UTI Pathway - Urine Collection and Interpretation

  • The diagnosis of UTI is made on the basis of a quantitative urine culture in addition to pyuria and bacteriuria.

  • A clean specimen is required for the diagnosis of UTI.

  • A clean catch urine is an alternative to catheter or supra-pubic collection in non-toilet trained children. This method relies on caregiver co-operation and alertness and requires the infant or young child to spend some time without a nappy.

  • Bag urines are useful as a screening test only.

  • Do not send bag urines to laboratory for culture: Bag specimens have an unacceptably high rate of contamination and may lead to unnecessary and invasive. investigations. They can be used to exclude an infection but not to diagnose it.

  • Urine collected in the bag should be tested with a urine dipstick for leucocytes or nitrates. If the dipstick is positive, obtain a definite urine sample.

  • Leucocytes can be found in the urine with any febrile illness and are not specific for UTI.

  • Rare to find true urine infection in the absence of significant pyuria: consider asymptomatic bacteriuria or a contaminated specimen.
