Culture transport (grey-top) tube
Sterile container <5 mL (for pediatric patients only)

Transport Temperature

Reject Criteria

The red & yellow swirl-top tube cannot be used for collection and transport of specimens for urine cultures. The preservative contains proprionic acid, p-hydroxylbenzoic acid ethyl ester, chlorohexidine diacetate crystalline, which inhibit bacterial growth.
Vacutainer brand culture transport (grey-top) tubes are not acceptable for urinalysis testing. The transport tubes contain boric acid, which may increase specific gravity and decrease pH results.
