The American Red Cross estimates that less than 7% of the U.S. population have type O-negative blood. Our hospitals, emergency departments, and trauma teams depend on frequent O-negative donations to ensure it’s always available for patients in need.
The rarest of the major blood types in the U.S. population are AB negative (0.6%), B negative (1.5%), and AB positive (3.4%). The most common of the ABO and Rh blood types is O positive. Having Rh negative blood (which is different from Rh null) can be a health concern during pregnancy.
The universal red cell donor has Type O negative blood. The universal plasma donor has Type AB blood. There are more than 600 other known antigens, the presence or absence of which creates "rare blood types."
O-negative blood type is relatively rare. A person with O-negative blood is a universal donor but can only receive blood from the same group. Blood group is determined by the presence of antigen(s) on the membrane of red blood cells.
Blood type O negative (O-) is the universal donor. This means that a person with any other blood type can safely receive your blood. It doesn’t contain any antigen markers that other blood types recognize as not belonging.
If you have O-negative blood, you have something in common with about 7 percent of the US population. Or to put it another way, about 1 in 15 people have O-negative blood. Is that rare? Only about 1 in 67 have B-negative blood, making it rarer. However, the rarest blood type in the world is Rh-null, which is so rare most of us have never heard ...
In the United States, AB-negative is the rarest blood type, while O-positive is the most common. Your blood type is based on genetics and whether it contains certain antigens. While...
Type O negative blood is called a universal donor, meaning that it can be safely given to people with most other blood types and has a low risk of a transfusion reaction. People with type AB positive blood are known as universal recipients, meaning they can be given almost any type of blood safely.
People with blood types O- or O+ can receive your plasma. To maximize your true lifesaving power, O- blood donors are strongly encouraged to donate double red blood cells or whole blood. 7% of the population shares your blood type.
Myth: O Negative blood is the rarest blood type. Contrary to popular belief, O- blood is not the rarest blood type. It is estimated that 7 percent of the population has O- blood type while only 1% of the population has AB- blood.
