The quantification of hepatitis B may refer to the quantification of the hepatitis B virus DNA. Because hepatitis B patients are able to detect hepatitis B virus DNA in their blood and can determine this aspect of the virus by the amount of it. If the patient is reviewed regularly, there can also be dynamic changes to see if the viral replication is increasing or decreasing and watch the trend, which is a quantitative. In addition, there may also refer to the quantification of the five items of hepatitis B. For each of the five items of hepatitis B, there is a quantification value, and through this quantification, we can determine whether it is negative or positive, so as to determine whether it is a major or minor triple-positive. The quantification of the hepatitis B virus includes these two main aspects. If the hepatitis B virus has caused damage to the liver, each item in the liver function is also basically quantitative. Items like glutamic aminotransferase and glutamic oxalacetic aminotransferase are not qualitative, but quantitative tests with specific values.
