Question about the BinaxNow proctored test. Is it a one time test and you receive result electronically? A different Antigen test - requires initial proctored test with a self test 24 - 36 hours later and time of the test is consider the first test. The issue I have is the 48 hour rule bc I also transit through LHR to FCO. If I take the initial test, wait 24 hours for second self test - 20 hour flight time leaves me no time to spare.
