What is screening for UTI?
The two most common tests to detect UTIs are a urinalysis and a urine culture with antimicrobial susceptibility testing: Urinalysis: A urinalysis is a group of physical, chemical, and microscopic tests on a sample of urine. These tests look for evidence of infection, such as bacteria and white blood cells.
Can you have bacteria in urine without infection?
In asymptomatic bacteriuria, large numbers of bacteria are present in the urine. However, the person has no symptoms of a urinary tract infection (asymptomatic means without symptoms). It is not clear why the bacteria don’t cause symptoms.
