Urinary Tract Infection Diagnosis

Urinary tract infection diagnosis is made by a medical professional, confirmed by a urine culture. A urinalysis is performed to detect the presence of nitrites, leukocytes or lekocyte esterase. If a high bacterial load is found, but leukocytes are not, then contamination is likely.

If the urine culture used to test for a UTI is negative, one of the following conditions is also a possibility:

Urethritis as a symptom may suggest Chlamydia trachomatis or Neisseria gonorrheae infection.

Cystitis symptoms may be caused by interstitial cystitis (also known as IC, or painful bladder syndrome, PBS).

Dysuria in men may be related to prostatitis.

In a severe urinary tract infection, additional tests of urea and creatinine measurement may be done to determine whether renal function (kidney) has been adversely affected. Such severe infections are often associated with fever, shaking chills and flank pain.

In females, most lower urinary tract infection cases are benign and do not need extra tests. On the other hand, a young infant with a UTI should receive an imaging study such as a retrograde urethrogram, to assess the presence of absense of any congenital urinary tract anomalies. Males with urinary tract infections should also be tested further, usually by x-ray, MRI or CAT scan.
