Frequently Asked Questions
What does the HBV Genotyping + Viral Load test measure?
It quantifies the amount of Hepatitis B virus DNA in your blood (viral load) and identifies the specific HBV genotype or subtype present, which guides treatment decisions and predicts response to antiviral therapy.
Why is HBV genotyping clinically important?
Different HBV genotypes respond differently to interferon-based and nucleos(t)ide analog therapies. Genotype information helps physicians personalize treatment and predict the likelihood of sustained virological response.
Is fasting required for this test?
No, fasting is not required for HBV genotyping and viral load testing. The sample can be collected at any time of day.
What sample is used for this test?
The test requires EDTA plasma (3 mL) collected in a lavender-top tube. Whole blood in EDTA is also accepted and processed to obtain plasma.
How are viral load results interpreted?
Results are reported in IU/mL. Higher viral loads indicate active viral replication. Treatment decisions are based on viral load thresholds combined with liver enzyme levels and clinical assessment by your physician.
How long does it take to get results?
Verified reports are available within 48–72 hours via www.drpatholab.in or WhatsApp/Email.
