Hepatitis B dna fluorescence quantification 4.06E+003 (IU/ml) is the existence of hepatitis B virus infection, it is recommended to combine with liver function, hepatitis B markers and other indicators, active treatment. Hepatitis B virus DNA is the ribonucleic acid contained in the hepatitis B virus in the blood, which can accurately reflect how much hepatitis B virus is contained in the blood, so the amount of hepatitis B virus DNA directly reflects the replication level of the virus and the strength of the infectiousness of the patient. The higher the level of hepatitis B DNA, the more viruses in the body, the more active the virus replication, and obviously the more infectious it is. The normal reference value of hepatitis B DNA is less than 500IU/ml, which is considered that HBV-DNA has no replication or very low replication. Therefore Hepatitis B DNA 4.06E+003 (IU/ml) is the presence of Hepatitis B virus infection, which is generally considered to be between 3-5 times the normal reference value, indicating that the virus is replicating slowly at a low level and requires antiviral therapy. Therefore, patients are advised to complete liver function, hepatitis B markers and liver ultrasound to determine the disease and avoid delays.
