Useful For
Useful in determining the blood type of patients.
ABO grouping and Rh typing are based on the principle of agglutination. Normal human red blood cells possessing these antigens will agglutinate in the presence of antibody directed toward those antigens.
Routine testing for determining the ABO group consists of testing the red cells with anti-A and anti-B (forward type) and testing the plasma/serum with A1 and B red cells (reverse type). Both the forward red cell testing and the reverse plasma testing are required for routine ABO tests on patients because each serves as a check on the other.
