Neuron-specific enolase 18.36 means that the test data is 18.36 μg/L, which is higher than the normal value, but whether it is serious or not needs to review the results or combine with other test indexes to determine the comprehensive judgment. The normal range for neuron-specific enolase (NSE) is <15 μg/L. It is a unique enzyme found in the nervous system, and a single elevation does not have diagnostic significance, but needs to be observed dynamically to see the long-term trend and in combination with other test results. Neuron-specific enolase is commonly used to evaluate the severity of nerve cell damage and to determine prognosis. Abnormalities can be seen in a variety of neurological disorders, such as cerebral hemorrhage, stroke, cerebral ischemia, and meningitis. It can also be used to assist in the diagnosis of small cell lung cancer and neuroblastoma, as well as for disease monitoring of tumors. Neuron-specific enolase 18.36μg/L needs to be reviewed and combined with other test results. It is recommended to go to the hospital to clarify the cause, so as to avoid delaying the condition.
