Abstract
BACKGROUND
Single-donor platelet transfusion is the preferred therapeutic option for patients with platelet insufficiency and its effectiveness is partly dependent on the yield.
AIM
To determine the platelet yield and predictors of platelet yield in single-donor apheresis.
MATERIALS AND METHODS
This was a five-year review of the data on single-donor apheresis using the Haemonetics Apheresis machine MCS+ at Alex Ekwueme Federal University Teaching Hospital Abakaliki Ebonyi state. Platelet donor related variable of interest included the pre-donation platelet count, donor's blood group, number of apheresis cycles and yield volume. Analysis was done using Graphpad Prism version 9.1.1.
RESULTS
A total of 153 platelet apheresis were studied. The mean (SD) values for pre-donation platelet count, number of cycles, platelet yield and volume of platelet concentrate were 279 ± 47 x 109/L, 6 ± 0.3, 4.5± 0.8 X 10 11/L, and 320 ± 78 mL respectively. In this study, volume of platelet concentrate predicted 61% of platelet yield while platelet count of donor predicted 41%. Neither ABO nor Rh blood groups was a determinant of platelet yield.
CONCLUSION
Pre-donation platelet count and volume of platelet concentrate are important predictors of platelet yield. There is need for proper platelet donor selection.
