2025年2月19日 · The four major blood groups are based on whether or not you have two specific antigens — A and B. Doctors call this the ABO Blood Group System. Group A has the A antigen and B antibody.

2024年1月16日 · Most people use the ABO system to group blood types, and rhesus factor, which is either positive or negative. An individual’s blood type depends on which genes they inherited from their...

2017年8月25日 · The main difference between ABO blood group and RH blood group is that ABO blood group is determined by the presence or absence of A and B antigens on the surface of the red blood cell whereas RH blood group is determined by the presence or absence of D antigen on the surface of the red blood cell.

ABO/Rh refers to the blood type classification system that determines an individual’s blood group and Rh factor, crucial for transfusions. The ABO blood group system is a critical element in human biology, categorizing blood into four distinct types: A, B, AB, and O.

In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (–), creating the 8 most common blood types (A+, A-, B+, B-, O+, O-, AB+, AB-). There are very specific ways in which blood types must be matched for a safe transfusion.

ABO blood group antigens present on red blood cells and IgM antibodies present in the serum. 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]

2022年1月12日 · In this article, the ABO and Rh blood group systems will be outlined, and the guidelines for blood product compatibility will be explained based on the possible interactions between the patient and the transfused blood product.

2023年11月28日 · Blood is either Rh-positive (Rh+) or Rh-negative (Rh-). Combining the ABO system with the Rh factor, there are eight main blood types: The rarity of blood types varies depending on where you live. In the US: Rarest Blood Type: AB-, followed by B- and A-. Most Common Blood Type: O+, followed by A+ and B+.

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.

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.
