An immunochromatographic test piece is provided containing a control line detection reagent that is not affected by the concentration of an analyte to be detected. The immunochromatographic test piece is for quantifying an analyte in a biological sample, and includes (a) a conjugation pad impregnated with a detection reagent that specifically binds to the analyte, and a control line detection reagent; and (b) a porous membrane pad on which an antibody for capturing the analyte is immobilized upstream, and an antibody for capturing specifically the control line detection reagent is immobilized downstream.

Immunochromatographic test piece

Provided are a measurement sample diluent that enables the measurement of the proportion of HbA1c in the total Hb molecules in a measurement sample (HbA1c (%)), with high sensitivity, high accuracy, and high correlation with HPLC without being affected by the length of time required to mix a measurement sample with the measurement sample diluent and to drop the mixture onto an immunochromatographic specimen for measuring HbA1c; and a kit containing the measurement sample diluent. The present invention relates to a measurement sample diluent for immunochromatography for quantifying the proportion of hemoglobin A1c in the total hemoglobin molecules in a measurement sample (hemoglobin A1c (%)); and the measurement sample diluent is an aqueous solution that contains a non-ionic surfactant, an anionic surfactant, and a buffer.
