MG antibody question?
I have a question about MG antibody ranges and false positives. I tested positive for the ACHR modulating antibodies (56% with normal range being 0-20%) and positive for the striational muscle antibodies (1:120 with normal being <1:60).
Does anybody know if its possible to get results like that without having MG? The neuro I just saw told me not to worry about these labs. He seemed annoyed that another doc had turned up these labs and said not to give them another thought.
I'm hesitant to ignore the labs, but I don't know much about MG tests and the possibility of false positives. Do these antibodies confirm a diagnosis? Is there anything else that could make these antibodies turn up positive? Does anyone know what a common range is for an MG-er to have on these labs? (aka, am i only "slightly" positive on these?)
Thanks for any thoughts
Mandy
