Febrile nonhemolytic transfusion reaction

1. The most frequent reaction associated with the transfusion of cellular blood components is a febrile nonhemolytic transfusion reaction (FNHTR).

2. These reactions are characterized by chills and rigors and a 1°C rise in temperature.

3. FNHTR is diagnosed when other causes of fever in the transfused patient are ruled out.

4. Antibodies directed against donor leukocyte and HLA antigens may mediate these reactions; thus, multiply transfused patients and multiparous women are felt to be at increased risk.
