Group B can donate red blood cells to B's and AB's. Group A can donate red blood cells to A's and AB's. Group O can donate red blood cells to anybody. It's the universal donor.
Type O-positive blood can be transfused to any positive blood type: A-positive, B-positive, AB-positive, and of course other O-positives. Patients with O-positive blood can receive blood transfusions from other O-positives or O-negative donors. The ideal donation types for O+ donors are whole blood or Power Red.
People with O negative blood often wonder how rare their blood is since it is always in demand by hospitals and blood centers. If you have 0 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.
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).
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%
Brothers and sisters don't always share the same blood type. The genotype of both parents plays a role in defining the blood type. For instance, children of parents with the genotypes AO and BO may have the blood types A, B, AB, or O. Thus, siblings do not necessarily have the same blood type.
Famous people with blood type O include Queen Elizabeth II, Paul Newman, Elvis Presley, Ronald Regan, John Gotti, and Gerald Ford.
Rh incompatibility occurs when the mother's blood type is Rh negative and her fetus' blood type is Rh positive.
Type O is routinely in short supply and in high demand by hospitals – both because it is the most common blood type and because type O negative blood is the universal blood type needed for emergency transfusions and for immune deficient infants.
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.
O negative is the most common blood type used for transfusions when the blood type is unknown. This is why it is used most often in cases of trauma, emergency, surgery and any situation where blood type is unknown. O negative is the universal blood type. O negative blood type can only receive O negative blood.
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.
Type O negative red blood cells are considered the safest to give to anyone in a life-threatening emergency or when there's a limited supply of the exact matching blood type. That's because type O negative blood cells don't have antibodies to A, B or Rh antigens.
American actress and model Brooke Shields' royal blood goes without saying, as she has always exhibited queenly confidence. She's the second-most royal celebrity in America, trailing only Hilary Duff. Through Henry II of France, Shields is Queen Elizabeth's 18th cousin once removed.
Royal Roots Research
Surprisingly, royal roots aren't as rare as you might think. More than 60 percent of Americans are descended from royalty, according to Gary Boyd Roberts, author of The Royal Descents of 500 Immigrants.
Rh-null or golden blood
Because Rh-null lacks all possible antigens, it can be donated to people who have blood types that are very different from the main eight. However, Rh-null can only accept blood from people with Rh-null blood type.
A baby may have the blood type and Rh factor of either parent, or a combination of both parents. Rh factors follow a common pattern of genetic inheritance. The Rh-positive gene is dominant (stronger) and even when paired with an Rh-negative gene, the positive gene takes over.
Two O parents will get an O child nearly all of the time.
Monozygotic (identical) twins will have the same blood type, with a few very rare exceptions. Dizygotic (fraternal) twins may have the same blood type, or they may have different types. Therefore, it may be concluded that twins with differing blood types are dizygotic, or fraternal.
Results: The Aboriginal and non-Aboriginal populations had significantly different ABO and RhD distributions (P < 0.001). For Aboriginal individuals, 955/1686 (56.6%) were group O and 669/1686 (39.7%) were group A. In non-Aboriginal individuals, 1201/2657 (45.2%) were group O and 986/2657 (37.1%) were group A.
Blood type O-negative
O-negative blood type is most common in the U.S. among Caucasian adults, at around eight percent of the Caucasian population, while only around one percent of the Asian population has O-negative blood type.
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.
