🧠 AMPA Receptor Antibody – GluR1 & GluR2 (IFA)
Test Code: AUTO14 (You can assign your internal code)
Method: Indirect Immunofluorescence Assay (IFA)
Sample Type: 🧫 CSF (preferred) or Blood (serum)
Reporting Time: ⏱ 10–14 days
Home Collection: ✅ Available
🔍 What This Test Detects:
The AMPA receptor antibody test detects autoantibodies against AMPA-type glutamate receptors (GluR1 and GluR2 subunits). These antibodies are linked with autoimmune encephalitis, a condition where the body attacks brain receptors.
🧬 Clinical Purpose:
Used to diagnose Autoimmune Limbic Encephalitis and other autoimmune neurological syndromes, especially in patients with:
-
Rapid-onset memory loss
-
Seizures
-
Personality changes
-
Sleep disturbances
-
Confusion or hallucinations
⚠️ When to Suspect:
-
Subacute memory impairment
-
Psychiatric symptoms (aggression, paranoia)
-
Temporal lobe epilepsy-like seizures
-
Suspected paraneoplastic encephalitis (esp. with lung, breast, or thymic tumors)
🧑⚕️ Clinical Usefulness:
-
Helps confirm antibody-mediated encephalitis
-
Often used alongside other tests: NMDA, GAD65, GABA-B, CASPR2
-
May help detect underlying cancers
