Blood type B Rh positive, it is a normal blood type. The blood group systems commonly used in clinical practice are the ABO blood group system, and the Rh blood group system. It is two different blood group systems, both of which are clinically important. the ABO blood group system includes blood type A, blood type B, blood type O, and blood type AB, so blood type B is just one of the blood types, and is also a common blood type in clinical practice. For Rh blood type usually has to be divided into Rh negative and Rh positive, and the majority of people in China have positive Rh blood type. According to statistics, Rh-negative blood types are extremely rare among Han Chinese, so people with Rh-negative blood types are called panda blood, so Rh-positive blood types are also common in the clinic, and for transfusion patients are required to check ABO blood types and Rh blood types.
