And no, we don't usually do any confirmatory testing. We go with what the kit says. For the 'send out' COVID tests, ours are just a simple inside the nose swab (not the DEEP one) that gets sent to Labcorp for a 2-3 day turnaround. I have no idea what that costs, we have nothing to do with it. If someone wants a 'confirmatory' test, this would be what we would do, but it isn't any more accurate as far as I know than the in-office test.
