Anti-HBs (Hepatitis B Immunity)

An Anti-HBs test professionally and confidentially verifies your hepatitis B immunity status. Our laboratory delivers reliable, discreet results so you can confirm your protection against hepatitis B with complete peace of mind.

What It Measures

This test detects the presence of antibodies directed against the hepatitis B surface antigen (HBsAg). These protective antibodies are produced by the immune system following vaccination or recovery from a hepatitis B infection. The test provides a qualitative result indicating whether sufficient antibodies are present for immunity.

Why It Matters

Hepatitis B can lead to chronic liver disease if not managed appropriately. Verifying your Anti-HBs status helps confirm whether you are protected against the virus. This is important for healthcare workers, individuals with potential exposure, and anyone wanting to confirm their vaccination response. Consult a healthcare professional for interpretation.

When to Test

Testing may be recommended after completing a hepatitis B vaccination series to verify immunity, for healthcare workers and others at occupational risk, or if you have been exposed to someone with hepatitis B. Consult a healthcare professional for guidance.

Lifestyle Tips

Ensure your hepatitis B vaccination is up to date. Practise safe hygiene when handling blood or bodily fluids. If you are a healthcare worker or at increased risk, discuss regular antibody monitoring with your healthcare provider. Avoid sharing personal items such as razors or toothbrushes.

Frequently Asked Questions

What does it mean if my Anti-HBs test is negative?
A negative result may indicate that you are not immune to hepatitis B. This could mean you have not been vaccinated, or that your vaccination did not produce a sufficient immune response. Your healthcare professional may recommend vaccination or a booster dose.
How long does hepatitis B vaccine immunity last?
For most people, the hepatitis B vaccine provides long-lasting protection, often for decades or even a lifetime. However, in some individuals, antibody levels may decrease over time. Regular testing can help monitor your immunity status. Consult your healthcare provider for personalised advice.
