Abstract
A method for assigning an antibody standard and determining a minimum detection limit of an antibody detection reagent specifically includes the following steps: S1, determination of a neutralized antigen equivalent of an antibody standard or a sample: an antigen with a known purity and concentration is subjected to a gradient dilution using a matrix, an equal amount of an antibody standard or antibody-containing sample is added to each of the gradient diluents with different concentrations respectively, and after a reaction, each mixture is subjected to an antibody detection using a first antibody detection reagent, to determine the neutralized antigen equivalent of the antibody standard or sample; S2, determination of an antibody titer of the sample; and S3, acquisition of the minimum detection limit of an antibody detection reagent.
