Use
This test aids in diagnosing sensory neuropathy in patients where malignancy is suspected, excluding plasma cell dyscrasia. It includes detection of antibodies such as SGPG IgM, MAG IgM, and Purkinje Cell/Neuronal Nuclear IgG. Positive results could indicate active demyelination in peripheral neuropathy or paraneoplastic neurological disorders associated with certain cancers.
