The hepatitis B carriers need to do the following examinations regularly: 1. liver function test, which can timely respond to whether there is inflammation and necrosis of the liver, so this is the primary and most important examination. 2. liver ultrasound, which can find out whether the liver echogenicity is even, whether the size is normal, whether there are other abnormal occupying structures in the liver, and whether there are abnormalities in the portal vein system and biliary system, liver ultrasound is an irreplaceable substitute for liver function test. 3. 3. liver fibrosis index examination, many patients mistakenly think that everything is fine if liver function is normal and liver ultrasound is normal, in fact, there are many liver fibrosis formation when liver function is normal, so it is impossible to detect early fibrosis through liver function test and liver ultrasound in time, only through liver fibrosis scan or liver biopsy, but liver biopsy is rejected by many people, so liver fibrosis scan is especially important. 4. especially important.4. Methemoglobin is a sensitive indicator to detect early stage of liver cancer, so regular monitoring should be done.5. Two-to-one semi and hepatitis B viral load can further assess the size of viral load.
