Urine culture, pedi bag (Edmonton/Central/North)
Back to List
Test Name:
Urine culture, pedi bag (Edmonton/Central/North)
Organism(s)/Disease(s):
Urinary tract infection (UTI)
Body Source(s):
Urine, Pedibag
Clinical Prerequisite(s):
Provision of relevant clinical information is important to ensure a clinically relevant result

  • State specimen source - Specify Pedibag urine
  • State current/proposed antibiotic therapy and start date
  • Provide relevant clinical history.  State symptoms, signs, and risk factors for UTI
  • Provide any antimicrobial allergies
  • Because pedibag urines are prone to high rates of contamination with perineal flora (up to 50%), a positive culture should be confirmed by a suprapubic aspirate or in/out (straight) catheter specimen.  A negative result rules out UTI (Reference:  Choosing Wisely:  Pediatric Infection Disease Recommendation).

    The diagnosis of Urinary Tract Infection (UTI) is CLINICAL, based on symptoms and signs, NOT laboratory testing. 

    Urine should be sent for culture only AFTER there is a strong clinical suspicion of UTI, to find the causative bacterium and its antibiotic susceptibilities

    The role of urine culture is to guide the selection of antibiotic therapy

    Urine MUST be collected BEFORE starting antibiotics

    Preferred Collection Device/Tube Type:
    Sterile 60 mL plastic container (orange-top).
    Collection Device/Tube Type:
    BD Vacutainer (blue-top) urine culture collection cup
    BD Vacutainer (grey-top) preservation tube
    Collection Instructions:

    1.  For hospital, continuing care facilities, and home collections by healthcare workers:
     - Refer to BD Vacutainer® Urine Collection Kit video
     - Transfer urine to grey-top tube IMMEDIATELY after collection
     - Submit grey-top tube only.  Dispose of blue transfer device according to your facility's policy

    2.  For home collections by parent/caregiver or in community clinics:
     -
    Collect specimen using appropriate instructions
     - Place in sterile orange-top container
     - Refrigerate specimen if not being delivered directly to the lab after collection
     - Specimen should be delivered to any outpatient laboratory or a Patient Service Center within 2 hours

    Handling/Storage Comments:

    Urine submitted in GREY-TOP tubes can be stored and transported at room temperature

    Urines submitted in ORANGE-TOP sterile containers MUST be refrigerated after collection and transported with an ice pack to prevent falsely high bacterial counts

    Delivery to the laboratory should be as soon as possible (or within 2 hours) to expedite the result
