Container

Universal transport media, viral transport media, or equivalent (eg, Copan UTM-RT, BD VTM, MicroTest M4, M4-RT, M5)

Collection

1. Collect specimen by swabbing back and forth over nasal or pharyngeal mucosa surface to maximize recovery of cells.

2. NP and OP swab specimens may be combined at collection into a single vial of transport media but only one swab is required for analysis.
