Useful For
Reporting an end titer result for tripartite motif-containing protein 46 (TRIM46)-IgG in serum 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 the TRIM46 antibody cell-binding assay (CBA) and TRIM46 antibody IFA titer will be performed at an additional charge.
