pt ordering availability for 2018 will be announced in ashi insights in december.


ASHI is pleased to announce the 16th year of its comprehensive proficiency testing program

Our 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.


• The PT program is designed to fully meet the latest ASHI standards for laboratory accreditation.


• A user-friendly data submission web site features easy results entry.


• There is international participation by laboratories in 21 countries.


• Current survey categories include: HLA Typing, Engraftment Monitoring, and Antibody Screening/Identification and Crossmatching. The HLA-B27 Detection survey is now offered within the HLA typing (HT) survey using the HT samples.


• To reflect routine clinical testing, results for Class I and Class II typing, or for antibody

identification and crossmatching, are reported using the same samples during the HT and

AC surveys, respectively . Whole blood samples are provided for both typing (HT survey) and crossmatching tests (AC survey).


• Cells provided for crossmatch are typed for HLA-A, B, C, DRB1, DRB3/4/5, DQA1, DQB1, DPA1, and DPB1.


• The AC and AT surveys include antibody identification by solid phase testing of complement fixing antibodies. The surveys also include the option to report antibodies against Angiotensin IIType 1 Receptor (AT1R) as an ungraded, educational challenge.


• Modular configuration of the surveys provides flexibility and cost savings. The “AT” module in the AC survey for antibody identification alone (without cells for crossmatching) provides additional cost savings for those laboratories that do not require crossmatch proficiency testing.


• HLA typing (HT) survey is for serologic, low resolution and/or high resolution typing. Samples have included new alleles and additional sequencing of non-traditional exons is performed by recognized experts in the field to confirm the correct results.


• Summary Reports and concurrent individual Performance Reports present data in a concise and informative fashion, with emphasis on the educational goals of the ASHI Proficiency

Testing Program.


• 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. Due to the low number of participants, the HLA Class II Antibody Identification by Serology (CDC or AHG) will no longer be an accepted analyte.
