ABO systemn.（名词）- A classification system for human blood that identifies four major blood types based on the presence or absence of two antigens, A and B, on red blood cells. The four blood types (A, B, AB, and O, in which O designates blood that lacks both antigens) are important in determining the compatability of blood for transfusion.ABO血型分类法：一种人类血型分类方法，以红血球上有无A和B两种抗原而分为四种血型。这四种血型（A型，B型，AB型和O型，其中O型意指同时没有A，B这两种抗原）在决定输血时，看其是否相容是至关重要的
