What does VGKC Antibody measure?
Contains 2 testsThe VGKC Antibody test measures the presence and concentration of antibodies directed against VGKC-associated proteins in the blood. It specifically includes antibodies to CASPR2 and LGI1, which are important markers for autoimmune neurological disorders. These antibodies indicate that the immune system is mistakenly attacking nerve cells, which can disrupt normal nerve signaling.
Elevated VGKC antibody levels may suggest autoimmune neurological disorders such as limbic encephalitis, Morvan’s syndrome, or neuromyotonia. Detecting and quantifying these antibodies helps doctors confirm the diagnosis, guide treatment strategies, and monitor the effectiveness of immunotherapy. Low or undetectable levels typically indicate that VGKC-mediated autoimmune activity is unlikely.
