A febrile non-hemolytic transfusion reaction is defined as a rise in temperature greater than 1 o C or 1.8 o F from a pre-transfusion level of not lower than 37 o C or 98.6 o F when no other explanation for the fever exists. 11 Transfusion Rates Transfusion rates vary with the patient s clinical condition.

transfuse does not depend on compatibility test results and, instead depends on an evaluation of the patient s need for transfusion (Salama et al, 1992; Garratty & Petz, 1993; Petz & Garratty, 2004). Examples of patients denied transfusion in spite of clear indications have been reported by Conley et al (1980, 1982).
