A total bile acid level of 191 μmol/L does not confirm the diagnosis of cancer. Total bile acid 191μmol/L only means that the level of bile acid in the body is high and has exceeded the reference value of 0-10μmol/L. The level of bile acid reflects the liver clearance function and is not sufficient to diagnose cancer. Elevated levels can be seen in hepatocellular damage, such as acute hepatitis, chronic active hepatitis, cirrhosis, hepatocellular carcinoma, etc., as well as biliary obstruction inside and outside the liver and portal shunt. To confirm the diagnosis of cancer, it is necessary to combine with clinical symptoms and improve tumor markers, imaging (such as abdominal ultrasound, CT, MRI, etc.) and pathology under the guidance of physicians. In some people, a transient increase in serum bile acid level can also be seen after eating, so there is no need to be alarmed. Patients are advised to identify the cause and treat it as soon as possible.
