Abstract
It is an object of the present invention to provide a method or an immunochromatographic test piece, which controls a speed or a direction of development of a specimen on the immunochromatographic test piece, so that a treatment with an acid reagent, nitrite, and a neutralizing reagent is properly controlled. The present invention provides an immunochromatographic test piece for extracting and measuring a sugar chain antigen in a specimen, the immunochromatographic test piece having a neutralizing region impregnated with a neutralizing reagent upstream of a label region, and further having a solid acid reagent or nitrite region impregnated with a solid acid reagent, or with nitrite, upstream of the neutralizing region, wherein a resin-made sheet is sandwiched between the solid acid reagent or nitrite region the neutralizing region so as to suppress the movement of a reagent or the movement of a specimen solution between the regions.
