概括
在RhD阴性献血者中进行弱D检测的新算法显著减少了检测时间和成本. 这种方法优先测试只有C阳性和/或E阳性样本,提高效率,而不会错过任何阳性病例.
科学领域:
- 血液银行和输血医疗服务
- 免疫血液学 免疫血液学
- 遗传学 是一个遗传学.
背景情况:
- 尽管在其他地方逐步淘汰,但血清学弱D测试在印度仍然是例行程序.
- 这个过程是资源密集型和耗时的.
- 开发了一种新的算法,以优化RhD阴性献血者的弱D测试.
研究的目的:
- 设计和评估一种新的,更有效的算法,用于RhD阴性献血者的弱D测试.
- 在时间和成本效益方面,将新算法与现有协议进行比较.
主要方法:
- 一项观察性研究涉及印度500个RhD阴性献血者样本.
- 将一个新算法 (CcEe表型化,然后是有针对性的弱D测试) 与现有协议进行比较.
- 使用常规管道技术确定RHD类型,弱D状态和CcEe表型;用于弱D负样本的RHD基因定型.
主要成果:
- 新的算法证明了与现有协议的完美一致 (100%一致, κ=1.00).
- 实现了显著的减少:测试时间减少了71.63%,总成本减少了24%.
- 使用拟议的算法,没有错过任何弱D阳性样本.
结论:
- 对于RhD阴性捐赠者,他们既是C,也是E阴性,弱D检测可能会被停止.
- 将弱D测试限制在C阳性和/或E阳性表型上提供了一个时间和成本有效的策略.
- 这种优化的方法适合印度人口,并提高了血液银行效率.

Blood transfusion is a therapeutic measure to restore the blood volume after extensive blood loss due to an accident or a medical procedure. Blood transfusion involves drawing a certain amount of blood from a suitable donor and infusing it into the recipient.
History
The history of blood transfusion dates back to the 17th century, when early attempts were made in animals. In 1818 James Blundell, a British doctor, performed the first successful human blood transfusion. Later in 1900, Karl...

Understanding an individual's blood group is a critical component of transfusion medicine. It ensures compatibility in blood transfusions, organ transplants, and even during pregnancy. Determining these blood groups involves the ABO and Rh blood typing systems, utilizing specific antigens and corresponding anti-sera to identify an individual's blood type.

Human blood is classified into different types based on the presence of antigens on the red blood cell's surface and antibodies in the plasma. Proper identification of blood type is essential for successful blood transfusion. The International Society of Blood Transfusion has identified 38 human blood types based on the surface antigens on the red blood cells. The most common types are ABO, Rh, and MNS blood types.
