I was reading alot on Lupus and there are specific tests you can have done for Lupus not just the ANA. I honestly can't remember what they were but I can look them up if you want. I had them listed at one point and I was going to have my doctor do them. I am still very unsure about my Lyme diagnosis and was looking into other diseases.
I have a low CD-57 but I don't think that test means a whole lot. Post if you would like me to get those test names for you.
