Abstract
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.
