Platelets - Apheresis Leukoreduced (Single Donor Platelets)
Apheresis platelets are harvested from one individual donor during an automated collection procedure. A unit should contain platelets equivalent to 6-8 units of platelet concentrate. The volume of plasma in each unit varies from 200-400 ml. Apheresis platelets are used to limit exposure to multiple donors, and help prevent alloimmunization in those patients requiring multiple platelet transfusions. In addition, all pheresis products have had bacterial testing performed. Platelets can be enhanced by being Irradiated and CMV Negative.

Platelets - Apheresis Leukoreduced, HLA Matched
HLA-matched apheresis platelets are used for patients requiring platelet transfusion who are refractory to platelets from unmatched donors. Provides platelets to patients who are refractory to random donor platelets. May decrease transfusion reactions caused by alloimmunization.

Platelet Apheresis, Platelet Crossmatched
As an adjunct to HLA-matched platelet pheresis, we offer platelet screening and platelet cross matching, in order 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.

Platelet Apheresis, Washed
Platelets can be washed with normal saline or saline buffered with ACD-A or citrate, using manual or automated methods. Washed platelets must be used within 4 hours of preparation.

Platelets - Apheresis, Leukoreduced, Directed Donor
Directed-donor apheresis platelets are collected from a single donor, often a family member, referred by the recipient. A unit should contain platelets equal to 6-8 units of platelet concentrate. The volume of plasma in each unit varies from 200-400 ml. Platelet transfusion from family member donors are used for patients refractory to random-donor platelet transfusions, even when the HLA types of donor and patient are unknown. May decrease transfusion reactions caused by alloimmunization. Directed Donor, platelet apheresis can be enhanced by being Irradiated and CMV Negative.
