With restrictions lifting, it won't apply everywhere, but I was scheduling pre-travel covid tests 48 hours out for PCR and 12 hours out for rapid antigen, and I almost forgot to schedule tests 11-14 days out! I was thinking about how awful it would be to test positive 12 hours out and miss the trip, especially if I was asymptomatic and may have contracted it weeks ago and be well in the clear as far as transmission and it dawned on me I had planned to schedule early tests and had forgotten to do it. At least if any of us tests positive 11 days out, we can quarantine and have time to get a doctor's note for recovery, eliminating the need for tests in some cases and explaining any positive satisfactorily with the appropriately dated positive result (and note)... but it just about slipped my mind.
I'm sure everyone is waaaay ahead of me on this, but putting it out there for those of us who may be forgetful no matter how carefully we research!
