Group B can donate red blood cells to B's and AB's. Group A can donate red blood cells to A's and AB's. Group O can donate red blood cells to anybody. It's the universal donor.
Type O-positive blood can be transfused to any positive blood type: A-positive, B-positive, AB-positive, and of course other O-positives. Patients with O-positive blood can receive blood transfusions from other O-positives or O-negative donors. The ideal donation types for O+ donors are whole blood or Power Red.
For emergency transfusions, blood group type O negative blood is the variety of blood that has the lowest risk of causing serious reactions for most people who receive it. Because of this, it's sometimes called the universal blood donor type.
O positive blood can't be used universally because it has the Rh factor, but it is compatible with all positive blood types including O+, A+, B+, and AB+. Since over 80% of the population has a positive blood type, type O positive blood is in high demand.
Is A negative blood rare? Around 8% of donors have A negative blood. In comparison, 30% of donors have A positive blood.
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. You can, however, include rainbow trout, salmon, red snapper, cod, sardines, and whitefish to your diet.
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.
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 rarest blood type is Rhnull. Unlike other blood types, people with Rhnull blood have no Rh antigens on their red blood cells. However, of the eight main blood types, AB- is the least common. Researchers estimate that just 1 in 6 million people have Rhnull blood.
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.
Rh incompatibility occurs when the mother's blood type is Rh negative and her fetus' blood type is Rh positive.
A person who is blood type O has to be genetically OO (receiving a gene that codes for neither A nor B from one parent and a gene that codes for neither A or B from another parent). The possible blood types of the parents include OO, AO, and BO.
Type O blood: A high-protein diet heavy on lean meat, poultry, fish, and vegetables, and light on grains, beans, and dairy. D'Adamo also recommends various supplements to help with tummy troubles and other issues he says people with type O tend to have.
A baby may have the blood type and Rh factor of either parent, or a combination of both parents. Rh factors follow a common pattern of genetic inheritance. The Rh-positive gene is dominant (stronger) and even when paired with an Rh-negative gene, the positive gene takes over.
A positive: 30% A negative: 8% B positive: 8% B negative: 2%
The most common blood type in Australia is O positive and the least common is AB negative.
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.
Usually, you'll have the same blood type all of your life. In rare cases, however, blood types can change. The change usually relates to unique circumstances, such as having a bone marrow transplant or getting certain types of leukemia or infections. Not all of these changes in blood type are permanent.
Vegetables are vital to the Type A Diet, providing minerals, enzymes and antioxidants. Type A are very sensitive to the lectins in potatoes, sweet potatoes, yams, cabbage, tomatoes and peppers. They aggravate the delicate stomach of Type A.
Coffee is slightly acidic (pH 5.0–5.1)—type A's need to increase stomach acid since they tend to have very low levels—and can have a stimulating effect because of its caffeine content. Drinking one to three cups per day has some health benefits.
Using data from NYP/CUIMC, we found moderately increased infection prevalence among non-O blood types and among Rh-positive individuals. Intubation risk was increased among AB and B types, and decreased among A and Rh-negative types.
