Less sensitive than PEG for detection of warm reactive autoantibodies. Many laboratories of developing countries perform the tube test only in case the result of the slide test is doubtful. Principle Of Blood Grouping. When the antigen A is present on the red blood cells, then the person is said to have Type A Blood. A person having antigen B on the red blood cells is considered to have Type B Blood. When both antigens, A and B are present on the red blood cells, then the person’s blood type is classified as AB. DiaClon ABO/D + Reverse Grouping. Group B (b) Antigen A 3. Almost half of the population (48%) has blood group O. The test combines the principles of agglutination and gel filtration. • Two principle subgroups of A are: A 1and A 2 • Both react strongly with reagent anti-A • To distinguish A 1from A 2red cells, the lectin Dolichos biflorus is used (anti-A 1 ) • 80% of group A or AB individuals are A 1 and A 1 B • 20% are A 2and A 2 B A 2phenotype • Clinical significance of A 2phenotype o 8% of A 2and 25% of A 2 dextra acrylamide )column with pores that will allow passge of free RBCs but not small enough to trap agglutinated RBCs. Gel Principle/Method. The glass card method seems to be comparable to the gel card method in RBC antibody screening, although in stored samples, antibodies were more frequently detected with the gel card system. Gel column agglutination, which has gained popularity in recent years, also has the unique advantage of detecting mixed-field agglutination patterns, because the high-density media allows a clear separation between agglutinated and non-agglutinated cells, thus indicating the presence of a dual population of red blood cells.
