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.
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.
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%
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).
Patients with types B or AB blood were more likely to test positive for COVID-19, whereas those with type O were less likely to test positive.
O negative donors are often called 'universal donors' because anyone can receive the red blood cells from their donations. Although about 8% of the population has O negative blood, it accounts for around 13% of hospital requests for red blood cells.
Which blood types are in demand? Some blood types are in higher demand from hospitals than others. For example, it's estimated that around 8% of people have O negative blood, but O negative makes up 13% of requests from hospitals. This is because anyone can receive the red cells from O negative donors.
People with type O blood enjoy a slightly lower risk of heart disease and blood clotting, but they may be more susceptible to hemorrhaging or bleeding disorders.
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. Only around seven percent of.
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.
Those with type O blood should choose high-protein foods and eat lots of meat, vegetables, fish, and fruit but limit grains, beans, and legumes. To lose weight, seafood, kelp, red meat, broccoli, spinach, and olive oil are best; wheat, corn, and dairy are to be avoided.
Famous people with blood type O include Queen Elizabeth II, Paul Newman, Elvis Presley, Ronald Regan, John Gotti, and Gerald Ford.
That said, there's one blood type that puts the rarity and universality of O negative to shame. That's Rh-null, also know as “golden blood.”
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.
Why? 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.
O negative blood is missing both the A antigen and the B antigen and does not contain the protein for Rh positive blood. This means that it's missing those things that could cause a bad reaction during a blood transfusion and can be given to any blood type.
A woman's blood group could influence her chances of getting pregnant, scientists have found. Those with blood type O may struggle to conceive due to a lower egg count and poorer egg quality, while those with blood group A seem to be more fertile.
Type O-negative blood can be transfused to ALL blood types. Patients with an O-negative blood type can only receive O-negative blood transfusions.
Blood is further classified as being either "Rh positive" (meaning it has Rh factor) or "Rh negative" (without Rh factor). So, there are eight possible blood types: O negative. This blood type doesn't have A or B markers, and it doesn't have Rh factor.
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.
Ray et al [21] found that subjects with type O and Rh-negative blood were protected from viral infection, severe illness, and mortality.
Stowell, MD, an associate professor of pathology at Harvard Medical School in Boston. “But these findings do not demonstrate that blood group O individuals are protected from the virus.” Depending on the variant of the virus, the risk of infection may be 25 to 50 percent higher in type A cells versus type O cells.
