If indirect immunofluorescence assay (IFA) suggests ANN1S, ANN2S, ANN3S, PCAB2, PCATR, AMPHS, CRMS, or AGN1S is indeterminate, then paraneoplastic autoantibody Western blot is performed at an additional charge.
If client requests, or if IFA patterns suggests CRMP-5-IgG, then CRMP-5-IgG Western blot is performed at an additional charge.
If IFA patterns suggest amphiphysin antibody, then amphiphysin Western blot is performed at an additional charge.
If IFA pattern suggest NMO/AQP4-IgG, then NMO/AQP4-IgG CBA is performed at an additional charge.
If IFA pattern suggest NMDA-R antibody and NMDA-R antibody CBA is positive, then NMDA-R titer is performed at an additional charge.
If IFA pattern suggest AMPA-R antibody and AMPA-R antibody CBA is positive, then AMPA-R titer is performed at an additional charge.
If IFA pattern suggest GABA-B-R antibody and GABA-B-R antibody CBA is positive, then GABA-B-R titer is performed at an additional charge.
Native neuronal antigens: performed to confirm neuronal nuclear and cytoplasmic antibody specificities when IF screening is uninterpretable.
Recombinant human collapsin response-mediator protein‑5: performed to confirm CRMP-5-IgG when IF screening is uninterpretable. Also performed for more sensitive detection of CRMP-5-IgG.
Confirmation of GAD65 antibodies when IF screening suggests GAD65 antibodies.
