Specific antibodies found in association with GBS include the following:

  • Antibodies to GM1: Frequently found in the sera of patients with the acute motor axonal neuropathy (AMAN) or acute demyelinating polyradiculoneuropathy (AIDP) variants of GBS

  • Anti-GM1 antibodies: Elevated titers are closely associated antecedent C jejuni infections

  • Anti-GQ1b antibodies: Found in patients with GBS with ophthalmoplegia, including patients with the Miller-Fisher variant

Other antibodies to different major and minor gangliosides also have been found in GBS patients.
