Broken down by race, type O-’s prevalence is 37% among Caucasians, 47% among African Americans, 39% among Asians, and 53% among Latino-Americans, according to the American Red Cross. In the United States, type O- is the most common blood type. Meanwhile O-, the universal cell donor, can only donate plasma to O- patients. So AB+, which can only donate cells to AB+ patients, becomes a universal plasma donor. Also note that blood group compatibilities are reversed for plasma transfusions. The least common blood types are B- and AB. It is called the universal donor type because it is compatible with any blood type. Type O blood is constantly in high demand in hospitals because O- is the universal donor and O+ is the most common blood type. Type O-negative blood does not have any antigens. AB negative (AB-) - Can donate cells to AB+/-Īs shown above, Type O- blood can be used in transfusions for any blood type.AB positive (AB+) - Can donate cells to AB+.O negative (O-) - Can donate cells to all types (universal donor).O positive (O+) - Can donate cells to A+, B+, AB+, and O+.Your blood group is determined by the genes you inherit from your parents. B negative (B-) - Can donate cells to B+/- and AB+/- There are 4 main blood groups (types of blood) A, B, AB and O.Donors with types AB- and AB+ blood are universal plasma donors, while patients with type AB+ are universal red cell recipients because they can receive red cells from all types. B positive (B+) - Can donate cells to B+ and AB+ Whose type can you match Donors with type O- blood are universal red cell donors whose donations can be given to people of all blood types.A negative (A-) - Can donate cells to A+/- or AB+/.You Can Search AB negative Donors In India By State And Contact With Them. A positive (A+) - Can donate cells to A+ and AB+ Select Your State For Find AB-ve Blood Donors In Emergency.Together, the ABO system and the Rh system give us the eight main blood types: In addition, blood is further classified as either positive (+) or negative (-) depending upon whether it contains a protein known as the Rh factor. When the mothers Rh factor is negative and the babys is positive, it can cause the mothers immune system to make Rh antibodies that attack the babys red. If a patient receives an incompatible blood type, their body will attack it like a life-threatening infection rather than a life-saving transfusion.īlood falls into one of four major blood groups depending upon the presence or absence of two antigens-named A and B-on the surface of its red blood cells (and the opposite antibodies in its plasma). Blood type is particularly important during blood transfusions because some blood types are incompatible with one another. Blood type, also called blood group, is determined by the presence or absence of specific antigens, which can be proteins, carbohydrates, glycoproteins, or glycolipids. The AB blood type has both A and B antigens on its red cells but does not include A or B antibodies in the plasma.Not all blood is the same. ![]() Hispanic and Asian people have less frequency of AB negative blood with 0.2 percent and 0.1 percent, respectively. ![]() Among Caucasians, one percent of people have AB negative blood, while the level among African Americans is 0.3 percent. Variations in the distribution of AB negative blood occurs heavily along racial and ethnic lines, according to the Red Cross. Only one in every 167 people have AB negative blood, or about 0.6 percent of the entire population in the United States, as stated in The Blood Connection. Commonly used to treat victims of shock, burns and clotting disorders, AB negative plasma is needed at donation sites nationwide to ensure a sufficient supply. In this instance, “universal” means that AB negative plasma is safe to give to anyone because of its composition. AB negative blood is particularly important because it is the type of blood required for universal plasma donation, according to The Blood Connection.
