Clinical Significance

Sensory-Motor Neuropathy Antibody Panel (Ganglioside) - The presence of antibodies to the gangliosides GM1, Asialo-GM1, GD1a and GD1b has been associated with motor and sensorimotor neuropathies. High titers of antibody to GM1 are most typical of multifocal motor neuropathy; however, antibodies to other gangliosides are often present. In most cases of chronic immune neuropathies, anti-ganglioside antibodies are IgM class. IgG antibodies have been reported less often, generally associated with acute conditions. Many reports have found increased anti-asialo-GM1 antibody titers in patients with multifocal motor neuropathy, lower motor neuron disease, sensorimotor ...
