Quick answer
The HBeAg Test costs ₹700 at Live Line Health Care. Checks for the hepatitis B e antigen in people with hepatitis B. No fasting is needed. It uses a blood sample and the report is usually ready within 24 hours. Book home sample collection or visit any of our 45 centres.
Also known as: Hepatitis B e Antigen, HBe Antigen, Hepatitis B Envelope Antigen, HBeAg ELISA, Hepatitis Be Antigen
What is the HBeAg Test?
The HBeAg test looks for the hepatitis B e antigen, a protein made while the hepatitis B virus is actively copying itself in liver cells. It is not a screening test for hepatitis B. It is usually ordered for people already known to be HBsAg positive, to understand how active their infection is. A reactive HBeAg generally means high levels of virus in the blood and greater infectivity, meaning the virus spreads more easily to partners, household members and, in pregnancy, to the baby.
Over time, many people lose HBeAg and develop its antibody, anti-HBe. This change, called seroconversion, often signals that the virus has quietened down. The picture is not always so simple. Some strains common in Asia make little or no e antigen, so a person can be HBeAg non-reactive yet still have active disease. That is why doctors combine this result with HBV DNA, liver enzymes and scans. For the full set of markers in one report, including immunity from vaccination, the Hepatitis B Profile is the broader test.
What it measures: The hepatitis B e antigen in blood, a marker of active viral replication.
Parameters included (1)
- Hepatitis B e Antigen: Reactive or Non-reactive
Why is this test done?
- Assessing a person newly found to be HBsAg positive
- Pregnancy in a woman with hepatitis B, to judge the risk of passing it to the baby
- Monitoring chronic hepatitis B over time
- Checking for e antigen loss during or after antiviral treatment
When should you get tested?
- Usually none, as chronic hepatitis B is often silent
- Tiredness or poor appetite
- Jaundice during a flare of liver inflammation
- Raised SGPT (ALT) on a liver function test
How to prepare for the HBeAg Test
- 1Fasting is not required for HBeAg.
- 2Carry your HBsAg report and any HBV DNA or liver function results.
- 3If you are pregnant, mention how many weeks along you are.
- 4Keep taking any prescribed hepatitis B medicine as usual unless your doctor tells you otherwise.
HBeAg Test normal range
| Parameter | Typical reference range |
|---|---|
| Non-reactive | HBeAg not detected |
| Reactive | HBeAg detected, which usually means active viral replication and higher infectivity |
Results may also show an index with a cut-off. A non-reactive result does not by itself mean the infection is inactive. Ranges are typical adult values and vary between labs, age and sex. Always use the range printed on your report and discuss results with your doctor.
Understanding your results
- A reactive result in someone with hepatitis B usually reflects high virus levels. Your doctor will check HBV DNA and liver enzymes to decide on monitoring or treatment.
- Moving from HBeAg reactive to non-reactive with anti-HBe appearing is often a favourable change.
- Some people are HBeAg non-reactive but still have significant virus levels, so HBV DNA remains the key test.
- Babies of mothers with hepatitis B should receive hepatitis B vaccine and immunoglobulin soon after birth. Discuss the plan with your obstetrician well before delivery.
- Partners and family members should be tested and vaccinated if they are not already immune.
HBeAg Test – FAQs
What is the price of the HBeAg Test?
The HBeAg Test costs ₹700 at Live Line Health Care, at all 45 centres and for home sample collection.
What does HBeAg positive mean?
It means the hepatitis B virus is actively multiplying, and blood levels of the virus are usually high. The infection is then more easily passed to others. It is not a diagnosis of liver damage, so your doctor will check liver tests and HBV DNA.
Is HBeAg negative a good result?
Often it is, especially when anti-HBe is reactive, which suggests the virus has calmed down. However, some virus strains do not make e antigen, so HBV DNA is still needed to confirm that the infection is truly inactive.
Why is HBeAg tested during pregnancy?
Mothers who are HBeAg reactive have a higher chance of passing hepatitis B to their baby. The result, along with HBV DNA, helps doctors plan care, which may include antiviral medicine late in pregnancy and protection for the baby at birth.
What is the difference between HBsAg and HBeAg?
HBsAg shows that hepatitis B infection is present. HBeAg shows how active it is. HBsAg is used for screening, while HBeAg is tested in people already known to have hepatitis B, to judge virus activity and infectivity.
Can HBeAg become negative on its own?
Yes. Many people lose HBeAg naturally over years as their immune system controls the virus, often with a temporary rise in liver enzymes. Antiviral treatment can also help. Regular follow-up shows when this change happens.
Where can I get the HBeAg Test done?
At any of our 45 Live Line Health Care centres in 40 cities across Andhra Pradesh and Telangana, including Hyderabad, Visakhapatnam, Warangal, Kakinada and Nellore, or book home sample collection.
