There are four major blood groups determined by the presence or absence of two antigens – A and B – on the surface of red blood cells. When it comes to plasma, O blood, both positive and negative, is not so universal and they can only give plasma to other O types. The following map shows the distribution of the O, A, B, and AB blood types in the population by country in Europe (with colouring indicating the most common type, which in itself is not a reliable indicator of anything else; the actual figures are more important). Those with A+ blood can receive blood from Rh negative and positive A and O types. If both of your parents have blood type “A”, then your blood type will either be type “A” or “O”. AB- has both A and B antigens on its red cells which is why its compatible with all the other main Rh negative blood types. Since AB blood, both Rh positive and negative, contains no A or B antibodies it is the universal plasma donor and anyone from any blood group can receive plasma from AB blood. Unlike B+ blood, B- blood can be given to both types of B and AB blood. Factors that determine your blood type and how you can find out your blood type. O-positive: 38 percent 2. According to various sources, only about 1 in 50 or so blood donors is B-, so B- donors are always in high demand to ensure that the supply is stable. While demand for AB+ blood is low, AB plasma, both Rh negative and positive, is always wanted because AB blood is the universal plasma donor. It is more convenient and easy to seek for donors or process application for the blood type in blood banks. Influenced by their heads rather than their hearts, they have great self-control and are rational. You should be lucky if yours is the most common blood type, which is the type “O”. The B blood type is according to his research the blood type of nomads. However, this is just a very basic labeling of our blood types and each type has further subdivisions. However, O blood types can be given plasma from anyone. Of the A blood types, A- is much rarer than A+, which is actually pretty common. Alvin Goodley | October 21, 2019October 18, 2019 | People. O- blood is used often in transfusions when the recipient’s blood type is unknown, like during trauma or emergency situations. Unfortunately, there is such a low number of people with Rh-null blood that it is used sparingly and they are encouraged to donate regularly so that the blood will be there for themselves should they need a blood transfusion. Globally, the most common blood type is O, but the most common blood type of Europeans is A. B-negative: 2 percent 7. While there are only eight main/common blood types, there are an additional 61 possible antigens in the Rh system, which means that the eight main blood types can be subdivided into millions of different blood types. B- is also fairly rare among the world’s population, comprising only about 1.11% of the total population’s known blood types. However, Rh-null can only accept blood from others with Rh-null. While people with A- blood can’t donate blood and plasma to just anyone, A- blood is valuable because it is the universal platelet donor and A- platelets can be given to anyone of any blood type. Similar to B- blood, A- blood can be donated to anyone with A or AB regardless of the positive or negative. Just 2% of donors are B negative, making one of the rarest blood types. Rare blood types. Since B- blood lacks the A antibody in the red cells, it can only receive blood from B- and O- (the universal donor). ... A positive is the second most common blood type. According to the American Red Cross, there … Type of identity – “Nomad”. The most common blood types are A+, A–, B+, B–, O+, O–, AB+, and AB–. Patients with B+ blood can only receive blood from B and O, both negative and positive types. CMV is a flu-like virus that most adults have been exposed to at some time in their life and while CMV antibodies, which remain in the blood forever like all viruses, are safe for adults, they can be fatal to babies. Rh-null occurs when a person’s blood lacks all of the 61 possible antigens. While AB- can receive blood from all other Rh negative types, it can only donate to others with AB blood, both Rh negative and positive. Additionally, Rh positive blood types are much more common than Rh negative blood types, which is another reason why O+ blood is always needed and important. O+ blood is the most common blood type in the world and while it is not quite as universal as O- blood (O+ can be given to all Rh positive types but not the Rh negative types), it is still the most used blood, according to the American Red Cross. Origin and type of identity. A+ blood is the second most common blood type just behind O+. In addition to the A and B antigens, there is a protein called the Rh factor, which can be either present (+) or absent (–), creating the 8 most common blood types (A+, A-, B+, B-, O+, O-, AB+, AB-). While O+ blood can be given to anyone with Rh positive blood types, individuals can only receive blood from O+ and O- donors. How does blood typing work? On the opposite end of the O- blood’s universal donor status is AB+, which is the universal recipient. Although O- blood is already very special, O- donors who are CMV (Cytomegalovirus) negative are extra special because their blood is safe to give to babies. In the United States, the average distribution of blood types is as follows: 1. Rh-null blood was first discovered in 1961 in an Australian Aboriginal woman. On the other hand, those with A- blood can only get blood from A- and the universal donor O-. 12 Rarest League of Legend Skins Ever Released, used to treat individuals with sickle cell sickle cell disease, O- donors who are CMV (Cytomegalovirus) negative. This is because type O negative is the universal donor and type O positive is the most … In the United States , type O positive is the most common blood type. You’ll find below a few factors on how a particular blood type is formed which has made “O” the most common blood type. Less than 2% of the world’s population has A- blood. More about A positive. The least common blood types are type B negative and type AB negative. While it is common, A+ blood can only be given to others with A+ or AB+ blood. The rarest of these is type AB–. AB-positive: 3 percent 8. Unfortunately, O- blood is pretty uncommon and because of how important the blood is, donors are in very high demand around the world. In general, there are four main blood types or blood groups – A, B, AB, and O – with both Rh negative and Rh positive variants for each group. According to the American Red Cross, the platelets from A+ blood are in high demand for patients undergoing chemotherapy treatments. The scarcity of Rh-null blood coupled with its unique properties make it very valuable to scientific research, hence its “Golden Blood” reputation. B-positive: 9 percent 6. 1. According to the American Red Cross, O- blood is the always the first to run out during a blood shortage due to its universality. According to the UK’s National Health Service (NHS), fresh frozen plasma can only be produced from male donors because plasma from female donors can develop harmful antibodies.
