What should not be in urine?

Of the substances tested for in a urinalysis, many of them should not be present at all. These are protein, glucose, nitrites, ketones, bilirubin, urobilinogen, red blood cells, and white blood cells. Sometimes such insignificant amounts are detected that the results aren’t meaningful, so the test is still considered negative.  

Urine is designed to rid the blood of waste products and extra fluid, filtered through the kidney.  When everything works as it should, no extra substances are present, and the urine is a clear yellow color. The urinalysis is a quick, inexpensive way to test for the presence of lots of things at once, and can give indicators that guide the doctor to select more in-depth testing and treatment.
