3 Principle

Water-soluble A, B, and H antigenic substances are present in secreted human fluid plaques, and the antigenic substance is a hapten, which can specifically Binding to the corresponding antibody, thereby inhibiting the agglutination of the antibody and the corresponding indicator red blood cells, and agglutinating according to the antibody and the corresponding indicator red blood cells In the case, the ABO blood type of the human body fluid spot is determined.

4 reagents and equipment

4.1 Reagents a) Standard anti-A antibody, standard anti-B antibody reagent. Meet the requirements of GA 471-2004; b) anti-H antibody reagent (potency should be greater than 16 times); c) 2% to 3% of type A, type B, type O humans indicate red blood cells (see Appendix A); d) saline. 4.2 Equipment a) bench top centrifuge; b) optical microscope; c) concave glass plates, straws, test tubes, centrifuge tubes; d) ophthalmic scissors, ophthalmology; e) the applicator and the applicator tip; f) Marker.

5 Method of operation

5.1 Standardization of antibodies See Appendix B. 5.2 Inspection steps 5.2.1 Cut the body fluid spot to be sampled into a small centrifuge tube, add a small amount of saline solution (to absorb 3 drops is appropriate), and fully Stir and soak, depending on the age of the liquid spot of the sample, soak for ten minutes to several hours. ......
