The thread title says it all.
Here's an article that discusses their use on one's children in a going-back-to-school context, but what it says would seem to apply to anyone:https://www.msn.com/en-us/health/medical/what-to-know-when-using-at-home-covid-19-tests/ar-aaoeu5b
From it:"... at-home tests like the one Friedman used were shown to be about 85 percent accurate."
"Hundreds of companies have applied for FDA approval to sell at-home COVID-19 tests but only a handful are available over-the-counter. Most tests available at the drug store work similarly and cost about $25 for a 2-pack. They’re sold at places like CVS, Walgreens, and Target but with high demand, they aren’t always easy to find."
"The brand he used required each nostril to be swabbed about one-half to three-quarters-of-an-inch deep for 15 seconds. Then the collected sample is mixed with the provided solution."
"... at-home antigen tests are more likely to give you a false result than a provider-performed PCR test because antigen tests need more viral load present in the body to return a positive test result."
"... the results are only as good as the sample provided."

and then clicking on "images" at top of resulting screen gets some displays of particular home test products, but which, as the article states, may or may not be available because of demand.
But I suppose it's good to at least know that these tests do exist, whether or not we can get and use them, if we choose to do so.
