Result Interpretation

Normal:< or =15ng/mL
Indeterminate:15-30ng/mL
Elevated:>30ng/mL
Elevated results may indicate the need for additional workup. Possible causes may be NSE-secreting central nervous system/leptomeningeal tumor or rapid neuronal destruction from a variety of causes. In the context of dementia, elevated results may be suggestive of Creutzfeldt-Jakob disease.
