Specimen Collection Criteria
Collect urine in a vacutainer tube with boric acid preservative.
Minimum urine volume: 3-4 mL.
Rejection Criteria
Quantity not sufficient, specimens that leaked during transit/biohazardous contamination risk, specimens with integrity failures when analyzed, specimens not labeled with two patient identifiers, mislabeled specimens with incorrect patient information and/or inaccurate collection date/time, specimens received at the laboratory outside of the listed stability window, specimens submitted using expired collection devices, specimens submitted using incorrect collection devices
Specimen Validity and Retention
Urine (Boric Acid) Stability:
Room Temperature (20-25°C): 48 hours
Refrigerated (2-8°C): 72 hours.
Frozen (-20° or below): Unacceptable.
Specimens retained for 3 days after testing
Courier Transportation
Transport specimen at room temperature (20-25°C) or refrigerated (2-8°C). Refrigerated transport is preferred.
Clinical Utility
Signs and symptoms of a potential urinary tract infection. Infectious disease testing to assist with diagnosis.
Special Notes
Urine Culture & Sensitivity testing can only detect and identify aerobic, non-fastidious bacteria known to be UTI pathogens. This test does not detect anaerobic bacteria or yeasts.
