The present invention provides a method for reducing reagent usage, comprising the steps of providing a retainer, at least one group of loopholes being provided on the sidewalls of said retainer; providing a colorimetric glass, adapted to be inserted into said retainer, for receiving the first reagent to be observed through said loopholes; providing a cap, for capping the colorimetric glass and the retainer into a whole, after the colorimetric glass being inserted into the retainer. The present invention mainly uses a reagent tube with a retainer having a new structure, a colorimetric glass and a cap, storing the first reagent only in the colorimetric glass, and the volume of the colorimetric glass is far less than that of the current reagent tube, thus the usage of the reagents can be reduced effectively. After comparison with experiments, in the method, the usage of the first reagent or second reagent is reduced separately by in amount of 70% to 90% or by in amount of 60% to 75%, and thus reducing the detecting cost effectively and economic burden to the detector.
