Can I take liver protection tablets before liver function examination

It is generally not recommended to take liver protection tablets before liver function examination. Liver protection tablets may affect the authenticity of liver enzyme indicators and interfere with the accuracy of physical examination results.

Liver function tests usually include indicators such as alanine aminotransferase, aspartate aminotransferase, and total bilirubin, which directly reflect the metabolism and detoxification function of the liver. The active ingredients in liver protection tablets, such as silymarin and glycyrrhetinic acid, may temporarily improve liver cell status and reduce transaminase levels through antioxidant and anti-inflammatory effects. However, this artificial intervention may mask potential liver damage. Stop using liver protection tablets 3-5 days before the physical examination to restore the liver's natural metabolic state and ensure that the test results truly reflect the liver's health status.

A small number of chronic liver disease patients who have been taking liver protection tablets for a long time should adjust their medication plan according to medical advice and not stop taking the medication without authorization. If medication is necessary for treatment, the doctor should be informed in advance of the specific medication situation. The doctor will recommend an appropriate discontinuation time based on the half-life of the medication or comprehensively evaluate the examination results in combination with the medication history. Some special liver protective drugs, such as essential phospholipids, may have a small impact on test results, but still require individualized judgment by doctors. Before the physical examination, in addition to avoiding liver protection pills, it is also necessary to fast for 8-12 hours, abstain from alcohol for 3 days, and avoid vigorous exercise. Patients with chronic liver disease should consult a doctor before discontinuing medication. If abnormalities are found during a physical examination, further evaluation should be conducted based on clinical manifestations and imaging examinations.
