Diagnostic Use Or Instructions

Choosing Clinical Laboratory Tests Wisely Guidelines:

Many tests are not clinically indicated. Symptoms of a Urinary Tract Infection include: Dysuria, frequency, urgency, loin pain, polyuria, suprapubic tenderness, flank or loin pain and fever (in the absence of an alternative source for fever. Symptoms of UTI do NOT include cloudy or smelly urine.

Half of urine samples have significant contamination so are unhelpful and put the patient at risk of unneccessary and inaccurate treatment.  Coach the patient in how to collect a clean MSU.

BPAC says: People with symptoms of uncomplicated UTI do not require a urine culture. 

  • Urinalysis or culture should not be performed if there is no clinical evidence of urinary tract infection (UTI). Pregnant women and prior to urological surgery are the two exceptions to this rule.

Follow up testing

  • Follow-up testing of positive urine cultures after treatment is not indicated in the absence of persistent clinical symptoms.

Only repeat a urine culture within 24 hours if the previous sample was contaminated and the patient and the patient has not started antibiotics.

A note on the elderly

People with catheters

  • Do not request a CSU unless a catheterised patient has features of sepsis.
  • Do not send urinary catheter tips for culture.
  • Do not send urine from a catheter bag

Catheter colonisation is the norm; treatment is only indicated if a patient has features of sepsis. CSUs frequently show polymicrobial colonisation and seldom establish a diagnosis of UTI.
