The term human blood group systems is defined by the International Society of Blood Transfusion (ISBT) as systems in the human species where cell-surface antigens—in particular, those on blood cells—are "controlled at a single gene locus or by two or more very closely linked homologous genes with little or no observable recombination ...

2025年1月11日 · ABO blood group system, the classification of human blood based on the inherited properties of red blood cells (erythrocytes) as determined by the presence or absence of the antigens A and B, which are carried on the surface of the red cells.

2023年8月3日 · Blood group, also known as blood type, is a category (type) of blood groups based on the presence and absence of blood group antigens in the surface (membrane) of the RBCs, and antibodies on the plasma.

2023年11月28日 · Blood types are a classification of blood based on the presence or absence of specific antigens on the surface of red blood cells. These antigens determine the body’s immune response to foreign substances and are crucial in the context of blood transfusions, organ transplants, and pregnancy.

ABO blood group is the most important blood group system in transfusion and organ transplantation medicine. ABO antigens can be found on red cells, white cells, platelets and many circulating proteins. Transfusion incompatibility can cause acute intravascular hemolysis, renal failure and death.

The ABO blood group system is used to denote the presence of one, both, or neither of the A and B antigens on erythrocytes (red blood cells). [1] .

2023年9月9日 · People can be divided into four main groups (A, B, O, and AB) based on the agglutination patterns of their red blood cells. The ABO blood group system consists of A and B antigens on red blood cells and their corresponding antibodies in the sera of people who do not express those antigens.
