🧠 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
