Testing Algorithm

If immunofluorescence assay (IFA) pattern suggests amphiphysin antibody, then amphiphysin immunoblot are 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 suggest 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 GRAF1 antibody, then GRAF1 CBA and GRAF1 titer are 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 ITPR1 antibody, then ITPR1 CBA and ITPR1 titer are 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.
