how the type of blood group is determined

By
If not then you are in the right place. Our blood group is determined based on special kinds of proteins that are present on the surface of red blood cells and in our plasma known as the antigens and the antibodies.

If there is A-antigen present on the surface of RBC along with anti-B antibodies in the plasma then the blood type is “A”.

If there is B-antigen present on the surface of RBC and anti-A antibodies in the plasma then the blood type is “B”.

If there are both the A-antigen and B-antigen present on the surface of RBC and without any antibodies then the blood type is “AB”.

And if there is no A OR B antigen present on the surface of RBC then the blood type is “O”.

And to determine if the blood type is positive or negative, “RH(rhesus) FACTOR” is used. The RH factor is nothing but again a special kind of protein that is present on the surface of RBC.

If this protein is present on the surface of RBC, then the blood group is RHD positive or simply positive else negative.

And on the above basics, our blood group is determined.

There is also a special kind of blood group that exists known as “RH null” or “Golden blood” matches with every type of blood group.

There is a small story behind this. The great lord buddha who started the very oldest and very famous religion, "BUDDHISM '', was once meditating under a tree.
