A carbohydrate antigen 19-9 (CA 19-9), a tumor marker often elevated in pancreatic and biliary cancers, and carcinoembryonic antigen (CEA), a biomarker elevated in many malignancies, were ordered to assist in diagnostic localization; the former resulted elevation at 85 units/ml (reference range: 0-37 units/ml), and the latter resulted in a normal level at 4.4 ng/ml (reference range: 0-4.9 ng/ml). The gene discussed is CEACAM5; the disease is neoplasm.
