概括
在北印度的RhD阴性献血者中,DEL表型很罕见,因此需要进一步研究常规的Rh C/E抗原类型识别. 这一发现对于预防输血与免疫接种至关重要.
科学领域:
- 输血医学 输血医学
- 免疫血液学 免疫血液学
- 血液银行 血液银行
背景情况:
- 较弱的DD变异型的DEL表型无法通过常规血清学检测,需要专门的劳动密集型方法.
- 在献血者中精确识别DEL表型对于预防输血受体的合免疫非常重要.
- 在不同种族的人口中,DEL表型的患病率有很大差异.
研究的目的:
- 为了确定来自北印度的RhD阴性献血者中DEL表型的频率.
- 调查DEL表型与扩展的Rh C/c和E/e抗原配置文件之间的相关性.
- 评估常规Rh C/E类型化作为DEL表型的查策略的潜力.
主要方法:
- 一项前性描述性横截面研究,涉及205名RhD阴性献血者.
- 血液分组使用全自动免疫血液学分析仪进行.
- 用于在血清学上较弱的D阴性样本中检测DEL表型的特殊吸附-化技术.
- 对C/c和E/e抗原进行扩展的Rh表型分析,对所有注册的捐赠者进行.
主要成果:
- 在11934名总捐赠者中,6.2%是RhD阴性.
- 在205名注册RhD阴性捐赠者中,有2名血清学上较弱的D阳性捐赠者.
- 在剩余的203名捐赠者中没有检测到任何DEL表型.
- 扩展的Rh表型检测显示了6.83%的RhC阳性和1.46%的RhE阳性捐赠者.
- 两个弱D阳性捐赠者也表达了RhC抗原.
结论:
- 在研究的北印度人口中,DEL表型的患病率似乎很低.
- 常规的C/E抗原类型测定可能不是一个足够有效的策略来识别DEL阳性个体.
- 建议进行更大规模的研究来证实这些发现,并探索DEL表型的替代查方法.

Blood Types

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.

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.
