Abstract
Disclosed is a test instrument for measuring an analyte in a liquid sample by a noble metal colloid aggregation measurement method. The test instrument involves a reaction chamber in which at least the liquid sample is to be reacted with a reagent, wherein the reagent is adhered on at least a part of a surface constituting the reaction chamber in a dried state, and the reagent enables the measurement of the analyte by a noble metal colloid aggregation measurement method. The test instrument additionally involves a supply section for supplying the liquid sample and a flow path for delivering the liquid sample that has been supplied to the supply section to the reaction chamber, wherein the liquid sample that has been supplied to the supply section is delivered to the reaction chamber through the flow path to cause the liquid sample to be brought into contact with the reagent that has been adhered in a dried state, thereby producing a difference in pressure between the supply section and the reaction chamber for the purpose of dispersing the reagent in the liquid sample. When the test instrument is used, the measurement based on an absorbance at a visible region can be achieved, the …
