Movement Disorder, Autoimmune Evaluation, Serum

Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.

If immunofluorescence assay (IFA) pattern suggests amphiphysin antibody, then amphiphysin immunoblot is performed at an additional charge.

 

If IFA pattern suggests AGNA-1 antibody, then AGNA-1 immunoblot is performed at an additional charge.

 

If IFA pattern suggests ANNA-1 antibody, then ANNA-1 immunoblot is performed at an additional charge.

 

If IFA pattern suggests ANNA-2 antibody, then ANNA-2 immunoblot is performed at an additional charge.

 

If IFA pattern suggests PCA-1 antibody, then PCA-1 immunoblot is performed at an additional charge.

 

If IFA pattern suggests PCA-Tr antibody, then PCA-Tr immunoblot is performed at an additional charge.

 

If IFA pattern suggests IgLON5 antibody, then IgLON5 CBA and IgLON5 titer are performed at an additional charge.

 

If IFA pattern suggests GRAF1 antibody, then GRAF1 CBA and GRAF1 titer are performed at an additional charge.

 

If IFA pattern suggests ITPR1 antibody, then ITPR1 CBA and ITPR1 titer are performed at an additional charge.

 

If IFA pattern suggests AMPA-receptor antibody, then AMPA-receptor cell-binding assay (CBA) and AMPA-receptor titer are performed at an additional charge.

 

If IFA pattern suggests DPPX antibody, then DPPX CBA and DPPX titer are performed at an additional charge.

 

If IFA pattern suggests GABA-B-receptor antibody, then GABA-B-receptor CBA and GABA-B-receptor titer are performed at an additional charge.

 

If IFA pattern suggests mGluR1 antibody, then mGluR1 CBA and mGluR1 titer are performed at an additional charge.

 

If IFA pattern suggests NMDA-receptor antibody and NMDA-receptor CBA is positive, then NMDA-receptor titer is performed at an additional charge.

 

If IFA pattern suggests NIF antibody, then alpha internexin CBA, NIF heavy chain CBA, NIF light chain CBA, and NIF titer are performed at an additional charge.

Specimen Type Describes the specimen type validated for testing

Serum

Necessary Information

Provide the following information:

-Relevant clinical information

-Ordering provider name, phone number, mailing address, and e-mail address

Specimen Required Defines the optimal specimen required to perform the test and the preferred volume to complete testing

Patient Preparation:

1. For optimal antibody detection, specimen collection is recommended prior to initiation of immunosuppressant medication.

2. This test should not be requested in patients who have recently received radioisotopes, therapeutically or diagnostically, because of potential assay interference. The specific waiting period before specimen collection will depend on the isotope administered, the dose given, and the clearance rate in the individual patient. Specimens will be screened for radioactivity prior to analysis. Radioactive specimens received in the laboratory will be held 1 week and assayed if sufficiently decayed, or canceled if radioactivity remains.
