSHOT
My main area of practice is postmortem forensic toxicology. Being board certified in toxicological chemistry shows my colleagues, regulatory agencies, and the courts that I also have competence in the interpretation of test results pertaining to living individuals. Also, due to the continuing education requirements associated with this certification, I can better evaluate different case types with confidence that my skill set remains current with the latest clinical laboratory developments.
