Anti-NMDA Receptor Encephalitis IgG Antibody
Measures IgG antibodies against NMDA receptors in serum, linked to autoimmune encephalitis and other neuroinflammatory conditions. Elevated levels suggest neuropsychiatric symptoms such as seizures, confusion, and memory loss. Important for diagnosing paraneoplastic or autoimmune encephalitis.
Anti-NMDA Receptor Encephalitis IgG Antibody Test in Dankuni Overview
No special preparations needed
- Anti-nmdar Igg Antibody
- Specimen
- Initial Dilution
This test detects the presence of IgG antibodies against NMDA (N-methyl-D-aspartate) receptors, which are involved in brain signaling. These antibodies are associated with autoimmune encephalitis, a serious neurological condition.
Anti-NMDA receptor encephalitis can cause psychiatric symptoms, seizures, memory loss, confusion, and autonomic dysfunction. Early detection through this test allows for timely immunotherapy and better clinical outcomes.
The test is typically done using a cerebrospinal fluid (CSF) or serum sample. It uses cell-based assays or immunofluorescence techniques to detect the specific antibodies.
No fasting or preparation is required, but if a lumbar puncture is needed to collect CSF, your doctor will guide you on the pre-procedure protocol.
Results usually take 7–10 days. A positive result supports the diagnosis of autoimmune encephalitis and prompts further neurological evaluation.
