Testing Algorithm Delineates situations when tests are added to the initial order. This includes reflex and additional tests.
If indirect immunofluorescence assay (IFA) (ANN1C, ANN2C, ANN3C, PCA1C, PCA2C, PCTRC, AMPHC, CRMC, AGN1C) is indeterminate, then paraneoplastic autoantibody Western blot is performed at an additional charge.
If IFA patterns suggest CRMP-5-IgG, then CRMP-5-IgG Western blot is performed at an additional charge.
If IFA patterns suggest GAD65 antibody, then GAD65 antibody radioimmunoassay is performed at an additional charge.
If IFA patterns suggest neuronal voltage-gated potassium channel-complex autoantibody, then VGKC-complex antibody IPA is performed at an additional charge.
If VGKCC is greater than 0.00 nmol/L, then LGI1-IgG cell-binding assay (CBA)and CASPR2-IgG CBA are performed at an additional charge.
If IFA patterns suggest amphiphysin antibody, then amphiphysin Western blot is performed at an additional charge.
If IFA pattern suggests NMDA-R, then NMDA-R antibody CBA and/or NMDA-R titer is performed at an additional charge.
If IFA pattern suggests AMPA-R, then AMPA-R antibody CBA and/or AMPA-R titer is performed at an additional charge.
If IFA pattern suggests GABA-B-R, then GABA-B-R antibody CBA and/or GABA-B-R titer is performed at an additional charge.
If IFA pattern suggests DPPX, then DPPX antibody CBA and DPPX titer is performed at an additional charge.
If IFA pattern suggests mGluR1, then mGluR1 antibody CBA and mGluR1 titer is performed at an additional charge.
