Panda blood type refers to Rh-negative blood, which is commonly known as panda blood type because it is very rare like a panda. There are two types of blood types in normal people, one is ABO type and the other is Rh blood type, because Rh blood type is another newly discovered blood type in clinical practice after the discovery of ABO blood type research, which is also a very complex system. Therefore, the monitoring of blood types is now monitoring these two blood types, and if there is a transfusion of Rh blood type incompatibility, it may also lead to the loss of the patient’s life. If there is a Rh mother and child blood type incompatibility pregnancy, there is a risk of stillbirth, premature birth and neonatal hemolysis. rh blood type is further divided into Rh negative blood and Rh positive blood, while Rh negative blood is very rare. Rh negative blood is because there is no RhD antigen in human red blood cells, so the blood test is indicated by Rh negative, which is what we commonly call panda blood.
