Sensitivity of local antigen: Serial tenfold dilutions (Undiluted, 10-1 to 10-6) of all the three antigens were prepared in Normal saline and each dilution was subjected to agglutination test with known positive and negative antisera to find out the minimum number of bacterial cells (best dilution) required to be used for visible agglutination.
The cell washing process can also help to remove protein agglutination and some aged RBC segments to avoid test interference, as well as eliminate lactic acid that accumulates on the RBCs for better preservation.
