The mandated testing of blood components for infectious diseases, to prevent transfusion-transmitted infections (TTIs), began in the 1950s. Since then, changes in predonation questionnaires and advances in testing techniques have afforded more sensitive and specific tests for pathogens, in addition to allowing earlier detection. Given that these approaches have very low but detectable failure rates, the recent development and implementation of proactive pathogen reduction approaches is the new forefront of TTI prevention strategies. With globalization and the ability of pathogens to evolve rapidly, continuous redefining of testing standards and laboratory techniques is paramount for maintaining a safe blood supply.
传染病血液成分的强制性检测,以预防输血传播感染(TTIs),始于 20 世纪 50 年代。从那时起,献血前问卷的变化和检测技术的进步,除了能够更早地发现感染之外,还提供了针对病原体更敏感和更特异的检测方法。鉴于这些方法的失败率非常低但仍可检测到,因此,最近积极主动的病原体减少方法的开发和实施是 TTI 预防策略的新前沿。随着全球化和病原体快速进化的能力,不断重新定义检测标准和实验室技术对于保持安全的血液供应至关重要。
