Urinalysis (or "UA") is an array of tests performed on urine and one of the most common methods of medical diagnosis. A part of a urinalysis can be performed by using urine dipsticks, in which the test results can be read as color changes.

Urinalysis can reveal diseases that have gone unnoticed because they do not produce striking signs or symptoms. Examples include diabetes mellitus, various forms of glomerulonephritis, and chronic urinary tract infections.

The urinalysis is a set of screening tests that can provide a general overview of a person’s health. Your doctor must correlate the urinalysis results with your health complaints and clinical findings and search for the causes of abnormal findings with other targeted tests (such as a comprehensive metabolic panel (CMP), complete blood count (CBC), or urine culture (to look for a urinary tract infection).
