I recently had a test for measuring levels of GAD (which came back abnormal). I had extremely high levels of GAD. I begin IVIg therapy soon. He also tested me for lupus, lyme disease, rheumatoid arthritis, and cat scratch fever. He wanted to rule out all possible things. I am very concerned about the lupus test, however, I've had the typical butterfly rash on and off for years, and didn't realize what it was until my sister in law pointed it out (was a nurse).

If you are concerned, I would request further testing .
