Negative
Interpretation
Seropositivity for septin antibodies by indirect immunofluorescence is consistent with a diagnosis of autoimmune disease of the central nervous system. Cell-binding assay (CBA) testing for septin-5 IgG is required to confirm the diagnosis. Seropositivity for septin-5 IgG by CBA confirms a diagnosis of autoimmune disease of the central nervous system.
