Effect of platelet dose on the 24-hour posttransfusion platelet count increment for test and reference platelet transfusions.

The 24-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 24-hour count increments (P = .19) over the range of platelet doses transfused. The regression lines for test and reference platelet transfusions appear superimposed.
