AB Positive is one of the eight main blood types in the ABO blood group system. It is characterized by the presence of both A and B antigens on the surface of red blood cells, along with the Rh factor, which makes it positive. This blood type can receive blood from all other types, making it a universal recipient. Individuals with AB Positive blood can donate to other AB blood types but can only receive from all blood types. This unique compatibility is important in medical situations, such as blood transfusions and organ transplants, where matching blood types is crucial for patient safety.
