ABO血型系统

ABO Blood Group System

A classification system based on the presence or absence of antigens on the surface of red blood cells, determining blood compatibility for transfusion. / 基于红细胞表面抗原的有无对血型进行分类的系统，用于确定输血兼容性。

Main parameters and performance indicators

Antigen A: Present on red blood cellsAntigen B: Present on red blood cellsAntigen H: Precursor antigenPhenotype: Observable blood type (O, A, B, AB)Genotype: Genetic makeup (e.g., IAIA, IAi)Allele Frequency: Proportion of genetic variants in a population
