A dipstick test checks for: Acidity (pH). The pH level indicates the amount of acid in urine. The pH level might indicate a kidney or urinary tract disorder. Concentration. A measure of concentration shows how concentrated the particles are in your urine. A higher than normal concentration often is a result of not drinking enough fluids. Protein. Low levels of protein in urine are typical. Small increases in protein in urine usually aren't a cause for concern, but larger amounts might indicate a kidney problem. Sugar.

As with sugar, any amount of ketones detected in your urine could be a sign of diabetes and requires follow-up testing. Bilirubin. Bilirubin is a product of red blood cell breakdown. Usually, bilirubin is carried in the blood and passes into your liver, where it's removed and becomes part of bile. Bilirubin in your urine might indicate liver damage or disease.
