| Abstract: | Pre- and post-donation haematological values were measured in 112 donors undergoing plateletpheresis using Haemonetics PCS machines. We found significant differences between pre- and post-donation means for males (M) and females (F) for haemoglobin (M: pre 14.73 g/dl, post 15.25 g/dl; F: pre 13.57 g/dl, post 13.94 g/dl), haematocrit (M: pre 0.418, post 0.431; F: pre 0.389, post 0.4), total protein (M: pre 73.1 g/1, post 66 g/1; F: pre 72.2 g/1, post 63.7 g/1) and albumin (M: pre 42.2 g/1, post 38.5 g/1; F: 41.4 g/1, post 37 g/1). Significant differences were also seen for platelet count (pre 258.6 times 109/1, post 229.2 times 109/1), total white cells (pre 5.3 times 109/1, post 5.55 times 109/1) and neutrophils (pre 3.15 times 109/1, post 3.33 times 109/1), but there were no differences between males and females. This information was of value in establishing post-donation reference ranges which could be utilised when reviewing the suitability of donors for subsequent donations. |
