just received an email from United promoting a test you take yourself, which is valid for re-entry into the US after travelling abroad...test is done in combination with your mobile phone or computer...results in 15 minutes....but hopefully re-entry tests won't be needed for much longer, so this new product may be a little late to the party

looks to be $150 for pack of 6 tests

"DIY" COVID test
