Question: Where laboratories can obtain viral transport media (VTM) for SARS-CoV-2 testing?

section_headers: For All Laboratories: Accessing Laboratory Testing
I can’t find viral transport media (VTM) for SARS-CoV-2 testing. What are my options?
section_content: Public health laboratories can order VTM through IRR, as noted above.
Clinical testing laboratories should acquire VTM from commercial
sources.
Public health and clinical laboratories can also create their own VTM if they
are unable to order it. In response to VTM shortages, CDC has posted a 
standard operating procedurepdf icon to create VTM for laboratories. Saline is also an
acceptable transport media for some COVID-19 viral assays, including the CDC
EUA. Check the Instructions for Use with the EUA Assayexternal
icon to see which transport
media is acceptable.

Reviewer feedback on this answer:
The answer is a good response to the question.
This is a pretty good answer that does address the question being asked. It doesn't go in a lot of detail after that but it does tell you where you can get the VTM from

Can laboratories use specimen collection devices other than those listed in the manufacturer’s instructions or EUA (e.g., swabs) for SARS-CoV-2 testing?
section_content: According to FDA, when one entity establishes equivalent performance between
parallel testing of the same specimens with the new and original components
(including viral transport media [VTM]), and FDA’s review of the validation
data indicates that it could be applicable to modifications of other tests
with an authorized EUA, FDA will post this information on its website so that
other laboratories can refer to the validation for their testing. Then, other
laboratories do not need to conduct their own bridging study for the same
modification. For additional information regarding FDA’s policy for
modification, see FDA’s frequently asked questionsexternal
icon website.

Reviewer feedback on this answer:
The answer is about testing, but not the specific inquiry in the question.
This mentions VTM but doesn't go into any detail about where labs can get this from which is what was being asked. Feels like there could be more information on this one to make it better

My facility created a laboratory-developed test (LDT) to detect SARS-CoV-2. We need to have the first five positive and negative specimens confirmed. Can we send these specimens to CDC?
section_content: Laboratories using an LDT to detect SARS-CoV-2 should confer with their state
public health laboratory for assistance. If the state public health laboratory
cannot assist, contact respvirus@cdc.gov.

Reviewer feedback on this answer:
The response partially answers the question but does not specifically answer it.
This doesn't really answer anything from the question. It's talking about labs using some acronym that wasn't in the question and provides only an email address to ask for more information
