What is A1B blood group?
A1 and A2 are the major subtypes of blood group A and differ from each other both qualitatively and quantitatively. The cells of approximately 80\% of all group A or AB individuals are A1 or A1B and 20\% remaining are A2 or A2B or weaker subtypes.
What is the blood group of a subtype?
blood type A and subtyping results show that the donor does not have the A1 subtype is referred to as having blood type A, non-A1. other than A1 (i.e. non-A1, negative for A1). A2B is used as shorthand for any blood type AB subtype other than A1B (i.e. non-A1B, negative for A1B).

What is a Group A subtype?
• Subtypes for blood type A include A1, A2, Ax, Aint and others, but the most common is A1. • If the donor is not subtype A1, it means they have less A antigen on their red blood cells (RBCs) and organs, which allows them to donate to recipients outside of their primary blood type.

Yes. Blood type A1B is the predominant subgroup of the overall type AB group. Approximately 80\% of group A and group AB individuals react with anti-A1 reagent and are classified as A1 or A1B. Red cell phenotype is determined by the presence or absence of terminal sugars on the red cell membrane.
How are A1 and A1b red cells classified?
Approximately 80\% of group A and group AB individuals react with anti-A1 reagent and are classified as A1 or A1B. Red cell phenotype is determined by the presence or absence of terminal sugars on the red cell membrane. On red cells with the “A” sugar, subgroups are determined by the number of antigens on the cell surface.
Can A1B donate blood from any other blood group?
Well, to put it in a simple way blood groups are categorised under landsteiner ( A,B,AB,O) and Rhesus (+ve,-ve). So A now has subgroups A1 and A2 and THAT,my friend is where A1B comes form .
