"Because Rhnull blood can be considered 'universal' blood for anyone with rare blood types within the Rh system, its life-saving capability is enormous.
O negative blood can be used in transfusions for any blood type. 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.
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.
Rh-null blood can be accepted by anyone with a rare blood type in the Rh system. “Golden blood” is as rare in reality as it was in ancient Greek mythology: only forty-three people in the world are known to have had this blood type.
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).
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.
O negative blood is valuable because it can be transfused to anyone, regardless of their blood type.
The new group is called the Er blood group, CNN reported. According to the journal "Blood," there are a total of five E-R antigens in this group based on genetic variations. The blood type can cause immune cells to attack mismatched cells, which has happened in other cases where blood types are incompatible.
Donors with blood type O... can donate to recipients with blood types A, B, AB and O (O is the universal donor: donors with O blood are compatible with any other blood type)
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.
Heterogeneity between countries has become apparent and has led to the conclusion that the European Roma are composed of two different populations, characterised respectively by a high and a low frequency of blood group B [23], or defined as East and West European Roma, with the former closely related to Indian ...
Famous people with blood type O include Queen Elizabeth II, Paul Newman, Elvis Presley, Ronald Regan, John Gotti, and Gerald Ford.
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.
Blood type generally does not change during lifespan. However, in some cases, blood type can change because of some disorders like autoimmune diseases and cancers.
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%
O negative is the universal blood type. O negative blood type can only receive O negative blood. O negative donors who are CMV negative are known as Heroes for Babies at the Red Cross because it is the safest blood for transfusions for immune deficient newborns.

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.
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.
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. The A and B mutations appeared in the last 20,000 years and haven't spread through the population yet.
Rh incompatibility occurs when the mother's blood type is Rh negative and her fetus' blood type is Rh positive.
Peptic ulcer also has a connection with the ABO blood group, and it was the first to be identified. Blood type O individuals showed that they had higher susceptibility to peptic ulcers [1, 9]. Gastritis and ulceration of the stomach/duodenum were later correlated with infection with the bacterium Helicobacter pylori.
Various studies have reported conflicting results on the distribution of blood groups among acute leukaemias . Some of the studies discovered significant difference and higher percentage of O blood type among patients with acute leukemia(13).
