Platelet Cross Match

As an adjunct to HLA-matched platelet pheresis, we offer platelet screening and platelet cross matching to supply compatible single donor platelet pheresis to the patient who has become refractory to random donor platelets as well as stock platelet pheresis. Immune destruction of platelets can occur in patients with selected hematologic disorders (leukemia, systemic lupus erythematosis, and other collagen-vascular diseases). In vitro antibody screening tests are employed to detect the presence of these antibodies in patient (or donor) sera. Screening tests for antibodies to platelets must incorporate a sufficient number of platelets to facilitate the detection of most commonly encountered HLA or platelet specific antibodies.
