An assay test kit is used in a mouth rinse sample collection procedure involving collecting a mouth rinse sample from a patient. A neutrophil reactant diagnostic reagent is delivered to the rinse sample immediately after collection. Diagnostic reagents containing diammonium salts that are reactive with neutrophil enzymes are added to the sample to produce visually discernable colour change in the solution after a selected period of time. Most preferably, the reagents are selected to produce a colour change after a period of time. The reaction is then measured by comparing the resulting sample colour change by eye or mechanically to a standardized colour chart/swatch that correlates with predetermined neutrophil concentrations and/or periodontal disease levels.
