Just a reminder, you cannot test once with a RAT.

>> A new study shows that on Day #1 the rapid antigen COVID test are only 30 to 60% sensitive, on Day #3 they are 59 to 75% sensitive and on Day #4 they are 80 to 93% sensitive. If have symptoms and you test negative on Day #1, #2 or #3, it is very important to test again on Day #4 and/or Day #5 to make sure that you have not become positive. <<
