The nine tests of liver function do not include hepatitis B. The nine tests of liver function do not include hepatitis B. The items included in the nine tests of liver function are glutamate transaminase, glutamic oxalacetic transaminase, total bilirubin, direct bilirubin, indirect bilirubin, total protein, albumin, glutamyl transpeptidase, and alkaline phosphatase. The examination of hepatitis B is mainly clarified by the five tests of hepatitis B and the quantification of hepatitis B virus DNA. The nine tests of liver function and hepatitis B are both distinctly different and closely related. The nine liver function tests mainly reflect whether there is liver cell damage and the synthesis, transformation, metabolism and excretion functions of the liver. The nine liver function tests do not clarify the presence of hepatitis B lesions in patients, and patients with hepatitis B do not necessarily cause abnormalities in the nine liver function tests. Hepatitis B patients often need to have a liver function nine test clinically, and when the liver function nine test is abnormal, in many cases it is necessary to further rule out the presence of hepatitis B virus infection. The liver function test can also be an important indicator of whether a patient with hepatitis B needs antiviral therapy and the development of a treatment plan.
