GM1 Antibody, IgG 5 IV 0-50
GM1 Antibody, IgM 2 IV 0-50
INTERPRETIVE INFORMATION: Ganglioside (GM1) Antibodies,
IgG and IgM
29 IV or less: Negative
30-50 IV: Equivocal
51-100 IV: Positive
101 IV or greater: Strong positive
Ganglioside antibodies are associated with diverse peripheral
neuropathies. Elevated antibody levels to ganglioside-monosialic
acid (GM1) are associated with motor or sensorimotor neuropathies,
particularly multifocal motor neuropathy. Anti-GM1 may occur as
IgM (polyclonal or monoclonal) or IgG antibodies. These antibodies
may also be found in patients with diverse connective tissue
diseases as well as normal individuals. These tests by themselves
are not diagnostic and should be used in conjunction with other
clinical parameters to conf
irm disease.

GD1b Antibody, IgG 13 IV 0-50
GD1b Antibody, IgM 7 IV 0-50
GQ1b Antibody, IgG 6 IV 0-50
GQ1b Antibody, IgM 2 IV 0-50
INTERPRETIVE INFORMATION: Ganglioside (GD1b and GQ1b)
Antibodies, IgG and IgM
29 IV or less: Negative
30-50 IV: Equivocal
51-100 IV: Positive
101 IV or greater: Strong positive
Ganglioside antibodies are associated with diverse peripheral
neuropathies. GD1b antibodies are predominantly found in sensory
ataxic neuropathy syndrome. GQ1b antibodies are seen in more than
80% of patients with Miller-Fisher syndrome and may be elevated in
Guillain-Barre syndrome patients with ophthalmoplegia. These tests
by themselves are not diagnostic and should be used in conjunction
with other clinical parameters to con
firm disease.
