The Anti HBs Titre (HBsAb) Test is a blood test that detects antibodies against the Hepatitis B surface antigen (HBsAg). It helps determine if a person is immune to Hepatitis B — either from vaccination or recovery after infection. This test is especially important for healthcare professionals, pregnant women, and individuals who have completed the Hepatitis B vaccination series. At Diagnopein, we offer accurate and fast testing to help you understand your Hepatitis B immunity status with ease.
Why Is the Anti HBs Titre Test Important?
When Should You Get Tested?
Doctors may recommend the Anti HBs (HBsAb) test in the following situations:
Understanding the Test Results
| Result | Interpretation |
|---|---|
| <10 mIU/mL | Not immune – Vaccination or booster needed |
| ≥10 mIU/mL | Immune – Sufficient antibody levels |
| High levels | May indicate recent vaccination or past infection recovery |
Your doctor will interpret the results in context with your medical history and other Hepatitis B markers like HBsAg and Anti-HBc.

At Diagnopein, we strive to provide timely results, typically within a few days. The exact timeframe may vary based on the specific test and laboratory workload.
An Anti-HBs level greater than 500 indicates strong immunity to the Hepatitis B virus, suggesting a robust response to vaccination or previous infection.
Yes, the Anti-HBs test is safe. There may be slight discomfort during the blood draw, but serious complications are rare.
Positive Result: The presence of Anti-HBs indicates immunity to Hepatitis B, meaning you have either been vaccinated or have recovered from an infection. Negative Result: No Anti-HBs detected may indicate that you have not been vaccinated or have not been infected with Hepatitis B.
The test is performed by drawing a blood sample from a vein in your arm. The sample is then analyzed in a laboratory to check for the presence of Hepatitis B surface antibodies.
The Anti-HBs (HBsAb) test is primarily used to determine whether a person has developed immunity to the Hepatitis B virus, either through vaccination or recovery from a past infection. It helps in assessing the effectiveness of the Hepatitis B vaccine and in evaluating an individual's overall immune status against the virus.
If your Anti-HBs level exceeds 1000, it indicates an even higher level of immunity, suggesting an excellent immune response. This level is particularly important for individuals at risk of Hepatitis B exposure.
Anti-HBs indicates immunity to Hepatitis B, while Anti-HBc (Hepatitis B core antibody) indicates a past or current infection with the virus. A person can have both antibodies, which means they have recovered from an infection and developed immunity.
