Discover How Blood Type Affects Health

A antigen covers red blood cells, while anti-B antibody is in plasma. A B-antigen antibody targets blood cells.

Group A

Plasma has anti-A antibodies, while red blood cells have B antigen. These antibodies target A-antigen blood cells.

Group B

Type AB blood has red blood cells with A and B antigens. Type AB plasma lacks antibodies to either antigen. Thus, type AB blood can safely accept any ABO blood type.

Group AB

The O blood type has plasma with A and B antibodies but no A or B antigens on the red blood cells. It matches any ABO blood type.

Group O

Rh factor or antigen is found in some red blood cells. Red blood cells with this antigen are Rh positive. Without this antigen, they are Rh negative.

Rhesus Factor

Research shows that O blood types minimize the risk of coronary heart disease. This phenomenon's cause is unknown to specialists.

Heart Disease

According to a small study, people with blood type AB are more likely to have cognitive and memory difficulties, which may increase their risk of dementia.


Type O blood is associated with longer life. Experts attribute this to a lower heart and blood vessel disease risk.
