AB Rh positive is a blood type characterized by the presence of both A and B antigens on the surface of red blood cells. This means that individuals with this blood type can receive blood from any ABO group, making them universal recipients. The "Rh positive" indicates the presence of the Rhesus factor, a specific protein that can also be found on red blood cells. People with AB Rh positive blood can donate to other AB blood types but can receive from all other types, including A, B, AB, and O blood types, whether they are Rh positive or negative. This unique compatibility is important in medical situations like blood transfusions and organ transplants.
