Effects of serial neutrophil transfusions on the absolute neutrophil count of the recipients.

The peripheral blood PMN count of the patients receiving transfusions was determined immediately before transfusion, 1 hour following transfusion, and the morning following transfusion (approximately 12 hours posttransfusion). Data represent values from patients receiving serial daily transfusions for at least 7 days (n = 10) and are expressed as mean ± SD.
