Elevated levels of serum NSE are reported in patients with small cell carcinomas primarily of lung origin. Patients with neuroblastomas may also have high levels of NSE. Serum NSE can be used to monitor recurrence or progression of tumor in these cancer patients. Daily serial monitoring of serum NSE may also be used in comatose patients to assess neuronal damage. High NSE levels in comatose patients at 24hr and 48hr post cardio-pulmonary resusitation have been associated with poor outcome. Hemolysis can cause false positive results
