There are a number of tests to help
diagnose urinary tract infections. The fastest and simplest test is a
, which analyzes a sample of your urine, looking for bacteria and blood cells (both white and red). If you have a urinalysis, your doctor may ask you to clean your genital area with a special cloth (to kill exterior bacteria) and to begin collecting your urine mid-stream.
Other UTI diagnostic tests may include:
, which involves growing bacteria from your urine in a lab setting to find out what type of bacteria is causing your infection, which helps your doctor choose the most effective antibiotic
Imaging your urinary tract
, which may be performed using three different tests; these tests are usually reserved for people with recurrent infections:
A CT scan of the urinary tract
An ultrasound of the kidneys and/or bladder
, which involves using an instrument called a cytoscope to see inside your urethra and bladder; it is sometimes done when people have recurrent UTIs to look for abnormalities that may be causing the infection
(if kidney infection is suspected)
(to rule out pelvic infection in women)
(to rule out prostatitis in men)
If you have
signs or symptoms of a UTI, see your doctor to get an official diagnosis and treatment.
