The shelf life of 60,000 units of whole blood and red cell concentrates in the blood center were analysed before delivering to hospitals as well as the transfusion age of 18,000 units in relation to the stock-size and the outdated units. The mean transfusion age of whole blood units and red blood cell concentrates amounted to 11 to 12 days and 16 to 17 days, respectively. The shelf life of blood transfused within 24 hours after collection was 1.6% and 3.8% transfused within 48 hours according to the total number of whole blood and red blood cell concentrates. Washed red cell concentrates were prepared from buffy coat-free resuspended red cell concentrates on an average at the 7th day of storage. A high stock-size of about 1,000 units rather than of 600 units in the blood center increased the shelf life and also the number of outdated units from less than 0.5% up to more than 3%.
对血液中心60000单位全血和红细胞浓缩物在发放到医院之前的保存期限进行了分析，同时分析了18000单位的输血龄与库存规模和过期单位的关系。全血单位和红细胞浓缩物的平均输血龄分别为11至12天和16至17天。根据全血和红细胞浓缩物的总数，采集后24小时内输注的血液保存期限为1.6%，48小时内输注的为3.8%。洗涤红细胞浓缩物平均在储存第7天由无白细胞层的重悬红细胞浓缩物制备。血液中心约1000单位而非600单位的高库存规模增加了保存期限，同时过期单位数量也从不到0.5%增加到超过3%。
