The B+ blood type should be B, Rh positive blood type, if a person’s blood type test report shows B, Rh positive, it means that the person’s blood type, in the ABO blood type system belongs to B blood type, in the Rh blood type system belongs to Rh positive blood type. Rh positive means that the person’s red blood cells, there is a blood type antigen named Rh, if there is no such blood type antigen, then it is called Rh negative blood type. The ABO blood group system, which is familiar and of concern to everyone, includes blood types A, B, AB and O. The Rh blood group system, which not many people know about, is the same as the ABO blood group system, and is a method of classifying blood groups. So far, there are many ways to classify human blood group systems, but the two blood group systems mentioned above are the ones found to be more closely related to medicine.
