Useful For
Reporting an end-titer result for tripartite motif-containing protein 46 (TRIM46)-IgG in cerebrospinal fluid specimens
Evaluation of an autoimmune/paraneoplastic neurological syndrome among patients presenting with cerebellar ataxia, encephalitis, or encephalomyelitis.
Testing Algorithm
If the indirect immunofluorescence (IFA) pattern suggests tripartite motif-containing protein 46 (TRIM46) IgG, then TRIM46 antibody cell-binding assay (CBA) and IFA titer will be performed at an additional charge.
