Methods and systems for detecting occult blood and other analytes in the water of a toilet bowl release a dye reagent into the water which produces an observable signal in the presence of the blood or other selected analytes. The dye reagent is preferably dispersed as a liquid, powder, gel, or other form which rapidly mixes and combines with the sample. Additionally, the water of a toilet bowl will have a reduced impurity content such as iron and a surfactant is used to help liberate the analyte from a stool sample. Usually, automatic mechanical or electromechanical dispensing systems are used to release the dye reagent and surfactant into the water.
