National Academy of Clinical Biochemistry

AACC’s National Academy of Clinical Biochemistry (NACB) is a professional association of doctoral-level scientists who are active in the field of clinical biochemistry. The academy is dedicated to advancing the science and practice of laboratory medicine by:

  • Developing, maintaining, and publishing Laboratory Medicine Practice Guidelines (LMPGs).
  • Developing and supporting educational programs for laboratory professionals, clinicians, other healthcare professionals, and the public.
  • Promoting scientific research in laboratory medicine.
  • Serving as the scientific advisory group to AACC.

Founded in 1976 as a separately incorporated not-for-profit organization, NACB merged with and became the academy of AACC in 2006.

Laboratory Medicine Practice Guidelines

Laboratory Medicine Practice Guidelines provide recommendations for best practices on using clinical laboratory tests to diagnose, monitor, and optimize care of patients with various specified disorders.

To date, NACB has developed and maintained numerous LMPGs in collaboration with other professional organizations based on review of evidence and expert consensus. These practice guidelines cover a wide range of topics, from diabetes to tumor markers, to emerging cardiovascular disease and stroke risk factors.

The two newest practice guidelines that NACB is working on will address pain management and human chorionic gonadotropin testing.

NACB Scientific Shorts (formerly called NACB Blog) is a blog where clinical laboratory professionals can discuss contemporary laboratory issues and practice—from molecular pathology and genetics to patient safety—and, where possible, you can present solutions and best practices.

Join in the Scientific Shorts discussion.

You can also stay updated on NACB’s activities through the academy’s bi-annual newsletter, NACB News and Views.


Through its annual awards program, NACB celebrates outstanding research and service contributions to the field of laboratory medicine.

These awards recognize achievements that colleagues have made over the course of their careers, as well as high quality abstracts accepted for presentation at the AACC Annual Meeting & Clinical Lab Expo.
