Checking liver function cannot detect hepatitis B virus carriers. Liver function refers to the testing of liver functions, including various indicators such as glutamic aminotransferase, glutamic oxalacetic aminotransferase, alkaline phosphatase, transpeptidase, albumin, globulin, and albumin-to-globulin ratio. The comprehensive analysis of liver function through the above indicators reflects whether the liver cells are damaged, whether the bile acid metabolism is normal, and how the reserve capacity of the liver is, and whether hepatitis B virus infection cannot be detected through these indicator tests. If you want to detect whether hepatitis B virus infection, only check hepatitis B five to clarify or check hepatitis B virus DNA, check liver function if found abnormal liver function, often need to further check hepatitis B five, hepatitis C, hepatitis A, hepatitis E, etc., may cause liver function elevated causes, the most common of which is hepatitis B virus infection.
