-
Immunoassay reagents intended to perform qualitative and/or quantitative analyses on a body fluid sample (e.g., serum) to determine the neuron-specific enolase (NSE) enzyme (also known as phosphopyruvate hydratase) as a tumor marker. A high level of NSE is associated with tumors of neuroendocrine origin. It may be used as a moderately sensitive and specific marker for monitoring pediatric neuroblastoma, hemophagocytic lymphohistiocytosis, and small cell lung cancer (SCLC).
