Abstract
An object of the present invention is to provide a method of measuring the amount of a compound containing a sugar chain in a biological sample by a sandwich immunoassay method using a labeled lectin, which method is suitable for reduction of noise originating from impurities and determination of the exact amount of a target compound. The present invention provides a method of measuring the amount of a target compound containing a sugar chain in a biological sample by a sandwich immunoassay method using a labeled lectin (including cases where a target compound-capturing substance other than an antibody is used as a ligand), the method containing adding a sugar chain compound which competes (crosses) with impurities contained in the biological sample in binding with the labeled lectin.
