Autoimmune Myelopathy Evaluation, Spinal Fluid
Testing Algorithm 
Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
If indirect immunofluorescence assay (IFA) patterns suggest AGNA-1 antibody, then AGNA-1 immunoblot is performed at an additional charge.
If IFA patterns suggest amphiphysin antibody, then amphiphysin immunoblot is performed at an additional charge.
If IFA patterns suggest ANNA-1 antibody, then ANNA-1 immunoblot is performed at an additional charge.
If IFA patterns suggest ANNA-2 antibody, then ANNA-2 immunoblot is performed at an additional charge.
If IFA patterns suggest PCA-1 antibody, then PCA-1 immunoblot is performed at an additional charge.
If IFA patterns suggest PCA-Tr antibody, then PCA-Tr immunoblot is performed at an additional charge.
If IFA pattern suggest NMDA-receptor antibody, then NMDA- receptor antibody cell-binding assay (CBA) and NMDA- receptor titer are performed at an additional charge.
If IFA pattern suggest AMPA- receptor antibody, then AMPA- receptor antibody CBA and AMPA- receptor titer are performed at an additional charge.
If IFA pattern suggest GABA-B- receptor antibody, then GABA-B- receptor antibody CBA and GABA-B- receptor titer are performed at an additional charge.
If IFA pattern suggest DPPX antibody, then DPPX antibody CBA and DPPX IFA titer are performed at an additional charge.
If IFA pattern suggest mGluR1 antibody, then mGluR1antibody CBA and mGluR1 IFA titer are performed at an additional charge.
If IFA pattern suggest GFAP antibody, then GFAP antibody CBA and GFAP IFA titer are performed at an additional charge.
If NMO/AQP4-IgG FACS screen assay requires further investigation, then NMO/AQP4-IgG FACS titration assay 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.
