Description
Why It’s Done (Purpose):
1. Monitor Disease Progression and Viral Load:
o Helps determine the amount of virus in the blood, which can be an indicator of the severity of the infection and how well the liver is being affected.
2. Evaluate Treatment Effectiveness:
o Used to assess the effectiveness of antiviral therapy in patients with chronic Hepatitis B, guiding treatment decisions and monitoring response to treatment over time.
3. Assess Chronic Hepatitis B Infection:
o For individuals with chronic Hepatitis B, the test helps determine whether the virus is actively replicating and whether treatment is needed.
4. Detect Drug Resistance:
o The test can also be useful in detecting drug-resistant strains of HBV in individuals who are undergoing antiviral therapy.
5. Determine Risk of Liver Damage or Complications:
o Higher viral loads are generally associated with greater liver damage, including cirrhosis or liver cancer (hepatocellular carcinoma).
Preparation Guidelines:
• No special preparation is typically needed for this blood test.
• Fasting is not required.
• A blood sample will be drawn from a vein.
• Inform your healthcare provider about:
o Any current antiviral medications you are taking (especially for Hepatitis B).
o Any other medications, as some might affect the viral load or liver function.
o Any recent symptoms (e.g., fatigue, jaundice, abdominal pain) or changes in liver function.
