Just spoke with my Dr. again and she said that my "TIDA" (spelling??) was over 160. That, along with a positive "ANA" indicates some type of autoimmune disease but she didn't say for sure. She said she thought maybe LUPUS! She also said that it would be better to have LUPUS than MS! (go figure!!?? LOL). She is making me an apt. with a neuro. today.
