The anti-SGPG Autoantibodies ELISA by BÜHLMANN is a semi-quantitative assay for determining IgM antibodies against SGPG. Anti-SGPG antibodies have a wider spectrum than anti-MAG antibodies: some patients which are anti-SGPG positive are negative for anti-MAG antibodies. Therefore, combined testing enhances sensitivity. The presence of anti-MAG/anti-SGPG antibodies is suggestive of a ...
The anti-MAG Autoantibodies ELISA has outstanding sensitivity and specificity. In a study with 68 involved patients, the anti-MAG Autoantibodies ELISA was considerably more sensitive compared to Western Blot (Kuijf M. et al., 2009). High titers of IgM anti-MAG antibodies are associated with sensory motor demyelinating peripheral neuropathy. The possibility of MAG antibody involvement in a ...
