Hepatitis B Virus PCR Test

What is the Hepatitis B Virus PCR Test?

Hepatitis B Virus PCR Test test is a molecular blood test that detects and measures the genetic material (DNA) of the hepatitis B virus (HBV) using polymerase chain reaction (PCR) technology.

It identifies the presence of HBV DNA in the blood, indicating an active infection.

The test can be qualitative (detecting presence or absence of the virus) or quantitative (measuring the viral load to indicate the amount of virus in the bloodstream).

This test helps diagnose acute or chronic HBV infection, monitor the infection status, and assess response to antiviral treatment.

Indications of the Hepatitis B Virus PCR Test

You may be advised to take this test if you:

• Have tested positive for hepatitis B surface antigen (HBsAg) and need confirmation of active infection

• Are diagnosed with HBV and require monitoring of viral load during treatment

• Show signs or symptoms of liver disease, such as jaundice, fatigue, or abdominal pain

• Have had recent exposure to HBV through blood, sexual contact, or needle sharing

• Are in a high-risk group for HBV infection (e.g., healthcare workers, people who inject drugs)

• Need early detection of HBV, especially in cases where serologic markers are inconclusive

Patient Preparation/Instructions

• No special preparation or fasting is required before the test

• Continue your medications unless instructed otherwise by your healthcare provider

• Blood is drawn from a vein, usually in the arm, for analysis

Typical Reference Values

• Negative (Not Detected): No HBV DNA found, indicating no active infection or viral load below detection limit

• Positive (Detected): HBV DNA present, confirming active infection

• Quantitative results: Viral load is reported as international units per milliliter (IU/mL), which helps to assess infection severity and guide treatment decisions. Viral loads vary widely; very low levels suggest minimal viral activity, while high levels (up to billions IU/mL) indicate active replication and higher transmission risk.

The time it takes to get the Report

Results are typically available within 1 to 7 days, depending on the laboratory and whether the test is qualitative or quantitative.
