Specimen Collection Criteria

Collect: A random urine specimen in a screw-capped container (preferred) or other sterile collection container. Minimum is 10 mL for both pediatric and adult patients.

Physician Office/Draw Specimen Preparation

Maintain specimen refrigerated (2-8°C or 36-46°F) prior to transport.

Preparation for Courier Transport

Transport: Urine, refrigerated (2-8°C or 36-46°F). (Minimum: 10 mL for pediatric and adult patients.)

Rejection Criteria

  • Specimens not collected and processed as indicated.
  • Urine Vacutainer® tubes. Urine received in a glass or plastic tube with a rubber stopper may contain insufficient sample volume, preclude confirmatory testing, and give rise to contaminants and artifacts.
