Method for pretreatment of specimen for immunochromatographic test

Abstract

An immunochromatographic method for a trace amount of an antigen or an antibody such as SARS-COV-2 including use of saliva, enabling highly sensitive immunochromatographic antigen or antibody detection even when the saliva is used. A method for pretreatment of a specimen for an immunochromatographic test, including passing the saliva through a porous member capable of supporting a viscous component in the saliva to remove the viscous component, passing the liquid that has passed through the porous member through a filter having a hole diameter of from 0.1 μm to 10 μm, and concentrating an antigen or an antibody in the liquid that has passed through the filter.
