Is it necessary to perform highly sensitive HBV DNA testing?

Generally, highly sensitive HBV DNA quantitative analysis is not required for all patients with hepatitis B virus (HBV). High-sensitivity testing is particularly important for patients with low levels of HBV undergoing antiviral therapy.

Highly sensitive HBV DNA testing refers to detecting the amount of HBV DNA in the body after infection with the hepatitis B virus. When HBV DNA levels exceed the normal range, it indicates a higher degree of infection and suggests the need for timely treatment. Highly sensitive HBV DNA testing is recommended when a patient's hepatitis B DNA level is below 100 IU/mL or when the patient is considering discontinuation of medication. This high-sensitivity test allows for more precise measurement of viral load. Quantitative nucleic acid testing for hepatitis B virus helps doctors understand the amount of HBV present in the body and assess whether the virus is actively replicating. Higher HBV DNA levels often indicate increased hepatitis activity, stronger infectivity, and worsening liver damage. Therefore, regular monitoring of HBV DNA is essential, especially during treatment.

Hence, integrating multiple testing indicators for comprehensive analysis of hepatitis B infection enables a more thorough understanding of the disease status and facilitates the selection of more appropriate treatment strategies.
