Shipping Instructions


Ship specimens refrigerated (if less than 72 hours from collection to arrive at MCL) or frozen (if greater or equal to 72 hours from collection to arrive at MCL).



Specimen Required


Specimen Type: Nasopharyngeal (NP), nasal mid-turbinate, or nares/nasal swab

Supplies: Swab, Sterile Polyester (T507)

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

Media should not contain guanidine thiocyanate (GTC).

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

Specimen Volume: Entire specimen with a minimum of 1.5 mL (maximum 3 mL) of transport media.

Collection Instructions:

1. Collect specimen by swabbing back and forth over nasal 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.

 

Specimen Type: Nasopharyngeal aspirate or nasal washings

Container/Tube: Sterile container

Specimen Volume: Minimum of 1.5 mL

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


Useful For

Detection and differentiation of coronavirus disease 2019 (COVID-19) illness (due to severe acute respiratory syndrome coronavirus 2: SARS-CoV-2) and influenza A and B viral infection in a single test using upper respiratory tract specimens

 

See following websites on indications and recommendations for testing:
