It seems like the testing will be changing...

I work in a health care facility and it is taking lab Corp at least 3-4 days to get results back, plus if you have an early flight or a weekend flight that would add another day to it as you would have to have the results back the day before you leave. 72 hours before landing will not work, it will have to be a week at the minimum.

Question was just asked if all of US - PM said list of states were determined based on increase of cases and rate of infection. I'm coming from Maryland and still plan to pre-test but I won't stress with having to upload my results.
