Laboratory assay overview

Anti-GAD65 antibodies, anti-voltage gated potassium channels (VGKC), anti-CASPR2, anti-LGI1, and anti-NMDA receptor (NR1 subunit) antibodies are found in patients with epilepsy with an acute/subacute presentation without evidence of CNS infection, toxic, metabolic, or other known cause of epilepsy, and possibly with evidence of CNS inflammation.

Verify these ranges and sources

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.

Always review your personal lab results with a licensed clinician, or track your lab history and health goals in Aumnivida.
