The seven liver tests do not detect hepatitis B. The seven liver tests mainly check whether the liver is damaged. The seven liver tests include liver enzyme test, bilirubin test, and albumin test, which can indicate whether the liver is damaged or not. However, there are many causes of liver damage, not only hepatitis B virus infection, but also viral infections such as hepatitis A, hepatitis E, hepatitis C, hepatitis D, or other causes such as drug, alcohol, autoimmune, toxic and other causes of liver damage, so it is not possible to determine whether you have hepatitis B through liver function tests. If you want to know whether you have hepatitis B, you can have a hepatitis B two-to-one test. If the hepatitis B two-to-one test indicates positive surface antigen, it can be used as a primary screening and further check the quantification of HBV-DNA of hepatitis B virus to clarify whether you are carrying hepatitis B virus.
