Should I undergo a viral hepatitis antibody test for high bilirubin levels?

Elevated bilirubin levels are usually recommended for viral hepatitis antibody testing. Elevated bilirubin levels may be related to factors such as viral hepatitis, biliary obstruction, hemolytic diseases, etc. Antibody testing for viral hepatitis can help clarify the presence of hepatitis virus infection. Bilirubin is a product of hemoglobin breakdown, and its elevated levels can be divided into direct bilirubin and indirect bilirubin. Viral hepatitis, such as hepatitis B or C, may cause liver cell damage and affect bilirubin metabolism, manifested as an increase in both total bilirubin and direct bilirubin. Antibody testing can determine the presence of relevant viruses by detecting specific antibodies (such as anti HBs, anti HCV) in the serum. If the antibody is positive, further evaluation should be conducted in combination with liver function, viral load, and other factors. When bile duct obstruction such as stones or tumors compresses the bile duct, direct bilirubin excretion is obstructed, and hepatitis antibody testing can assist in ruling out hepatitis factors. Hemolytic diseases are mainly characterized by elevated indirect bilirubin levels, and antibody testing is mainly used to distinguish whether hepatitis infection is present.

It is necessary to avoid behaviors that increase the burden on the liver, such as alcohol consumption and high-fat diet, and regularly monitor liver function. If the examination indicates viral hepatitis, it is necessary to seek medical attention promptly from the infectious disease department or liver disease department, and follow the doctor's advice for antiviral or hepatoprotective treatment.
