A blood test is used to determine whether the A and/or B characteristics are present in a blood sample. It is not possible to determine the exact genotype from a blood test result of either type A or type B. If someone has blood type A, they must have at least one copy of the A allele, but they could have two copies.Their genotype is either AA or AO. Similarly, someone who is blood type B could have a genotype of either BB or BO. blood test is used to determine whether the A and/or B characteristics are present in a blood sample.
