Question

write the name of two material required for identification of blood groups

Answer 1

For the identification of blood groups we first need to identify the type of antigens in them.

For example 1) in blood group A: there is antigen B

                     2) in blood group B: there is antigen A

                     3) in blood group O: there are no antigens

                     4) in blood group AB: there are present both the antigens A        and B

Also there is the influence of a pigment RH which determines whether a blood group is A,B,AB and O positive or negative..

I hope you have understood it.
