I've been doing the rounds of consultants and blood tests since I hopped on the AMA bandwagon nearly two years ago, and somewhat frustratingly, my AMA has been been a weak positive for the three blood test done through my GP, and negative twice when done through Queen Elizabeth hospital. It's frustrating because QE have a more sensitive lab test than my GP's lab test, and they would be able to tell the type of AMA if the blinking thing was positive at the time. ARRRRGH! My IgM has been consistently raised which is why QE are keeping me on their books instead of discharging me, and this year my ANA has become weakly positive, though is negative for the nasty version of PBC (GP210 and SP100), for which I am grateful. Due to normal LFTs, I've not got an official PBC diagnosis and am not on Urso.
I'm just ignoring it for now, but was curious to know if anyone was in a similar boat. For those of you with postive AMA but normal LFTs, do you also have raised IgM? Has anyone progressed with a vacillating AMA?
