Dr Vaughn does not take insurance if you are out of state (not sure if you are in state). He has specialized in long covid and is willing to try things. He is the only person (to my knowledge) in the US with flourescent microscopy to assess microclots. If you have them, he prescribed triple therapy (three anti-coagu­lants at once). He knows a fair bit about supplements and MCAS. He will send you for extensive labs (what should be partly covered by your insurance if you have insurance). He did a very thorough lab work up on me, checking to see if I had various autoimmune conditions, EBV reactivation, HHV6 reactivation, genetic clotting disorders, lymphocyte counts, histamine levels, endothelial health markers, etc. He has seen many with long Covid and has a wealth of personal information. He has a few nurse practitioners – I think Katie is the best.
