The ranking of ABO blood groups phenotypic distribution in China is O > A > B > AB. The proportions of A, B, O and AB type in China population are 28.72%, 28.17%, 34.20%, and 8.91%, respectively.
In China, women often don't learn that they have a rare blood type until they become pregnant or plan to become pregnant. This was precisely the case for Wang, who discovered three years ago during a routine prepregnancy checkup that she has Rh negative blood — nicknamed “panda blood” because of its rarity.
RH negative blood, compared with the common A, B and O types, is a variety highly unusual in China. With only 0.1% to 0.3% of the population having this blood running through their veins, it is therefore referred to as "panda blood." Rare as the blood type is, people with RH negative blood must not be ignored.
Approximately 45 percent of Caucasians are type O (positive or negative), but 51 percent of African-Americans and 57 percent of Hispanics are type O. Minority and diverse populations, therefore, play a critical role in meeting the constant need for blood. Types O negative and O positive are in high demand.
The most common blood type in Australia is O positive and the least common is AB negative. The table below lists each of the blood types, including how common they are across the Australian population. This is the most common blood type. O- can be safely given to any patient, regardless of their blood type.
Whilst only 6.5% of the Australian population are group O RhD negative, group O RhD negative red blood cells have represented up to 17% of issues to Australian health providers.
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.
Asian: 0.1% AB-negative, 0.4% B-negative, and 0.5% A-negative. Caucasian: 1% AB-negative, 2% B-negative, and 3% AB-positive.
Australia also saw an increase in the rates of people with B and AB positive blood, a reflection of migration from countries such as China and India, where those types are more prevalent. Overall, our blood is becoming more positive — that's Rhesus D or RhD positive.
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.
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).
In Japan, AB is the rarest blood type, while Type A is the most common one, followed by type O.
Blood type A is the oldest, and existed even before the human race evolved from our ancestors.
Asia. Even though O+ remains the most common blood type here, blood type B is relatively common too. Nearly 20% of China's population has this blood type, and it is also fairly common in India and other Central Asian countries.
O negative blood is valuable because it can be transfused to anyone, regardless of their blood type. Hospitals need to have it on hand for emergencies. In addition, emergency services, including ambulances and helicopters, may also carry it to keep patients alive while they're being transported to a hospital.
Type O positive blood is given to patients more than any other blood type, which is why it's considered the most needed blood type.
Each person has two Rh factors in their genetics, one from each parent. The only way for someone to have a negative blood type is for both parents to have at least one negative factor. 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.
In Australia, about 83% of people have the D antigen on their red cells, so their blood type is called RhD positive. The other 17% don't have the D on their red cells and are called Rh negative. The percentage of Rh negative people varies in different countries.
Basques were found to have the highest incidence of Rh negative blood of any people in the world, significantly higher than the rest of Europe, even significantly higher than neighboring regions of France and Spain.
Rh-negative frequencies of about 29% were documented among Basques and in distinct populations living in the High Atlas Range of Morocco [25], which have the highest reported prevalence of Rh-negative phenotypes apart from that from Saudi Arabia above.
Based on the primary races hypothesis, it was thought that in the three major races of man, blood groups A in Europe, B in Asian, and finally O in South America have been emerged and gradually due to the migration and mixing of the races, became the present situation.
The gene for type O is 'recessive', because if you have one gene for O and one for A, then you still end up with A antigens on your cell membranes, and the same goes for O and B. In order to be group O, you need both parent cells to be O. But group O is still more common simply because it is the ancestral form.
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.
