In the United States, AB-negative is the rarest blood type, white O-positive is the most common.
In the U.S., the blood type AB, Rh negative is considered the rarest, while O positive is most common.
Less than 1% of the U.S. population have AB negative blood, making it the least common blood type among Americans. Patients with AB negative blood type can receive red blood cells from all negative blood types.
Of the eight main blood types, people with type O have the lowest risk for heart disease. People with types AB and B are at the greatest risk, which could be a result of higher rates of inflammation for these blood types. A heart-healthy lifestyle is particularly important for people with types AB and B blood.
CHANGES in blood type have been described in a variety of illnesses, usually acute infections or neoplasms.

For example, if someone's Rh factors are both positive, it is not possible for his or her child to have a negative blood type. Only people with at least one Rh-negative factors will have a negative blood type, which is why the occurrence of Rh-negative blood is less common than Rh-positive blood.
There are eight different blood types and each one holds a unique power to save lives. But the most common blood type is O+, accounting for more than a third of all people (37%). This means there is a higher demand for this blood type when it comes to blood transfusions.
One of the world's rarest blood types is Rh- null. It is called the "golden blood". This blood type is distinct from Rh-negative since it has none of the Rh antigens at all.
Is A negative blood rare? Around 8% of donors have A negative blood. In comparison, 30% of donors have A positive blood.
38% of the population has O positive blood, making it the most common blood type. O positive red blood cells are not universally compatible to all types, but they are compatible to any red blood cells that are positive (A+, B+, O+, AB+).
The rarest blood type is Rhnull. Unlike other blood types, people with Rhnull blood have no Rh antigens on their red blood cells. Researchers estimate that just 1 in 6 million people have Rhnull blood.
The oldest of the blood types, Type O traces as far back as the human race itself. With primal origins based in the survival and expansion of humans and their ascent to the top of the food chain, it's no wonder Blood Type O genetic traits include exceptional strength, a lean physique and a productive mind.
O+ blood is very important as a (mostly) universal red blood cell type. This blood type can be used in emergency situations such as traumatic bleeding or other types of emergency transfusions. It is also an important blood type as type “O” patients can only receive type “O” red blood cell transfusions.
Although Rh positive is the most common blood type, having a Rh-negative typing does not indicate illness and usually doesn't affect your health.
Blood is considered Rh-null if it lacks all of the 61 possible antigens in the Rh system. This not only makes it rare, but this also means it can be accepted by anyone with a rare blood type within the Rh system. This is why it is considered “golden blood.” It is worth its weight in gold.
A blood test diagnoses Rh incompatibility. If you become pregnant, your obstetrician will test you to determine if you're Rh-negative. If you're Rh-positive, nothing else happens. If you're Rh-negative and your antibody screen is negative, your provider will give you Rh immune globulin to prevent antibody formation.
Famous Type O personalities: Queen Elizabeth II, John Lennon or Paul Newman.
What's the rarest blood type? AB negative is the rarest of the eight main blood types - just 1% of our donors have it. Despite being rare, demand for AB negative blood is low and we don't struggle to find donors with AB negative blood.
They pack supplies of their own blood
But in order to do an blood transfusion, you need to have a doctor on hand, which is why a Royal Navy doctor accompanies every royal on his or her trip for emergencies.
No association between ABO blood group and longevity was observed by Vasto and colleagues12 in a study on 38 centenarians and 59 healthy controls.
Chances are higher you'll live longer if you have type O blood. Experts think your lowered risk of disease in your heart and blood vessels (cardiovascular disease) may be one reason for this.
There were no survival differences in patients with groups A, O, and AB blood (P = . 47). Percentage of ABO groups stratified by decade of death.
