The Corrected Count Increment (CCI) and the Increment in Platelet Count after Platelet Transfusion
Purpose: | To measure increase in platelet count after platelet transfusion, in order to see if increase expected is achieved. |
Specialty: | Clinical Laboratory Hematology Oncology |
Objective: | other testing, dosage calculations, dosage adjustments |
ICD-10: | Z51.3, D69 |
Description: | The increment in platelets following platelet product transfusion is directly related to dose given, unless there is increased removal of the transfused platelets. The Corrected Count Index (CCI) is intended to differentiate between immune and nonimmune loss, with a post-transfusion specimen collected 1 hour after the platelet product transfusion. With immune thrombocytopenia there is little increment in the platelet count seen at 1 hour, whereas with nonimmune mechanisms the platelet count at 1 hour is relatively normal. |
