Antibodies

After numerous blood tests, 24 hour urine test, a MRI and neurophysiology test, I was told that thyroid was normal, pituatary was normal, cortisol slightly lower than normal, high antibodies (resulting in another blood test, no results as yet). I have been told that I have carpel tunnel syndrome in both hands but that the pain in my wrist must be something else. Getting loads of info but no treatment as yet. My eyes, legs and hands still very swolen. Rheumatoid and Lupis were some words I remember being mentioned by the consultant. Please can someone explain what high antibodies signifies.
