The test strip defines a first region impregnated with the first medium, and a second region impregnated with the second medium. The test strip optionally includes a third medium capable of indicating the pH of the dialysate. The third medium is impregnated at a third region on the test strip. Alternatively, the test strip comprises a bicarbonate test pad attached to the first region, a glucose test pad attached to the second region, and optionally a pH test pad attached to the third region. The glucose test pad is impregnated with the first medium, the glucose test pad is impregnated with the second medium, and the pH test pad is impregnated with the third medium.Other References
