Urine test. Urine test strip being compared to the results chart on the testing kit bottle. The sample being tested is at upper right. This strip contains three test areas designed to change colour to indicate a positive or negative result after being dipped in urine. The colours displayed can then be compared to a results chart on the testing kit. This test indicates the pH, protein level, and glucose level, in the urine. High levels of glucose and protein in the urine can be an indication of diabetes. High protein levels can indicate damage to the kidneys. This sample has slightly elevated levels of glucose.
