My first blood work was Neg. The second said I was positive for binding (6 months later) My bloodwork a couple of months ago showed I was positive for 4 different antibodies. I have taken Imuran, Cellcept, 60mg and 180 time release Mestinon, Prednisone and bunches of IVIG. The only results I got was the 80mg of Prednisone that stopped my double vision.
