People with the common blood type O express neither the A nor B antigen, and they are perfectly healthy. Numerous associations have been made between particular ABO phenotypes and an increased susceptibility to disease.

abo血型系统是人类最早认识也是最为重要的血型系统。abo血型由红细胞膜上的不同抗原所决定，与人类输血时发生的溶血反应密切相关，具有重要的临床意义。abo抗原也存在于牛、羊和一些猿类等其他动物体内 [1] 。

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] For human blood transfusions , it is the most important of the 47 different blood type (or group) classification systems currently recognized by the International Society of Blood Transfusions (ISBT ...

2023年9月9日 · This activity reviews the ABO blood group system, highlights complications of ABO incompatibility, and emphasizes the appropriate selection of blood products by the interprofessional team-based on ABO blood typing.

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

2023年11月28日 · Type AB: Has both A and B antigens, but no anti-A or anti-B antibodies. Known as the universal recipient. Type O: Has no A or B antigens, but both anti-A and anti-B antibodies. Known as the universal donor. The Rh factor is another critical component of blood typing.

2025年3月31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. Persons may thus have type A, type B, type O, or type AB blood.

2018年8月1日 · The ABO Blood Group System is the foundation of everything we do in Transfusion Medicine. If you are wondering how we test patients and donors to determine their ABO type, this quick blog post is for you.

The ABO gene and its 7 coding exons give rise to one of two principally different glycosyltransferases. The A glycosyltransferase (GTA) catalyzes the addition of a donor substrate, UDP-N-acetylgalactosamine, to an acceptor substrate known as the H antigen.

There are four common blood groups in the ABO system: O, A, B, and AB. The blood groups are defined by the presence of specific carbohydrate sugars on the surface of red blood cells, N-acetylgalactosamine for the A antigen, and D-galactose for the B antigen.
