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 ANNA-1 antibody, then ANNA-1 immunoblot and ANNA-2 immunoblot are performed at an additional charge.

 

If IFA patterns suggest ANNA-2 antibody, then ANNA-2 immunoblot, ANNA-1 immunoblot, and ANNA-2 antibody IFA are performed at an additional charged.

 

If IFA patterns suggest ANNA-3 antibody, then ANNA-3 IFA is performed at an additional charge.

 

If IFA patterns suggest PCA-1 antibody, then PCA-1 immunoblot and PCA-1 IFA are performed at an additional charge.

 

If IFA patterns suggest PCA-2 antibody, then PCA-2 IFA 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 suggests amphiphysin antibody, then amphiphysin immunoblot and amphiphysin antibody IFA titer are performed at an additional charge.

 

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

 

If IFA pattern suggests NMDA-R antibody, then NMDA-R IFA titer is performed at an additional charge.

 

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

 

If IFA pattern suggests GABA-B-R antibody, then GABA-B-R IFA titer is performed at an additional charge.

 

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

 

If IFA pattern suggests mGluR1 antibody, then mGluR1antibody CBA and mGluR1 IFA titer are performed at an additional charge.

 

If IFA pattern suggests 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.
