Spinal tap to diagnose lyme disease
Does anyone know how reliable a spinal tap is in diagnosing lyme disease? (The doctor I was recommended to - Dr. Pat Coyle, an LLMD from Stony Brook University - said its reliable but this seems different than what a lot of people have been saying. She's sending the results to Quest Diagnostics which I've also heard was very unreliable (but which she said was great). Not sure what other tests to do though - I've already had an Elisa and Western Blot test done at Quest which came back negative (except for one band on the Western Blot). Dr. Coyle said that Lyme disease is unlikely even though I have the symptoms (swollen painful knees, neck stiffness, blurry vision, neuropathy, lower back pain, and forgetfulness/memory issues) because it is rare to have both tests come back negative. I thought lyme disease was diagnosed mainly through the symptoms through. Does anyone know whether being on antibiotics of any kind around the time of having lyme blood tests done could affect their outcome? Thanks, I'm really hoping to avoid a spinal tap since I've already had to have a Blood Patch surgery to repair a lumbar puncture from an epidural.
