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?
