Neuron-Specific Enolase Immunostain, Technical Component Only
Use
Neuron-specific enolase (NSE) is expressed in neuronal or neuroendocrine cells, such as neurons in the brain, ganglion cells in the wall of the gastrointestinal tract, nerves, and islet cells of the pancreas. It can be used to confirm neuroendocrine differentiation in tumors such as carcinoids. This immunohistochemical stain is useful for characterizing neuroendocrine differentiation in tumors, aiding in the diagnosis and classification of neuroendocrine neoplasms.

Limitations
The test does not include pathologist interpretation, only technical performance of the stain. If interpretation is required, order PATHC / Pathology Consultation for a full diagnostic evaluation or second opinion of the case. The positive and negative controls are verified as showing appropriate immunoreactivity. Interpretation should be performed in the context of the patient's clinical history and other diagnostic tests by a qualified pathologist. Age of a cut paraffin section can affect immunoreactivity. Stability thresholds vary widely among published literature and are antigen dependent. Best practice is for paraffin sections to be cut within 6 weeks. Unsuitable glass slides can result in inconsistent staining due to poor slide surface chemistry.
