The high temperature today, where I live, is 25 degrees F. The neighborhood mailbox cluster is across the street, outside.

The free rapid COVID-19 tests from the federal government are starting to be delivered.There are concerns cold weather could impact the results, so people who live in states with cold temperatures should keep a close watch on their mailboxes to make sure the packages aren’t left in the elements for too long.

Other problems:

Dr. Michael Mina, a proponent of at home testing, found that he had symptoms for more than 24 hours before the test turned positive. And he was doing 5 tests per day, unlike most individuals. The problem: People get sick, test, get a negative result, and don’t then isolate.

Mina also says that many people are doing cluster or group tests, thinking they could save money by swabbing all the kids with one swab and then running a test. This is a bad idea for many reasons but if the first kid is sick, then it spreads the infection to the rest of the kids.

Mina says many are storing the kits in the refrigerator. That is okay, but they must warm up to room temperature before use or they risk erroneous results.

Some people store the test kits in their car – and in warm climates, this risks exceeding the maximum storage temperature.

The effect of all this is that DIY testing might not accomplish a lot.
