Home test results are compared to color charts. Some drugs change the color of urine but do not indicate disease. Some of these are chloroquine, iron supplements, levodopa, nitrofurantoin, phenazopyridine, phenothiazines, phenytoin, riboflavin , and triamterene. If the urine is of an unusual color that cannot be accounted for by food intake or medication and the urinalysis is positive, consult the health care provider. In some situations, an alkaline urine is good.
Kidney stones are less likely to form and some antibiotics are more effective in the alkaline urine.
There may be times when the acidic urine may help prevent some kinds of kidney stones and may prevent growth of certain types of bacteria. If the pH is very acidic or alkaline, you may want to discuss it with the health care provider. When blood levels of glucose are very high, some of the glucose may show up in the urine. The glucose and the ketones tests are usually done together. Large amounts of ketones may be present in uncontrolled diabetes .
