HLA-matched platelets are indicated in patients who have become refractory to platelet transfusions due to HLA alloimmunization. Refer to HLA-Matched Platelets Requisition and Administration Procedure (DCS document).
Patient must have HLA typing (HLATX), and HLA Antibody Detection and Identification (HLAIDSO) completed before HLA-matched platelets can be ordered and available for transfusion. If HLA testing is required, turn around time for determination and availability of platelets is approximately 7-10 days. If HLA testing previously completed, turn around time for platelets is 2-3 days.
Refer to Versiti Lab Test Menu for specimen requirements for HLA-AB Low Resolution (2303) and HLA Antibody Identificaion Class I High Resolution (2226)
