Blood donors who weigh at least 130 lbs (59 kg) and have a haematocrit of at least 40 V per cent can donate 2 units of blood, from which a 360-ml volume of red blood cells (RBC) can be isolated. This study was carried out in seven healthy male blood donors to assess the restoration of the RBC volume 1 month following a 2-unit RBC apheresis procedure.
RBC volumes were measured prior to donation and 4 weeks after the 2-unit RBC apheresis procedure without oral iron supplementation.
Four weeks after the removal of 2 units of RBC from the male donors not supplemented with oral iron, the RBC volume was restored to 92% of the precollection value. The 360-ml volume of RBC collected represented 12-19% of the donor's original RBC volume.
Male donors can safely donate 2 units of RBC and will restore a mean of 92% of their RBC volume within 1 month without iron supplementation.
体重至少130磅（59千克）且血细胞比容至少为40%的献血者可捐献2单位血液，从中可分离出360毫升的红细胞（RBC）。本研究对7名健康男性献血者进行，以评估在进行2单位红细胞单采程序1个月后红细胞体积的恢复情况。
在献血前以及进行2单位红细胞单采程序且未口服补铁4周后测量红细胞体积。
在未口服补铁的男性献血者被采集2单位红细胞4周后，红细胞体积恢复至采集前值的92%。采集的360毫升红细胞体积占献血者原始红细胞体积的12% - 19%。
男性献血者可安全捐献2单位红细胞，且在不补铁的情况下1个月内平均可恢复其红细胞体积的92%。
