Due in part to the development of multiple reagent strips (dipstix) for urinalysis, more laboratory tests are now performed each year on urine than on any other body fluid. A typical urinalysis includes tests for glucose, protein, pH, ketone bodies, bilirubin, occult (unseen) blood, urobilinogen, and specific gravity and microscopic examination of urinary sediment. Many common abnormalities can be recognized by urine studies. Urine tests are the method of choice to monitor the treatment of diabetes.
