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 is closed. Visit "Application Guidelines" for details on educational and professional requirements and "Exam Cycles and Fees" for timeline. As a reminder, ABCC is delivering all exams in-person at a Kryterion Testing Center.

Jennifer Colby, PhD

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.
