Abstract

To determine the feasibility of collecting 2 units (450 mL) of red cells per donation by apheresis technology, apheresis red cell collections were compared to whole‐blood donations. Forty blood donors were equally divided between the two study arms on the basis of gender and iron supplementation (650 mg ferrous gluconate/day vs. no supplementation). During the 1‐year study period, the apheresis participants donated 450 mL of red cells three times, and the whole‐ blood donors gave 225 mL of red cells (1 unit of blood) on six occasions. There were no reported side effects during the 102 whole‐ blood donations, whereas symptoms were noted in 83 percent of the 59 apheresis procedures. The most common symptoms were numbness and tingling, which were relieved by a decrease in the plasma‐return rate or by the administration of oral calcium supplements. Seven donors dropped out or were deferred during the study. Two whole‐blood donors left with medical problems unrelated to the study, one apheresis donor and one whole‐blood donor dropped out of the study because of excessive fatigue, and three non‐iron‐supplemented whole‐blood donors had unacceptably low hematocrit levels. By the end of the study, 70 percent of the apheresis donors considered the procedure acceptable, 15 percent were undecided, and 15 percent thought it was not acceptable. As measures of iron balance, the serum ferritin and the red cell zinc protoporphyrin:heme ratios were significantly more abnormal in the non‐ iron‐supplemented donors than in the iron‐supplemented donors. However, there were no differences in iron balance according to the donation method. 1993 AABB
