Qualitative HBV PCR looks for hepatitis B viral DNA in the submitted blood sample. It reports detection rather than the amount of virus.

Understanding the test
Also called Hepatitis B Viral DNA
A clinician may request qualitative HBV DNA after other hepatitis B markers are detected or unclear. Previous antigen, antibody and treatment information helps explain the request.
Qualitative HBV PCR can help assess hepatitis B activity when read with the serology and liver tests.
A specialist chooses a quantitative viral-load test when monitoring the amount of HBV DNA over time.
Before your sample
No fast is needed. Bring hepatitis B antigen, antibody and prior DNA findings and tell the clinician about antiviral treatment. Continue treatment as prescribed.
The clinician takes blood from a vein into a tube that keeps it from clotting. The collection team sends the labelled specimen to the laboratory.

Detection establishes the presence of DNA in that specimen. An undetectable qualitative result does not by itself rule out hepatitis B in all clinical circumstances.

Patient questions
No. A quantitative test measures an amount. This qualitative test asks whether DNA is detectable and must be read with the other hepatitis B markers.
Because hepatitis B that has been quiet can reactivate when the immune system is suppressed, for example by chemotherapy. Checking for viral DNA, together with the antigen and antibody tests, helps your doctor decide whether you need protective antiviral treatment or closer monitoring during the course, rather than discovering a flare once it has begun.
No. HBV PCR shows whether the virus is present and replicating, but it says nothing about how much damage the liver has sustained. That needs liver blood tests, imaging or other assessment of scarring. Someone with detectable virus can have a healthy liver, and the reverse can also be true, which is why the tests are read together.
