Urinalysis is a simple laboratory test done to discover any problems in your body that can appear in your urine. Most people do not know that many illnesses affect how your body excretes wastes and toxins. The excretory system takes care of removing those toxins. The lungs, kidneys, urinary tract, skin and bladder make up the excretory system. Therefore, problems with any of these things can lead to changes of urine appearance, concentration, and content.
