In the past two decades, health services in the developed world have directed much resource toward improving the safety of the blood supply. Blood is collected, tested, and processed within a carefully controlled environment, and quality is assured by rigorous donor selection procedures and increasingly sensitive and sophisticated testing for transfusion-transmitted pathogens. Additional safety strategies implemented by some blood services include leukocyte reduction, bacterial screening, and pathogen inactivation. Thus, the transfusion chain from the donor to the point of issue from the blood center is highly regulated and secure, and transfusion-transmitted infection is an increasingly rare event.
在过去二十年中，发达国家的医疗服务将大量资源用于提高血液供应的安全性。血液在精心控制的环境中采集、检测和处理，通过严格的献血者筛选程序以及对输血传播病原体越来越敏感和精密的检测来确保质量。一些血液服务机构实施的其他安全策略包括白细胞去除、细菌筛查和病原体灭活。因此，从献血者到血液中心发放点的输血链受到高度监管且安全可靠，输血传播感染事件越来越罕见。
