Hepatitis B Virus (HBV) DNA Qualitative Test :
A blood test that detects the presence or absence of Hepatitis B virus (HBV) DNA in the blood. This test is used to confirm active infection by identifying whether the virus is replicating. A positive result indicates the presence of the virus, confirming an ongoing infection, while a negative result suggests that there is no detectable viral DNA, meaning either the infection has been cleared or is not present at detectable levels. This test is often used in combination with other markers (e.g., HBsAg, Anti-HBc) to diagnose and monitor Hepatitis B infections.
