No, you do not need a blister to do a swab (that’s with a b, not a p) test. We often swab from ulcres.The thing is, you only want a PCR swab, not a culture. And I suggest that you get it swabbed ASAP today. But before you go in, be sure the PCR is the test that they will use.
By the way, after you sent me that link, I called that organization and raised hell with the for offering this test. They acknowledged that it had been a controversial decision to offer PCR from blood and that they would once again review it. I hope they do.
