There are 4 main blood groups (types of blood) – A, B, AB and O. Your blood group is determined by the genes you inherit from your parents. Each group can be either RhD positive or RhD negative, which means in total there are 8 blood groups.
There are four major blood groups determined by the presence or absence of two antigens, A and B, on the surface of red blood cells. 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-).
Sep 15, 2023 · There are eight blood types, divided into four categories: A, B, AB, and O, and whether Rh positive or negative. These types are determined by antigens on red blood cells. Learn what this means.
There are four main blood groups in the ABO group system. Each group is important and we need donors from every group to ensure we have the right blood for the people who need it. Which group you belong to depends on the antigens and antibodies in your blood.
There are four main blood types: A, B, AB and O. Blood bank specialists determine your blood type based on whether you have antigen A or B on your red blood cells. They also look for a protein called the Rh factor.
Nov 28, 2023 · 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.
Jan 12, 2022 · An overview of ABO and Rhesus blood groups including antigens, antibodies and the implications for blood transfusion.
Aug 7, 2023 · Group O – have both anti-A and anti-B antibodies. Fig 1 – Summary of blood types. Rhesus Grouping System. The second most important blood grouping system is based on Rhesus (Rh) antigens. There are many different Rh antigens but only 5 are clinically significant: D, C, c, E, and e.
ABO blood group. ABO is the most important blood group system. Transfusion with ABO incompatible red cells can lead to severe and potentially fatal transfusion reactions. The ABO blood group system contains four different ABO blood groups (see Table 1) and is determined by inherited antigens expressed on red cells (e.g., A or B antigens).
In the ABO system there are four groups: blood group A has A antigens on the red blood cells with anti-B antibodies in the plasma. blood group B has B antigens with anti-A antibodies in the plasma. blood group O has no antigens, but both anti-A and anti-B antibodies. blood group AB has both A and B antigens, but no antibodies.
