Six months ago, my AMA was positive (25.6).
I just recently saw the liver specialist, who reran my blood work and just posted my AMA as negative. My follow up is in 3 weeks, so I'll have to ask the doc about it then.
(I am also positive ANA, so I'm not sure that it was a lab error or not since I have some other autoimmune issues going on).
Anyone have their AMA be positive, then negative? If so, what did your doctor say about it?
