What is the rarest blood type in the world?
AB negative
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.
What blood group is unique to humans?
AB+ or AB Positive is one of the most unique blood types in the world. AB blood types feature both A and B antigens at the surface of their red blood cells, while most other blood types will only feature one or the other.
Which blood type is most common?
There are four main blood types: type A, type B, type AB and type O. Additionally, if a substance called Rh factor appears on the surface of the red blood cells, a person is considered to be Rh+ (positive). Type O+ is the most common blood type, while AB- is the least common.
What are facts about blood types?
Blood Types. Human blood is grouped into four types: A, B, AB, and O. Each letter refers to a kind of antigen, or protein, on the surface of red blood cells. For example, the surface of red blood cells in Type A blood has antigens known as A-antigens. Each blood type is also grouped by its Rhesus factor, or Rh factor.
What are the percentages of blood?
The blood that runs through the veins, arteries, and capillaries is known as whole blood, a mixture of about 55 percent plasma and 45 percent blood cells. About 7 to 8 percent of your total body weight is blood.
