Understanding the AACC Certification

What is commonly called the 'AACC certification' is the Diplomate credential (DABCC) awarded by the American Board of Clinical Chemistry (ABCC), a certifying board sponsored by AACC (now ADLM) since 1954. It validates doctoral-level expertise in clinical chemistry and/or toxicological chemistry through a rigorous written examination plus a review of the candidate's education and experience.

Candidates are assessed on both theoretical knowledge and practical application across clinical chemistry, toxicology, and related laboratory science. The certification reflects a professional's dedication to excellence and adherence to the highest standards in laboratory medicine.

  • ✓Review the official AACC exam content outline
  • ✓Take a diagnostic practice test to identify weak areas
  • ✓Create a study schedule (4-8 weeks recommended)
  • ✓Focus on your weakest domains first
  • ✓Complete at least 3 full-length practice exams
  • ✓Review all incorrect answers with detailed explanations
  • ✓Take a final practice test 1 week before exam day

Eligibility and Application Process

To be eligible for ABCC Diplomate (DABCC) certification, candidates need an earned doctorate (PhD, MD, or DO) in the natural sciences or medicine, with acceptable chemical education including graduate-level biochemistry, plus at least five years of relevant experience in clinical or toxicological chemistry after the doctorate, in a setting acceptable to the Board. The application involves submitting academic transcripts, professional references, and documentation of qualifying experience.

Applicants must also demonstrate good moral character and high ethical and professional standing. The Board reviews each application to confirm candidates meet these doctoral-level criteria before they can sit for the written examination.
