Background: The present study was planned to compare of pre and post donation hematological parameters in healthy donors by plateletpheresis. Also to assess the platelet yield following plateletpheresis procedure with its correlation to pre donation platelet count.
Methods: This is a retrospective cross-sectional study carried out in the Blood Centre of a tertiary care hospital in Haryana, India between January to December 2022. Plateletpheresis was done on Trima Accel Automated Collection System with ACD‐A as an anticoagulant. The data was collected from the hospital for hematological parameters (Hb, hematocrit, Total WBC count, total platelet count) pre and post donation. Categorical data is presented as frequency, percentage, mean±SD range. Correlation was established between the pre donation platelet count and the platelet yield.
Results: A total of 125 donors were included in the study with majority of the donors 69 (55.2%) in the age group 21-30 years. Mean age of the donors included in the study was 31.58±7.5 years. The levels of hemoglobin dropped from 14.16±0.95 to 13.92±1.002 gm/dl, hematocrit dropped from 41.19±1.33 to 40.91±2.89%, total WBC count reduced from 7.64±1.38 to 7.61±1.36 103/ l and platelet count dropped from 279.5±62.96 to 259.9±58.38 lac/ l. There was a significant drop in the levels of platelet post donation by 7.01% compared to pre donation levels. majority of the donors (44%) had a mean platelet yield 2.49±0.33 with a platelet count between 1.5-2.5x1011/l. The maximum platelet yield was 4.93±0.34 in 6% donors with pre-donation platelet count of >4.5 5x1011/l. A linear significant relationship was established between the platelet count and the platelet yield (r=0.99).
Conclusions: There were significant changes in the pre donation and post donation hematological parameters among the donors. It was concluded that donors with a high pre-donation platelet count can be considered for better platelet yield.
