Measurement method of test instruments and analyte using the same for measuring the analyte in the sample

Reagent has a reaction chamber to react with a reagent at least a liquid sample, at least a portion of the surface constituting the reaction chamber; the analyte in the liquid sample to a test device for measuring the precious metal colloid agglutination assays the liquid supplied to and supply unit; but are dry coverage, and reagents, the analyte be measurable reagent precious metal colloid agglutination assays; Furthermore, the supply unit for supplying a liquid sample comprising a channel for carrying a sample to the reaction chamber; a liquid sample supplied to the supply portion, and the dry coverage reagent by transferring the reaction chamber and then through the passageway in contact with the liquid sample liquid sample can generate a pressure differential in the reaction chamber and the supply portion for dispersing in, the use of the test instrument is capable of measuring based on the absorbance in the visible part, can accurately measure the analyte in a short time It is possible to suitably measure the POCT field.
