DEVICES AND FORMULATIONS FOR DETECTING, SCREENING AND MONITORING LEVELS OF CERTAIN CONSTITUENTS IN BODILY FLUIDS AND METHOD

摘要

There is disclosed a device and a method of making a device for conducting a non-invasive analysis of a bodily fluid to determine the presence and the level of a certain constituent carried by the bodily fluid. The device includes an indicator formulation capable of changing color in response to exposure to the certain constituent to provide a visible indication of the presence and the level of the certain constituent carried by the bodily fluid. The device provides a carrier substrate of a material having voids establishing a high void volume within the carrier substrate. A chromagen formulation is applied to the carrier substrate to create a chromagen-laden carrier member. Then, a selected reagent is applied to the chromagen-laden carrier member, the reagent having a particular constituent-specific formulation. The selected reagent then combines with the chromagen formulation, thereby establishing the indicator formulation within the carrier substrate in place for reception of a sample of the bodily fluid later placed upon the carrier substrate.
