Patient's question:
If all other indicators are checked and found to be, it is just that the blood test shows positive blood. What does this mean! In this case, does it mean there is a disease in the blood?Doctor's answer:
The human blood group system consists of more than twenty blood group systems, among which the ABO and Rh blood group systems are the two most closely related to human blood transfusion. When a person's red blood cells have a D blood group substance (antigen), it is called Rh positive and is represented as Rh(+). When the D antigen is absent, it is called Rh negative and is represented as Rh(-).
