About HBV DNA by PCR (Qualitative)
This PCR test detects whether hepatitis B virus DNA is present in your blood, confirming active viral replication with high sensitivity, useful when other markers give an unclear picture.
No fasting is required, and given the specialised molecular processing involved, results take up to 7 days.
How to Prepare
- No fasting required.
- No special preparation needed before your blood draw.
Frequently Asked Questions
What does this qualitative PCR test check?
It detects whether hepatitis B virus DNA is present in your blood, confirming active viral replication.
Do I need to fast before this test?
No fasting is required.
Why does this test take longer than antigen tests?
Molecular PCR testing involves specialised processing for high sensitivity, which takes more time than standard antigen or antibody tests.
When is this test ordered?
It is typically ordered when other hepatitis B markers give an unclear picture and confirmation of active viral presence is needed.
How soon will my report be ready?
Up to 7 days, given the specialised molecular processing involved.
Is home sample collection available?
Yes, in all City Care Lab service areas.
