To provide a novel suppression method of a prozone phenomenon.SOLUTION: There is provided a suppression method of a prozone phenomenon in an immunological test method by immunochromatography, including an antigen-antibody reaction between food allergen contained in a food product and a labelled antibody. In the suppression method of a prozone phenomenon, as the labelled antibody, a labelled antibody labelled with a resin-metal composite body is used, which has a structure formed by immobilizing a plurality of platinum particles on resin particles.SELECTED DRAWING: None 【課題】新規なプロゾーン現象の抑制方法を提供する。【解決手段】食品中に含まれる食物アレルゲンと標識抗体との抗原抗体反応を含む、イムノクロマトグラフィーによる免疫学的検査方法におけるプロゾーン現象の抑制方法であって、前記標識抗体として、樹脂粒子に複数の白金粒子が固定化された構造を有する樹脂−金属複合体で標識した標識抗体を用いることを特徴とする、プロゾーン現象の抑制方法。【選択図】 なし
