Red cells are the most important and usually the only necessary part of transfused whole blood. Transfusion of concentrated red cells involves several advantages for the recipient (decreased volume load, fewer transfusion reactions, better antianemic effect per unit). The plasma which is separated from whole blood during the preparation of packed red cells can be used for fractionation or for the preparation of platelet concentrates and other special products. The increasing need for blood components makes the substitution of whole blood by packed red cells for transfusion purposes mandatory. The only rare indication for whole blood is fresh blood (i.e. blood up to 48 hours after donation). Red cell concentrates with a hematocrit of 70% are particularly suitable for general use, since the viscosity still allows transfusion without difficulties. With regard to quality and storage time of red cells there is no difference between packed cells and whole blood.
红细胞是输注全血中最重要且通常是唯一必要的成分。输注浓缩红细胞对受者有诸多益处（减少容量负荷、减少输血反应、每单位的抗贫血效果更佳）。在制备浓缩红细胞过程中从全血分离出的血浆可用于成分分离或制备血小板浓缩物及其他特殊制品。对血液成分需求的不断增加使得用浓缩红细胞替代全血用于输血成为必然。全血唯一罕见的适应证是新鲜血液（即献血后48小时内的血液）。血细胞比容为70%的红细胞浓缩物特别适合一般使用，因为其黏度仍允许顺利输血。就红细胞的质量和储存时间而言，浓缩红细胞与全血并无差异。
