2026 PT Ordering

The PT Data Center is able to accept PT orders for 2026. Laboratories interested in participating in the ASHI PT Program should first review the 2026 PT Shipping Schedule and 2026 PT Brochure for additional details on PT surveys and challenges to determine which options might meet your needs. Additional information and documents are available in the General Program Information tab below. Contact the PT Program Manager at chartman@ashi-hla.org for help in placing PT orders.

PT Result Entry Webinars

In Spring 2024, the PT Committee presented 3 webinars to provide step-by-step guidance to participating laboratories on entering PT results and to answer questions about how to access the PT Data Center. Use the links above for more information on the EMO (Engraftment Monitoring) survey, the HT (HLA Typing) survey, and the AC (Antibody Screening/Identification and Crossmatching) survey.

Submitting PT Orders

For laboratories that submitted orders in previous years, PT module quantities are pre-filled based on last year's order to simplify the ordering process. To modify an order, or to modify the CAP information (for labs in the U.S. or Canada), click the Edit Order button.

“We appreciate the ASHI PT program because the samples that we receive closely mimic the sample types we get from our patients. Our laboratory appreciates the educational nature of the Summary Reports and we also store the PT materials to use for laboratory validations and ongoing competency assessments.”
