For the myasthenia gravis and Lambert-Eaton syndrome evaluation, testing that is always performed includes the P/Q and N-type calcium channel antibodies, acetylcholine receptor muscle binding and modulating antibodies, and striational antibody. If the acetylcholine receptor modulating antibody loss is >90% and the striational antibody is positive, then this is reflexed to the ganglionic alpha-3 acetylcholine receptor antibody and also CRMP-5 IgG testing.
