Hello, I am currently in Diagnostic limbo.. my initial MG panel came back negative, but now we are going to run a Musk panel, especially since I have the characteristic tongue of Musk+MG.. I have read on here that having Athena labs run the tests seems to be most sensitive, my neuromuscular dr said that he would gladly run it with that lab, however it may end up being very expensive (my insurance covers out of network labs, but not as much as in network of course). Does anyone have experience with Athena labs, their insurance not covereing it and having the MG or MUSK panel run with them- his nurse made it sound like it was going to be extremely expensive, but we really need answers and it would be nice to have more faith in the lab running the tests!!!
