Regardless of what the SXM website says, I know that SXM has been accepting home tests by
Everlywell.. (That's a link.) These are nasal-swab tests, and results are available within 24-48 hours. The test is mailed to you. As I understand it, the test comes with a colored brochure on how to administer the test; there's also a video on their website. The test comes with a label for return. You are to return your test the same day it's taken via Fedex. This lab also provides a receipt that you can submit to your insurance company.
