REAGENT REACTION DETERMINATION METHOD AND APPARATUS, STORAGE MEDIUM AND TEST TUBE

A reagent reaction determination method and apparatus, a storage medium and a test tube. The reagent reaction determination method comprises: outputting a brightness control signal to a light-incident component, so as to control the light-incident component to emit RGB light, and adjusting the brightness control signal according to a preset step length, so as to adjust the brightness of the RGB light; detecting a brightness change in light exported by a light-emergent assembly, so as to generate an electrical signal measured value; and when the electrical signal measured value is less than a preset threshold value, performing interpolation calculation on the current brightness control signal, so as to obtain a brightness control signal estimated value, and then performing determination on a reaction result in a reagent reaction cavity according to the brightness control signal estimated value. Therefore, by means of the reagent reaction determination method applied to a test tube in the present embodiment, th
