Method

Method Description
Immunoblot
Positive anti Hu, Yo, Ri, amphiphysin, CV2, Ma2, SOX-1, Zic4 and Tr (DNER) by immunoblot will be reflexed to tissue indirect immunofluorescence (TIIF) assay (reported based on immunoblot).
Positive anti-GAD65 by immunoblot will be reflexed to GAD65 ELISA. (Please note that GAD65 immunoblot is not optimal to screen for Anti-GAD65. If interested in testing for Anti-GAD65 specifically, consider alternative test methodology such as GAD65 ELISA.)
Anti-titin and antirecoverin antibodies are determined by immunoblot only.
Platform

Important Note: TEST ID PNPA SP
Non-interfaced clients should specify the Test ID PNPA SP when ordering this test. Not doing so will cause processing delays while ICL ascertains which test you are requesting - please refer to the notes below.
Alternate/Similar Laboratory Services: This laboratory also offers a panel that includes Autoimmune Encephalitis Antibodies and Paraneoplastic Antibodies: Comprehensive Autoimmune Encephalitis Panel (LHSC), Serum.
A similar test is offered by another ICL supplier lab:
Paraneoplastic Autoantibodies Panel (LRC), Serum
Clinical Utility
A clinical diagnosis should not be made solely based on a neural antibody result; results should be interpreted in the context of the patients clinical presentation and other ancillary test findings to ensure accurate diagnosis.
