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.​​​

NIOSH Requests Feedback on its Manual of Analytical Methods

NIOSH is preparing to develop a new edition of the NIOSH Manual of Analytical Methods (NMAM) and has issued a survey to collect user input. NIOSH’s goal is to make NMAM more user-friendly and to ensure the publication better meets the needs of users.  NIOSH encourages AIHA PAT Programs participants to take the new survey to assist the agency in this endeavor.
