blóðflokkun
Blóðflokkun, also known as blood typing, is a method of classifying blood based on the presence or absence of inherited antigens on the surface of red blood cells. These antigens are typically proteins or carbohydrates. The most common and clinically significant blood group system is the ABO system, which categorizes blood into four main types: A, B, AB, and O. Type A blood has A antigens, type B has B antigens, type AB has both A and B antigens, and type O has neither A nor B antigens.
Another crucial blood group system is the Rh system, which determines if an individual is Rh-positive or
Blóðflokkun is vital in medical transfusions. If incompatible blood types are mixed, the recipient's immune system
