Hepatitis B Virus Replication Number is mainly judged high or low based on the normal value indicated on the back of the test, which is usually below 1000 IU/ml for quantitative Hepatitis B test. Hepatitis B virus does not exist in the blood of normal people, and the number of hepatitis B virus replication is detected as negative in the qualitative test, and below the lower of the quantitative test. , while hepatitis B virus carriers, hepatitis B triple positive, hepatitis B triple positive, hepatitis B minor triple positive, hepatitis B minor bi-positive and other conditions, need to carry out the hepatitis B virus DNA test.
