And why this incredibly important blood group is particularly essential for accident and emergency departments. So, now you know why demand for O negative blood donations is so high. Rh Negative Blood Types: A-, B-, 0- and AB.

The following are the possible combinations of blood types with the Rh factors: Rh Positive Blood Types: A+, B+, 0+ and AB+. If there is no Rh factor protein, the person is Rh- negative. Unfortunately, however, an O negative recipient can only receive blood from a donor who is also O negative. If the Rh factor protein is present on the cells, the person is Rh-positive. So, if a B positive donor gives you his blood, your immune system will try to eliminate the B antigen of the B positive blood type - because this antigen is foreign to your body.īut if you are given a transfusion from an O negative blood donor, the lack of antigens means your immune system won’t generate a fight response and accepts the blood transfusion. Antigens that, if present in the red blood cells, will cause the immune system to respond.įor example, if your blood type is A positive, it will have both A and RH antigens present. The reason why O negative is such a desired blood group in blood banks is because it lacks three antigens - A, B and Rh.

In fact, this blood type is even considered as the safest option for babies who need blood transfusions – or for instances when a specialised procedure needs to be conducted on unborn babies. In these instances where doctors need to give someone a blood transfusion immediately and can’t afford wait or spend time on checking the blood group of the patient in need – donors with blood type O negative can come to the rescue. This is the main difference between positive and negative blood. In contrast, negative blood lacks the Rh factor on the surface of the red blood cells. Positive blood comprise the Rh factor on the surface of the red blood cells. Which explains why it’s the most preferred blood group for emergency transfusions. Positive and negative blood are the two types of blood classified based on the Rh blood group. That’s because their blood can be transfused to almost any patient in need. Indeed, individuals whose blood type is O negative are known as ‘universal donors’. While only about 7% of the population has O negative blood – people with this blood type have a particularly unique ability to help people in emergency situations.
