The primary mission of AIHA Proficiency Analytical Testing Programs is to assist participants in pursuing excellence in laboratory services through external quality control program assessment and to promote the practice of proficiency testing both nationally and internationally.

AIHA PAT Programs provide participants with the opportunity to improve and refine the analytical skills of their staff, while testing new procedures or training different analysts.  These programs, which are open to any interested participants, allow a participant to demonstrate their ability to correctly analyze samples in the workplace and the environment.​​​
