If you mix blood from two people with wrong blood types, the antibodies in the blood of the person receiving the transfusion will fight the cells of the donor’s blood, resulting in a potentially fatal toxic reaction. People with O negative blood often wonder how rare their blood is since it is always in demand by hospitals and blood centers. Due to the its versatility for transfusions, it is in high demand. Universal Red cell donor has Type O negative blood. What of population has O negative blood type Only 7 of the population have O negative blood. Generally, AB-negative is considered to be the rarest blood type. Also, Rh - negative blood is given to Rh - negative patients, and Rh - positive or Rh - negative blood may be given to Rh - positive patients. There are dozens of blood typing systems, but the most used are the ABO and Rh systems, which provide the eight basic blood types.

If you have type B blood, you can receive type B or type O blood. Use the interactive graphic below to learn more about matching blood types for transfusions.

If you have type A blood, you can receive type A or type O blood.

If you have type O blood, you are a universal donor and can donate blood to anyone.

If you have type AB blood, you are a universal recipient and can receive blood from all donors.

There are an additional 61 known antigens in the Rh system. When we separate the ‘O’ types into ‘negative’ and ‘positive’ we find that ‘O’ negative (the universal donor blood) constitutes less than 7 of the worlds population.

Blood type ‘O’ is the most common of the blood groups. However, this is just a very basic labeling of our blood types and each type has further subdivisions. Therefore, there must have been some manner of intervention giving rise to Rh-negative blood groups. The system is based on antigens that are either present or absent on the surface of a person’s red blood cells.īecause of compatibility issues between blood groups, it’s critical that appropriate donors are matched with a person who needs a blood transfusion: In general, there are four main blood types or blood groups A, B, AB, and O with both Rh negative and Rh positive variants for each group.

The ABO blood group system groups human blood into four main types: The ABO blood type system and how it affects donating or receiving blood
