Corrected Platelet Count Increment
To evaluate the effectiveness of platelet transfusion
Purpose:
Pre-transfusion platelet count performed
Post-transfusion platelet count performed in 1 hour
Calculation:
CCI = post count – pre count   x   body surface area (m2)
          # platelets/unit x 1011       
Normal CCI:
7500 x 1011/m2
