Hepatitis B refers to chronic hepatitis B. The tests usually done include abdominal ultrasound, blood biochemistry and pathogenetic tests. 1. Abdominal ultrasound: abdominal ultrasound is a commonly used method in liver examination, which can help doctors to clarify the size and shape of the liver as well as the condition of important blood vessels in the liver, and it has high diagnostic value for liver cirrhosis. 2. Blood biochemistry examination: it mainly includes liver function test, which usually shows the elevation of other indexes such as alanine aminotransferase, aspartate aminotransferase, etc. At the same time, there may be the decrease of albumin, the elevation of Y-globulin, as well as the decrease of the ratio of albumin and Y-globulin or the inversion of the situation. 3. Pathogenetic examination: Hepatitis B 5 can indicate the status of hepatitis B infection, whether it is current infection, previous infection or virus carrier. In addition to the above examination, the examination items of chronic hepatitis B include blood routine, urine routine, CT, MRI, liver histopathology examination and so on.
