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.
While Shimizu and Colleagues10 found that blood type B was associated with longevity, Mengoli and Colleagues6 and Brecher and Hay12 concluded that group B was inversely correlated with age. In addition, there are isolated reports of group A7 and group O9 being associated with longevity.
The survival curve in group B was worse than that in groups A, O, and AB. These findings suggest that in our patient population, blood group B is not a marker for longevity but may be a marker for earlier death.
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 general, non-O blood types are more susceptible to diseases than O.
Blood type and stress
Type A may exhibit more anxious behaviour than other types. The blood types B and AB have been found to respond better to stress. And blood type O was found to have the lowest amounts of cortisol in their bodies.
Recent data suggests that people with blood type A have a significantly higher risk of acquiring COVID-19 than non-A blood types. Blood type O seems to have the lowest risk. Yet these risks are relative, meaning people with type O blood are not immune to COVID-19.
In an emergency situation where a patient's blood type is unknown, type O negative blood is the only blood type that is safe to use. The reason is that it is compatible with all blood types. Type O negative is known as the universal blood type.
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.
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.
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).
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.
Among them, the cell with the shortest lifespan is the: Platelets: Platelets are small, disc-shaped cells that play an essential role in blood clotting. They are produced in the bone marrow and circulate in the blood for about 7-10 days before being removed from the body.
People with type A, type B or type AB blood are more likely than people with type O to have a heart attack or experience heart failure, according to the American Heart Association.
The bottom line on blood type and Covid risk
People with Type O blood might be slightly more protected from the virus, and people with Type A slightly more vulnerable. The discovery of Type O's protective effect is crucial to building an understanding of how the virus works.
O negative donors are often called 'universal donors' because anyone can receive the red blood cells from their donations.
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.
What's the rarest blood type? 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.
The risk of ADHD is increased in the presence of alleles O and A, but the risk is reduced in the presence of allele B.
The ABO gene is connected with brain function and memory loss. People who have blood types A, B, and AB are up to 82 percent more likely to develop cognition and memory problems — which can lead to dementia — compared to those with Type O.
Type I bipolar patients in Budapest were reported to have type O blood more often and types A and B blood less often than Type II bipolar patients.
The most common blood type in Australia is O positive and the least common is AB negative.
