A high ferritin in a normal liver cancer quadruple test may be due to an increase in ferritin synthesized by the cancer cells, as well as an elevated level of ferritin due to the damage to the liver cells, which affects the uptake and clearance of ferritin in liver cancer patients. Ferritin is a protein that stores iron and is usually found only in small amounts in normal human serum. The normal range for ferritin is 15 to 200ug/L. If ferritin levels are significantly elevated, it needs to be taken seriously. Patients with hepatocellular carcinoma or acute or chronic liver injury may have elevated ferritin levels. Hepatocellular carcinoma cells are able to synthesize and secrete ferritin, and at the same time, hepatocytes are able to affect the uptake and clearance of ferritin, resulting in elevated ferritin levels. High ferritin should be treated promptly to control the primary disease.
