Container/Tube
Preferred: Swab in viral transport media (UTM).
Acceptable:
Collection Volume:
- Obtain a vial of universal/viral transport medium (UTM) with collection swab from Pyxis or supplied by St. Louis Children's Hospital Lab (call lab at 314-454-6130 or 314-454-4268 to obtain).
- Collect fluid by swabbing the buccal cavity (the space between the cheek and the teeth) as below.
