NSE17.11 indicates that the index is high, indicating the possible presence of tumor diseases, such as neuroblastoma, small cell lung cancer, etc., which need to be further determined by PET-CT test. NSE refers to neuron-specific enolase, which is a specific tumor marker for neuroendocrine tumors, and its normal value ranges from 0 to 16.3 ng/m. The upper limit of the normal value may fluctuate depending on the testing institution and the method of testing, but it usually does not exceed 17 ng/m. Therefore, NSE17.11 indicates that the NSE value is high, which may be related to neuroblastoma, small cell lung cancer and other tumor diseases, and it is necessary to go to the hospital for PET-CT test in time. During the PET-CT test, patients should strictly follow the doctor’s arrangement and keep a stable mind so as not to affect the test results.
