Does she have to have the surgery right now? Could she put off the surgery for a couple months? Has she had COVID? Perhaps she has antibodies? Surgeons always require a test. Is it because she doesn't want PCR test to all the way to her blood brain barrier? If so make an apptmt at CVS drive ups and go through window. She can do test herself, they say go up to the notch on the swab but nope I have never went up that far, even though they said I had to. Is she concerned that there might be other goodies on the swabs? My suggestion would be blow her nose afterward. Hope this has been helpful. Good luck
