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, known as the red blood cell blood group, consists of up to twenty or more blood group systems. 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 referred to as Rh positive, denoted as Rh(+). When the D antigen is absent, it is Rh negative, denoted as Rh(-).
