Effect of platelet dose on the 1-hour posttransfusion platelet count increment for test and reference platelet transfusions.

The 1-hour posttransfusion count increment vs platelet transfusion dose is shown for all on-protocol (test and reference) transfusions in cycle 1. Equal doses of test and reference platelet products resulted in comparable 1-hour count increments (P = .53) over the range of platelet doses transfused. The regression lines for test and reference platelet transfusions appear superimposed.
