Hepatitis B DNA quantification of less than 100 may be due to the fact that the Hepatitis B virus is not in the replication phase or replication is not active in the body, suggesting low infectiousness. Hepatitis B Deoxyribonucleic Acid, also known as Hepatitis B Virus DNA, is an indicator of active replication of the Hepatitis B Virus and the infectiousness of the Hepatitis B Virus. Due to the different sensitivity of different test kits, the normal range is also different. The normal range is usually less than 100 (some kits are less than 20). If Hepatitis B DNA is less than 100, it usually indicates that the Hepatitis B virus is not in an active state of replication, which may be due to the suppression of viral replication by antiviral therapy, or that the virus itself is not actively replicating. This is a good indication that the organism is less infectious.
