An Rh null person has to rely on the cooperation of a small network of regular Rh null donors around the world if they need the blood. Across the globe, there are only nine active donors for this blood group. This makes it the world's most precious blood type, hence the name "golden" blood.
O negative blood is valuable because it can be transfused to anyone, regardless of their blood type.
The rarest blood type is Rhnull. Unlike other blood types, people with Rhnull blood have no Rh antigens on their red blood cells. However, of the eight main blood types, AB- is the least common. Researchers estimate that just 1 in 6 million people have Rhnull blood.
The rarest blood type in existence is Rhnull blood. This stuff is characterized by a complete lack of antigens in the Rh system, which is the largest blood group system. This includes the D antigen (Rh factor, baby), plus the other 50-something antigens in the group.
The most common blood type in Australia is O positive and the least common is AB negative.
Of the eight main blood types, people with Type O have the lowest risk for heart attacks and blood clots in the legs and lungs. This may be because people with other blood types have higher levels of certain clotting factors, which are proteins that cause blood to coagulate (solidify).
O-negative is the universal blood type, meaning that anyone can receive your blood. And O- and O+ blood are both extra special when it comes to traumas where there is no time for blood typing.
In molecular history, type A appears to be the 'oldest' blood type, in the sense that the mutations that gave rise to types O and B appear to stem from it. Geneticists call this the wild-type or ancestral allele.
Blood groups in Australia
According to Australian Red Cross Lifeblood, the percentage of blood group frequency in Australia is: O positive - 40% O negative - 9% A positive - 31%
Only 7% of the population are O negative. However, the need for O negative blood is the highest because it is used most often during emergencies. The need for O+ is high because it is the most frequently occurring blood type (37% of the population). The universal red cell donor has Type O negative blood.
As if his regular service weren't enough, Fischer learned his O-positive blood is Code 96. That means it lacks a particular combination of antigens, which makes it especially useful for specialized cases: transplants, people who have been transfused so often that they reject regular blood, and fragile babies.
Famous people with blood type O include Queen Elizabeth II, Paul Newman, Elvis Presley, Ronald Regan, John Gotti, and Gerald Ford.
Usually, you'll have the same blood type all of your life. In rare cases, however, blood types can change. The change usually relates to unique circumstances, such as having a bone marrow transplant or getting certain types of leukemia or infections. Not all of these changes in blood type are permanent.
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.
Indeed, the authors retrospectively reviewed blood group distribution in a cohort of patients stratified by decade of death and found that patients with group B blood had an overall decreased survival (p<0.01) compared with patients with the other blood groups.
(7,8) Their high rate of blood group O suggests that the Amerindians and Eskimos are directly descended from Cro-Magnon ancestors, probably Mongolians, who migrated around 15,000 B.C. to the Americas.
The main findings of our study are that (1) O type subjects have thicker FCT and less TCFA compared to non-O type subjects and (2) O type subjects have larger minimum lumen area and minimum lumen diameter compared to non-O type subjects.
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. However, some blood types are both rare and in demand.
This means that because everyone has more Rh proteins than an Rh-null person, everyone can safely and confidently receive this blood in a transfusion. This is why “golden blood” is lifesaving: in emergencies when blood transfusion is needed but the patient's rare blood type is not known, it can be given.
Research suggests that people with certain blood types — namely A and B — are at higher risk to develop blood clots and to have heart attacks and strokes. Join our fight to lower prescription drug prices. Help us continue to fight for affordable drug prices for all older Americans.
In an emergency situation where a patient's blood type is unknown, type O negative blood is the only blood type that is safe to use. The reason is that it is compatible with all blood types. Type O negative is known as the universal blood type.
AB Blood Type – Foods to Avoid
If you have AB blood type, you should avoid heavy meats such as beef, pork, and even chicken. All shellfish and seafood items like octopus, eel, and yellowtail are no good.
