Hawaii requires a negative Covid test presented on arrival, or else you have to go into quarantine. But not any test will do, for instance if you got your test at the world-renowned Mayo Clinic that won’t be accepted because Hawaii only accepts tests on its list of trusted testing partners.
Except that isn’t really true, because there are several tests Hawaii accepts which aren’t on the list. So you might forgive two young women who flew from Raleigh to Hawaii with their negative test results in hand – only to discover that the results wouldn’t be accepted because they weren’t from a provider on Hawaii’s list.
