A urinalysis is simply an analysis of the urine. It is a very common test that can be performed in many health care settings, including doctors' offices, urgent care facilities, laboratories, hospitals, and even at home.

A urinalysis test is performed by collecting a urine sample from the patient in a specimen cup. Usually only small amounts (30-60 mL) may be required for urinalysis testing. The sample can be either analyzed in the medical clinic or sent to a laboratory to perform the tests. Urinalysis is abbreviated UA.
