Glutathione 113 U/L does not necessarily mean that you have liver cancer. Glutathione is a protein produced by liver cells, which exists in liver cells and is released into the blood in large quantities when liver cells are destroyed, causing an increase in the level of glutathione in the blood. For this reason, GTA is often used as an indicator of good or bad liver function in clinical practice. There are many causes of elevated ALT. Any disease that can cause destruction of liver cells can cause elevated ALT, such as acute hepatitis, cirrhosis, and drug-induced liver injury. Malignant tumors of the liver, such as hepatocellular carcinoma and cholangiocarcinoma, may also lead to elevated GLTA concentration in blood due to necrosis and rupture of cancer cells, but it cannot be arbitrarily assumed that elevated GLTA is liver cancer. In fact, some patients with liver cancer do not have elevated blood ALT levels because the cancer cells do not undergo massive necrosis and transaminases are not released into the blood in large quantities.
