My state is distributing free tests at certain locations but I havent tried to find any near me. However I was picking up a prescription today and the pharmacy had a stack, selling for $9. First time Ive seen them available so I picked one up. Just in case I get worried before the federal ones arrive.

(102,361 posts)and I had checked their information on that score. If you left it out to freeze for multiple days you might have an issue, but merely overnight is not considered problematic.
While this is the storage information for the Abbott kits, additional information suggested less than a day at cold sub-freeezing temps would not be problematic. Two of mine from the state health department sat outside in 20F temp overnight, but Abbott said they could be used. Generally speaking that applies to all the test kits as per some of the reporting links below--as long as they are brought to room temperature before using..
Storage and Stability (Abbott)
The test kit should be stored at a temperature between 2-30 °C. Do not freeze the kit or its components. Note: When stored in a refrigerator, all kit components must be brought to room temperature (15-30 °C) for a minimum of 30 minutes prior to performing the test.
STORAGE CONDITIONS (IHealth test kits shipping now)
Store iHealth® COVID-19 Antigen Rapid Test in a dry location between 36-86 °F (2-30 °C).
Ensure all test components are at room temperature 65-86 °F (18-30 °C) before use. The
COVID-19 Test Card inside the foil pouch should be used within 1 hour after opening. The

(65,173 posts)The biggest concern I can see with freezing is rupturing of the reagent tube.
I looked up the chemistry of the test on soci.org.
I see nothing in there that suggest damage to the swab, card, reagents from cold.
If very cold for a long time I suppose it could alter the integrity of the gold nanoparticle suspension.
The recommendation to give time to get to, & equilibrate to, room temperature appears to be more a mass transfer concern (viscosity) than a chemical integrity issue.
Running the test cold could slow the reaction binding the protein to the antigen/nanogold, meaning it would take longer than the expected 15 minutes.
Near as I can figure, that binding is a 1st order reaction (might be zero order) so every 10°C doubles the reaction time.
But, i don't see how getting cold ruins the test, despite their warnings.

(2,015 posts)because my address is not being recognized as an apartment house. I tried calling and ordering through the automated system but it told me a kit had already been sent to this address and hung up on me. I called back and talked to a person and told her the problem, she tried entering the information and got the same result, it won't send another kit to this address (my apartment # was included but apparently that doesn't matter) so she supposedly sent me a link by email so a ticket can be issued but it's been a while and the email still hasn't shown up.
Guess I'm not getting a free kit sent to me.

(10,242 posts)I placed my order as soon as they were available. I wonder if the owner has tried ordering and if he was rejected like you.

(3,361 posts)I dunno if that's typical or not, but I was pleasantly and mildly surprised how quickly it arrived.

(58,785 posts)USPS has added thousands of seasonal employees and converted more than 40 facilities to house, process and ship the rapid tests.
The U.S. Postal Services mission to deliver 500 million coronavirus test kits has cast it in an unprecedented role in the nations pandemic response just as covid-19 infections have peaked within its own ranks and its network is under immense strain.
Online orders began rolling in this week for the free rapid tests, which are scheduled to ship by the end of the month. The agency has hired thousands of seasonal workers and converted more than 40 facilities into ad hoc fulfillment centers in what experts have called the largest disaster-relief mobilization in its 247-year history.
The stakes for the country and Postal Service could hardly be higher. Americans are still struggling to access at-home coronavirus tests as the omicron variant is driving caseloads near record highs in parts of the country.... Even if you know how to do it, its never been done before. A lot can go wrong, said one senior postal official. But if we can pull it off, wow....
Although the agency is set up to move billions of pieces of mail letters, advertisements, ballots, parcels, even cremated remains it has never managed its own off-the-shelf inventory or developed this kind of consumer-fulfillment operation.
The undertaking, as well as a separate nonpostal effort to distribute 400 million high-quality N95 masks, is part of the Biden administrations response to the omicron-powered coronavirus spike that caused nearly 9 million people to miss work in late December and early January. ...
This is not just emergency relief distribution during an emergency but study and practice for the next ones. This isn't our last pandemic or other national emergency. There are going to be others, and the USPS is learning a new role.
We love our wonderful, 247-year-old, extremely unjustly embattled postal service. Go, USPS!
