Methods are provided for glucose detection and quantification in urine. The methods include selecting a test device comprising a matrix impregnated with a chromogenic indicator mixture, locating the test device to promote incidental contact of same with animal urine, reading a developed indicator color after the device has been wetted with urine, and determining the animal's urine glucose concentration.

Threshold glucose detection in urine

The present invention is directed to a reagent composition for use in detection and quantification of glucose in urine comprising a first chromogenic indicator reagent combination capable of color development to indicate the presence of a lower concentration of glucose, a second chromogenic indicator reagent combination capable of color development to indicate the presence of a higher concentration of glucose, wherein the first chromogenic indicator prevents color development of the second chromogenic indicator unless the higher concentration of glucose is present, a scavenger that prevents color development of the first indicator reagent composition unless a threshold concentration of glucose is present.

Devices and test kits are provided for glucose detection and quantification in urine. The devices and kits comprise a chromogenic indicator mixture comprising a first indicator capable of color development to indicate the presence of a low-to-medium concentration of glucose, a second indicator capable of color development to indicate the presence of a higher concentration of glucose, wherein the first indicator prevents color development of the second indicator unless the higher concentration of glucose is present in the urine, and a non-chromogenic scavenger that interferes with color development of the first indicator when glucose levels are below a threshold concentration, and a carrier impregnated with the chromogenic indicator mixture.

Test devices and methods are provided for detection of feline lower urinary tract disease. The test devices comprise a matrix impregnated with a color indicator and a stabilizer wherein the indicator remains stable when exposed to ambient conditions and wherein a positive color response remains stable for a sufficient time for the color response to be observed. The test devices may be provided for use in combination with conventional cat box filler.

A unitized, one step test reagent composition, device and method is presented for the determination of phosphorus in various test sample fluids such as soil extracts. The invention is a modification of the Murphy and Riley methodology which utilizes a molybdate salt and a reducing agent to generate 'molybdenum blue' in the presence of phosphate. In addition to the molybdate salt, the test reagent composition includes a chromogenic reducing agent which contributes to the color development and a solid buffer. The composition is preferably incorporated into a matrix such as paper for ease of handling.
