Hepatitis B e Antigen Test (HBeAg - quant)
Track active viral replication and treatment response with precision.
The Hepatitis B e Antigen Test (HBeAg - quant) is a quantitative blood test used to measure the level of hepatitis B e antigen in the bloodstream. It is primarily requested for individuals known to be hepatitis B surface antigen (HBsAg) positive, to assess the level of viral replication and infectivity. This test is also valuable for monitoring response to antiviral therapy in chronic hepatitis B patients, helping clinicians determine whether treatment is effectively suppressing viral activity. The test uses a quantitative immunoassay method to provide an exact measurement of HBeAg concentration, offering more detailed information than a simple positive or negative result.
Biomarkers Included
- Hepatitis B e antigen (HBeAg - quant): A viral protein produced during active hepatitis B replication. Quantifying its level helps gauge the intensity of viral activity and the likelihood of transmission.
Why it matters
Knowing the exact quantity of HBeAg gives clinicians a clearer picture of how actively the hepatitis B virus is replicating. This supports informed decisions about starting or adjusting antiviral treatment, and it helps track whether the virus is being successfully suppressed over time. For patients, it means more precise monitoring and a better understanding of their infection status.

No special preparation required.
For blood tests, we recommend drinking plenty of water beforehand to ensure smooth sample collection. If you are taking any regular medication, continue to do so unless advised otherwise by your doctor.
Important Clinical Information:
This test is a screening tool to monitor and support your overall health. It does not replace your GP or Consultant.
Always discuss your test results, especially any abnormal results, with your GP, who can interpret them in the context of your medical history and overall health.
