Clinical urine tests
Clinical urine tests are various tests of urine for diagnostic purposes. The most common is a urinalysis (UA), one of the most common methods of medical diagnosis. The word is a portmanteau of the words urine and analysis.
Other are urine culture (a microbiological culture of urine) and urine electrolyte levels.
