Rh blood typing generally refers to the testing of the D antigen in the Rh system, and is categorized as Rh-positive or Rh-negative depending on whether or not the patient’s red blood cells carry the D antigen. So Rh (D) positive is just a blood typing, not a pathological significance, no need to worry. RH(D) blood type is one of the human blood types, and everyone has RH blood type, just like everyone has different ABO blood types.RH blood type is clinically categorized into two main groups. Those that contain the D antigen are RH-positive and those that do not are RH-negative. In our population, RH-positive people account for a large proportion of the population, RH-negative people are very few, belonging to the extremely rare blood type. In clinical application, RH blood group is of great significance in clinical blood transfusion and obstetrics. if RH negative patients are transfused with RH positive blood by mistake, serious hemolytic reaction is likely to occur, and RH negative women are prone to severe hemolytic reaction when giving birth to a second child. Therefore, RH-negative women must take pregnancy tests on time during pregnancy and actively cooperate with their doctors during labor. If you need to know your RH blood type, you can take a blood test at the hospital.
