Can ANYONE here please tell me the difference between an AMA test and an M2 test. they are not the same. I tested positive 2 times with the M2 and tested negative for AMA. My liver specialist told me that he goes by the AMA and since it was negative and I have no other abnormal liver labs or symptoms and i had an MRCP - mri of my biliary ducts and everything was normal that he thinks I DO NOT have PCB.
Is there a reason that I would have a positive M2 besides PCB? Please write back - you all know all about this and I just joined and am puzzled.
I went to the doctor complaining of upper right sided abdominal pain. That's why he tested me. Also I am ANA and smooth muscle actin negative.
