Note that the 6 packs of tests are available from eMed.com. Optum.com sells packs of 2 or 3 tests if you don't see a need for 6.
Also, be aware the tests do have an expiration date - make sure they will not expire before you need to use them!
The eMed test expirations were extended for 90 days from what's marked on the package so don't throw out anything too early.
Also, keep in mind I used the eMed tests for my entry to the United States requirement with no issues.
