Specimen Type

Oropharyngeal (OP) collection in viral transport medium, ESwab(TM), or saline. Nasopharyngeal (NP) swabs also accepted in viral transport medium (discard OP swab included with viral transport medium), ESwab(TM), or saline. Anterior Nasal Swab in saline. OP or NP washes/aspirates in sterile cups. Bronchial washing or bronchoalveolar lavage (BAL) specimens in sterile cups.

Specimen Container

For swabs in viral transport medium or ESwab(TM): Oropharyngeal (OP) samples: swab included in viral transport medium or ESwab(TM) is acceptable for submission. Nasopharyngeal (NP) samples: use separate NP swab submitted in viral transport medium (discard OP swab included with viral transport medium or ESwab(TM)). Exact manufacturer of the swab and transport medium may vary with supply. Any swab of appropriate size and configuration with a synthetic tip can be used except for calcium alginate tips, swabs with preservatives, and swabs with wood shafts. Viral transport medium acceptable for collection of influenza specimens in 1 ml or 3 ml volumes can be used to transport swabs for COVID-19 testing. For swabs in saline: OP, NP or anterior nasal swabs may be placed in 1 to 3 mL of sterile saline (0.85 to 0.9%) in a sterile screw cap container. Do NOT use vacutainer or "pop-top" tubes. Any swab of appropriate size and configuration with a cotton or synthetic tip can be used except for calcium alginate tips, swabs with preservatives, and swabs with wood shafts. Sterile cups are acceptable for OP or NP washes/aspirates, bronchial washings, or bronchoalveolar lavage (BAL) specimens. Swab in saline in screw-top Vacuette Virus Stabilization Tube is acceptable.

Volume
