Hepatitis B PCR Viral Load Test (HBV DNA)
Know your viral load, guide your hepatitis B care.
The Hepatitis B Viral Load Test is a blood test that measures the amount of hepatitis B virus DNA in your bloodstream. It is used to assess how actively the virus is replicating and to monitor the effectiveness of antiviral treatment. This test is important for people diagnosed with chronic hepatitis B, those considering or undergoing treatment, and individuals who need to understand their infectivity and risk of liver disease progression.
What it measures
- Hepatitis B virus DNA (HBV PCR): The quantity of hepatitis B viral genetic material in the blood, reported as international units per millilitre (IU/mL).
Who it is for
- Individuals with known chronic hepatitis B infection
- Patients starting or currently on antiviral therapy for hepatitis B
- People who need to assess viral replication status and infectivity
- Those monitoring response to treatment or checking for viral relapse
Why it matters
Knowing your hepatitis B viral load helps your doctor make informed decisions about treatment, monitor how well therapy is working, and assess the risk of liver damage. Regular monitoring can detect rising viral levels early, allowing timely adjustments to your care plan.
