The management of the AIHA Proficiency Analytical Testing Programs (PAT Programs) is committed to the quality of its proficiency testing services to participants and other customers.
The purpose of the PAT Programs is to provide participants with the opportunity to improve and refine their analytical skills while performing various analyses or testing new procedures and to demonstrate proficiency with established test methods. These programs are open to all interested participants.
The objective of these programs is to allow participants to demonstrate their ability to correctly analyze samples by determination of assigned values for quantitative analysis and correct identification for those test items that are qualitative.
