I tested positive for AMA-M2 back in Oct. and it was a 68. I had a biopsy this past Jan. and it showed a fatty liver but no PBC. The liver Dr. Still wants to monitor my bloodwork and he wants to see me back in a year. I also had elevated alpha Feta protein and C-Reactive Protein. The pathology report mentioned that it could be early in disease process or where the biopsy was taken. Anyway, I feel like it hasn't been totally excluded completely and that I'm still waiting for the ball to drop. I had my GP retest my AMA M2 to see if it is still positive and it was 69.7, so still about the same. when the Dr. mentioned false positive my first thought was lab error. So, my question is could he mean false positive as in I carry the antibody but something else caused the elevation like the fatty liver etc. or is he referring to a lab error? What is he not telling me...maybe that it's only a matter of time or do some folks just carry the antibody and never get the disease. He did say that sometimes the tests were either .5% or 5% false positives not sure which, any advice would be appreciated. I've been feeling pretty sluggish as of late and not sure what to blame it on. Thanks!
