血型是基于红细胞表面上某些抗原的存在或缺失而进行分类的。主要的血型系统包括ABO系统和Rh系统。以下是简要介绍:
ABO血型系统:
- A型:个体的红细胞上有A抗原,血浆中含有抗B抗体。
- B型:个体的红细胞上有B抗原,血浆中含有抗A抗体。
- AB型:个体的红细胞上有A和B抗原,血浆中不含抗A或抗B抗体。AB型被称为普通受体,因为他们可以接受任何血型的血液。
- O型:个体的红细胞上没有A或B抗原,但血浆中含有抗A和抗B抗体。O型被称为普通供体,因为他们可以向任何血型捐献血液。
Rh血型系统:
- Rh阳性(Rh+):个体的红细胞上有Rh抗原。
- Rh阴性(Rh-):个体的红细胞上没有Rh抗原。
在提及血型时,人们会同时指出ABO血型和Rh因子。例如,血型为A阳性的人具有A抗原和Rh抗原。
除ABO和Rh系统外,还有其他较小的血型系统,包括各种抗原和抗体。这些在常规血型检测中较少被测试,但在某些医学情况下可能很重要。
