This test is used to look for the presence of Hepatitis B (Hep B) viral genetic material in the blood. The results for this test are quantitative, meaning they provide a numerical result rather than a simple positive or negative. Because Viral DNA is often detectable sooner than antibodies developed in response to an infection, Hep B PCR testing can be used as a screening for people who have had a recent exposure. This test can also be used a confirmatory test for a previous positive result or to assist in monitoring the effects of antiviral therapy.
Hepatitis B is a viral liver infection which is spread through exposure to infected blood or bodily fluids. It is the most common cause of acute viral Hepatitis. Hepatitis B infections often show no symptoms but when symptoms do occur they are often described as flu-like. Common symptoms include abdominal pain, fever, loss of appetite, nausea, joint pain, fatigue, jaundice, and dark colored urine. Chronic Hep B infections can cause serious health complications like Cirrhosis and Liver Cancer.
This test is typically ordered by people:
Results for this test are quantitative. People who require a Hep B PCR test but only desire a positive or negative result may order the Hepatitis B PCR Qualitative test. People who wish to order a Hepatitis B screening but do not require an early exposure test should consider the Hepatitis B surface Antigen test or the Hepatitis B Panel as they are highly accurate at 3-12 weeks or greater after exposure.
Turnaround time for the Hepatitis B PCR Quantitative test is typically 5-7 business days.
Note: Result turn around times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
The Hepatitis B PCR test can typically detect the virus 3 weeks from exposure or any time after. Some people may be detectable earlier.
This Hepatitis B testing does not have any special requirements.
