Multiassay method for determining the concentrations of antigens and interferants

Multiassay method for determining the concentrations of antigens and interferants

Official Gazette of the United States Patent & Trademark Office Patents 1239(1), Oct 3

A method of determining the concentration of a sample antigen in the presence of an interferant by (1) running two immunoassays on the sample: one assay where the interferant influences the binding of both the sample antigen and a labeled antigen and a second assay where the interferant influences the binding of the sample antigen but not the labeled antigen; (2) obtaining a plot of the possible sample antigen concentrations versus the possible interferant concentrations corresponding to the readout for the sample for each of the two immunoassays; and (3) determining the sample antigen concentration and the interferant concentration which correspond to the point that appears in both the immunoassays plots.
