This testing is used for patients with evidence of alloimmune platelet transfusion refractoriness, to aid in the selection of HLA compatible platelet units. It is also used to determine whether a patient who is being evaluated for hematopoietic stem cell transplant has antibodies against HLA Class I antigens expressed in potential donors, and aids in donor selection. Please print, complete and submit the Histocompatibility Non- Transplant Test Reqisition Form from the Blood Center of Wisconsin with the specimen and the A-1a Miscellaneous Request.
