Useful For

Detecting 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 and IFA titer will be performed at an additional charge.
