NSE (Neuron Specific Enolase), Serum near me in Kolkata

The NSE (Neuron Specific Enolase), Serum test measures the level of neuron-specific enolase (NSE) in the blood, an enzyme primarily found in nerve cells and neuroendocrine tissues that plays a key role in energy metabolism. When these cells are damaged, injured, or grow abnormally, as in cancers such as small cell lung cancer, neuroblastoma, medullary thyroid carcinoma, or carcinoid tumors, they release excess NSE into the blood. Elevated NSE levels may also occur in brain injury, stroke, or other neurological conditions. Normal or low NSE levels are generally not a cause for concern, but must still be interpreted alongside clinical findings and other diagnostic tests. NSE is not entirely specific; it may rise in some non-cancerous conditions as well, so doctors typically use this test in combination with imaging studies and other tumor markers to arrive at an accurate diagnosis.
