Bulls Eye rashes and Lyme?

Are all bulls eye rashes indicative of Lyme disease or its co-infections?

Has anyone seen a case where someone had the bulls eye rash but wasn't Lyme related?.

Do you really need a blood test to prove it is Lyme if there is a bulls eye rash visible on the body.? I guess blood work becomes important in the absence of a bulls eye rash.

I would add that treatment should be based on symptoms AND diagnostic tests to rule out similar conditions. If someone stumbles in with Lyme-like symptoms, they should have bloodwork done to clear them of Celiacs and some other diseases as well. I'm pretty sure my LLMD won't treat patients until they've had all the other conditions ruled out, including an MRI to check for MS lesions. If you're going to give someone months upon months of destructive antibiotics, you at least want to be pretty sure they're going to be helpful first.

Lyme still (unfortunately) must be a clinical diagnosis in some cases, but there are mitigating steps you can, and should, take to rule out other possibilities.
