The ASHI PT program is designed to fully meet the latest ASHI standards for laboratory accreditation. The PT program utilizes clinically-based samples to assess a laboratory’s ability to accurately perform its analyses. All surveys are graded using established criteria with oversight by ASHl’s Proficiency Testing Committee. 


ASHI is accepted by the College of American Pathologists (CAP) as an alternative proficiency testing program provider for the HLA Typing, HLA-B27 Detection, Engraftment Monitoring, and Antibody Screening/Identification and Crossmatching surveys. If your laboratory is accredited by CAP, ASHI is able to report your ASHI PT Survey Performance Reports directly to CAP.
