    Here's a question I can't seem to get any Virologist to answer.

    How long is a COVID 19 throat swab viable for testing when NOT stored properly?

    The specific example

    If a covid19 throat swab sample was returned to the LAB via regular 2nd class post (2-7 days) and it took 5 days to reach the sorting office (was in sealed package but not temperature controlled) would that sample when retrieved by the lab still be a viable sample for testing?

    ie. Does it/should it be refrigerated same day etc?

    No.

    I used to work in a photo lab. Customers would try to return film, and I would have to point out to them that it could have easily been sitting on their dashboard in direct sunlight and reached a temperature well over 120F.

    There is no point in testing something a sample whose provenance you cannot verify.
    Food for thought: What would you do if it came back negative? What would you do if it came back positive?

    I will tell you what I 'did' Dave

    I immediately reported this company and what do you think the powers that be have done about it? ZERO. I'm still working on it. I just needed to know for certain what the situation was regarding how the sample was returned to the lab.
