The American Association for Clinical Chemistry (AACC) - renamed the Association for Diagnostics & Laboratory Medicine (ADLM) in 2023, though 'AACC' remains in wide use - has sponsored the American Board of Clinical Chemistry (ABCC) since 1954. The ABCC is the doctoral-level certifying board that awards the Diplomate of the American Board of Clinical Chemistry (DABCC) credential after a candidate passes its comprehensive written examination. This certification validates expert-level competence in clinical and/or toxicological chemistry and matters for laboratory directors and consultants under the CLIA '88 federal regulations.

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.
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.
The AACC certification examination is structured to evaluate a candidate's comprehensive understanding of clinical laboratory science. It typically comprises multiple sections, each focusing on specific areas such as:
The examination format includes multiple-choice questions, case studies, and problem-solving scenarios, all designed to assess both foundational knowledge and practical application skills.
Achieving success in the AACC certification examination requires a strategic and disciplined approach to preparation. Candidates are advised to:
Consistent study habits, combined with practical experience, significantly increase the likelihood of success in the certification examination.
Obtaining the AACC certification offers numerous benefits for clinical laboratory professionals, including:
The certification serves as a valuable asset, distinguishing professionals in a competitive job market and affirming their dedication to quality in laboratory medicine.
Maintaining the AACC certification necessitates ongoing commitment to professional growth and adherence to ethical standards. Certified professionals are typically required to engage in continuing education activities, such as:
These activities ensure that certified individuals remain at the forefront of advancements in the field and continue to provide high-quality laboratory services.
The American Association for Clinical Chemistry Certification represents a significant milestone in the professional journey of clinical laboratory scientists. It not only validates their expertise but also underscores their commitment to excellence and continuous improvement.
Through rigorous examination and adherence to high standards, certified professionals contribute meaningfully to the accuracy and reliability of laboratory diagnostics, ultimately impacting patient care and outcomes.
For those aspiring to improve their careers and make a lasting impact in the field of clinical laboratory science, pursuing the AACC certification is a commendable and rewarding endeavor.
