"Lung cancer is one of the most common forms of cancer in the US and a leading cause of cancer deaths in both men and women. This test measures the levels of Neuron-Specific Enolase (NSE), Lipid-Associated Sialic Acid (LASA) and Carcinoembryonic Antigen (CEA) in the blood to aid in the diagnosis of lung cancer.Significant deviations from the normal range may require further evaluation by your physician."
