Exactly Warren. That is my fear as well.

WInterstale, all of the medical tests we use (aside from a select few) have the possibility of giving you a positive result even though you are not positive or a negative result even when you are actually positive for the disease and this depends on the test you are using. We have a couple of different types of tests for COVID. Fortunately the specificity is very high for COVID tests and therefore most positive tests are pretty accurate. However, negative tests have only been about 80-85% sensitive so a negative test is by no means a guaranteed negative. I think the specificity is as high as 96-98% though.

Hopefully that is not too technical an answer but Warren's concern is valid. It would stink to get there with a negative test, get another required test that is falsely positive and not be able to go on your charter.
