2023年3月14日 · There are eight blood types included in the ABO and Rh blood group systems: A positive (A+), A negative (A-), B positive (B+), B negative (B-), AB positive (AB+), AB negative (AB-), O positive (O+), O negative (O-).

2024年1月16日 · Doctors need to take into account both ABO and Rh when considering blood types. This means there are eight main blood types in the ABO/Rh blood group system. Some are more common than...

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.

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.

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.

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.
