Is A negative blood rare? Around 8% of donors have A negative blood. In comparison, 30% of donors have A positive blood.
Although Rh positive is the most common blood type, having a Rh-negative typing does not indicate illness and usually doesn't affect your health.
Or to put it another way, about 1 in 15 people have O negative blood. Is that rare? Only about 1 in 67 have B negative blood, making it rarer. However, the rarest blood type in the world is Rh-null, which is so rare most of us have never heard of it.
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.
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.
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.
Yes, the blood group AB is rare and least prevalent in India. As per records, only 7% of people in India have the blood type AB.
Only 1 in 16 people have A negative blood. If you have A negative blood you can donate to anyone with a blood type of A or AB regardless of the positive or negative, however if you have A negative blood you can only receive A- or O- blood.
Having a negative blood group does not have consequences as such but being a rare group makes it difficult to get the blood group at the time of injury. Another disadvantage is that if the mother is Rh negative whereas the son is Rh positive, it leads to high risk of getting infected with erythroblastosis fetalis.
Background: Weak blood group A and B phenotypes are correlated with ABO glycosyltransferases exhibiting single-amino-acid changes and/or C-terminal modifications.
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.

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).
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.
O− blood, also called "universal donor," is perhaps the most valuable blood in the world because it can be transfused to nearly any blood type (except when the person has some rare antigen outside of the main ones).
The new blood group is called Er or erantigens. There are five blood types in this group based on genetic variations of what's known as the Piezo1 protein, which is found on the surfaces of red blood cells.
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.
Rh incompatibility occurs when the mother's blood type is Rh negative and her fetus' blood type is Rh positive. Antibodies from an Rh negative mother may enter the blood stream of her unborn Rh positive infant, damaging the red blood cells (RBCs).
A type's ancestors were mainly farmers, so it is believed that you should avoid all pork, beef, lamb, and game meats. You should eat lean cuts of turkey and chicken only occasionally.
Blood group O is the most common blood group. Almost half of the UK population (48%) has blood group O. Receiving blood from the wrong ABO group can be life-threatening. For example, if someone with group B blood is given group A blood, their anti-A antibodies will attack the group A cells.
O-positive (O+) is the most common blood type by average percentage.
The patient who is both aggressive and perfectionistic can be surmised to be of type O blood but to have elevated norepinephrine and moderate dopamine.
Blood type O negative (O-) is the universal donor. This means that a person with any other blood type can safely receive your blood. It doesn't contain any antigen markers that other blood types recognize as not belonging. Providers use type O negative blood the most in emergencies when someone needs blood fast.
Blood type A is the oldest, and existed even before the human race evolved from our ancestors.
