The bloodwork that was done outside of regular labs included autoimmune assays through ImmunoSciences in California. Their panels showed autoantibodies that are not always tested for in regular Rheumatological lab workups, or if they are, I believe they have to be specifically run.

These autoantibodies were usually back within normal range or at least reduced after IVIGG's. I have no idea why the labs were run afterwards and I had so much bloodwork done, I paid no attention to when regular labs were drawn.

I had all kinds of wierd autoantibodies... I am not exactly sure how this all works with Rheumatologists or other doctors interested in looking at these, perhaps MrsD could enlighten us. I would guess there are certain labs like ANA & RA panels that test only for some specific autoantibodies that they look for when they first begin looking for autoimmune diseases.
