Take photos now if you have not already. The "ring" rash is erythema migrans, which is diagnostic for Lyme disease. You definitely got at least one tick-borne infection from that tick, most likely more than one. I'm glad you are getting treatment already, but definitely find an LLMD fast for more full-spectrum antibiotics, at least several more weeks. You're right that the Quest test won't be helpful, so go with an IGenex panel that detects multiple tick-borne infections, or just continue treating. Early Lyme is very treatable, if you act fast and do it right. But that "bullseye" rash means you have it - no testing required!
Good luck!
