Specimen Required


Preferred

Specimen Type: Nasopharyngeal (NP), nasal swab

Supplies: Swab, Sterile Polyester (T507)

Container/Tube: Universal transport media, viral transport media, or equivalent (eg, Copan UTM-RT, BD VTM, M4, M4-RT, M5)

Media should not contain guanidine thiocyanate (GTC), such as Abbott Multi-Collect Specimen Collection Kit, Copan eNAT, PrimeStore MTM.

For more information on alternative transport media, see www.fda.gov/medical-devices/emergency-situations-medical-devices/faqs-diagnostic-testing-sars-cov-2

Specimen Volume: Entire collection with a minimum of 1.5 mL (maximum 3 mL) of transport medium

Collection Instructions:

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

2. Swab must be placed into transport medium. Swab shaft should be broken or cut so that there is no obstruction to the sample or pressure on the media container cap.

3. Do not send in glass tubes, vacutainer tubes, or tubes with push caps.

4. Do not overfill with more than 3 mL total volume of media.

Additional Information: Do not aliquot into viral transport media, glass tubes, vacutainer tubes, or tubes with push caps.
