(16).jpg "A Trivia Quiz On Urinalysis Problem!")
A urinalysis is simply a test of the urine. It is typically done to detect any health issues that may be occurring that affect the urinary system. It involves checking the color and content of the urine. An abnormal urinalysis can explain an underlying health problem. If you want to know more about urinalysis, this is the quiz for you.
