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

If indirect immunofluorescence assay (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 suggest amphiphysin antibody, then amphiphysin immunoblot is performed at an additional charge.

 

If client requests or if IFA patterns suggest CRMP-5-IgG, then CRMP-5-IgG Western blot, ACh receptor (muscle) binding antibody, and ACh receptor (muscle) modulating antibody are performed at an additional charge.

 

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

 

If AMPA-receptor antibody CBA is positive, then CRMP-5-IgG Western blot, ACh receptor (muscle) binding antibody, and ACh receptor (muscle) modulating antibody are performed at an additional charge.

 

If CASPR2-receptor antibody CBA is positive, then CRMP-5-IgG Western blot, ACh receptor (muscle) binding antibody, and ACh receptor (muscle) modulating antibody are performed at an additional charge.

 

If IFA pattern suggests GABA-B-receptor antibody, and GABA-B-R receptor antibody CBA is positive, then GABA-B-R receptor antibody IF titer assay is performed at an additional charge.

 

If IFA pattern suggests GFAP antibody, GFAP IFA Titer and GFAP CBA are performed at an additional charge.

 

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

 

If IFA patterns suggest PCA-1, then Purkinje cell cytoplasmic antibody type 1 (PCA-1) immunoblot is performed at an additional charge.

 

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

 

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

 

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

 

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