Which is the rarest blood group?
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.
Which is the best blood group?
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. The universal plasma donor has Type AB blood.
What are the 29 blood groups?
Blood group names
- A+ (A positive) if you have A and rhesus antigens.
- A− (A negative) if you have A antigens but don’t have rhesus antigens.
- B+ (B positive) if you have B and rhesus antigens.
- B− (B negative) if you have B antigens but don’t have rhesus antigens.
- AB+ (AB positive) if you have A, B and rhesus antigens.
What is the best blood group?
So O-Neg and AB are the best blood groups! Answer: There are four recognised groups – O, A, B and AB – which refer to the marker (antigens) carried on the surface of the blood group – A carries the A antigens etc. B the B antigens and other cells recognise A antigens as the enemy, so carry anti-A.
What are all the names of all the blood types?
There are basically four main blood groups or types and they are A, B, AB, and O. They are further divided into what is known as the Rh system which expands the blood types to eight categories and they are A(+), A(-), B(+), B(-), O(+), O(-), AB(+), and AB(-).
What are the eight blood types?
People are probably most familiar with these types because they include the eight common blood types: A-positive, A-negative, B-positive, B-negative, AB-positive, AB-negative, O-positive, and O-negative.

What are all the possible blood types?
Each person’s blood cells contain different combinations of antigens which determine the person’s blood type. The possible blood types are A, B, AB, and O, and any of these could also be positive or negative for Rh factor (another antigen).
