The patented construction of the Chemstrip Urine Test Strips includes absorbent pads underlying the reagent pad, held in place by a mesh laminate overlay, rather than adhesive. This facilitates absorbency and rapid diffusion of the sample, prevents chemical runover onto adjacent strips, and provides easy-to-read, uniform, distinct color changes. Evaluation of results is always clear and reliable, thanks to the easy-to-read, vertical color scale on the vial label, which perfectly matches reaction colors on the test strip pads. Chemstrip urine tester strips test the following nine substances in the urine: •Bilirubin •Blood •Glucose •Ketone •Leukocyte •Nitrite •pH •Protein •Urobilinogen
