    摘要: A urinalysis cassette and system that includes a toilet, into which a urinalysis cassette is inserted. The cassette is comprised of a roll of color-change-reagent strips. Each strip includes a plurality of strip sections wherein an absorbent material is imbued with color-change reagent, or onto which one or more color-change reagents are dispensed. The color-change-reagent strips are consecutive and contiguous on the roll. A cassette includes two spools arranged such that when the spools turn, the reagent strip moves from a first (source spool) to a second (waste spool). The section of the reagent strip that is between the two spools may be exposed to a urine specimen. The absorbent-material strips that have been exposed to both a urine specimen and a color-change reagent may undergo a chemical reaction. Selective-lighting illumination may be applied to absorbent-material strips that have undergone such chemical reactions to measure reflectivity of certain color wavelengths. This measurement may be expressed in terms of a digital readout, which may be displayed on a user interface.
