Hi Becky,
I was curious what that test was also. I was diagnosed in 01 and had a positive result from the blood work, but I know that I didn't have that test. In 03, a year after the tymectomy he repeated the same blood work, which showed even higher levels than the first, which surprised him. He doesn't order lab work any longer, as he said it would serve no purpose. You are a wealth of information, thank you!
Take care,
Pat
