A laboratory examination performed on urine samples to detect the presence of bacteria is known as a urine culture test. This diagnostic procedure helps identify and determine the type of bacteria that may be causing a urinary tract infection (UTI) or other urinary system-related infections. By culturing a urine sample under controlled conditions, healthcare professionals can promote the growth and identification of any bacteria present in the sample. The results of the urine culture test aid in diagnosing and guiding the appropriate treatment for bacterial infections affecting the urinary system.
