Platelet apheresis yield is directly proportional to the donor preapheresis platelet count.
The relationship between the preapheresis platelet count on day 15 and the platelet apheresis yield is shown for donors treated with placebo (○, n = 65), 1 μg/kg PEG-rHuMGDF (▪, n = 23), or 3 μg/kg PEG-rHuMGDF (●, n = 22); r = 0.92.
