Specimen Required
Only orderable as part of a profile. For more information see:
ENS2 / Encephalopathy, Autoimmune/Paraneoplastic Evaluation, Serum
DMS2 / Dementia, Autoimmune/Paraneoplastic Evaluation, Serum
EPS2 / Epilepsy, Autoimmune/Paraneoplastic Evaluation, Serum

Useful For
Detecting phosphodiesterase 10A (PDE10A)-IgG in serum specimens
Evaluation of autoimmune/paraneoplastic neurological syndromes among patients presenting with movement disorders and encephalopathy
Testing Algorithm
If the indirect immunofluorescence (IFA) pattern suggests phosphodiesterase 10A (PDE10A) IgG, then the PDE10A antibody IFA titer will be performed at an additional charge.

Negative
Interpretation
A positive result is consistent with phosphodiesterase 10A (PDE10A) autoimmunity that manifests with autoimmune movement disorders or encephalitis. A paraneoplastic cause should be considered.
