Anti-HBs (Hepatitis B Immunity)
An Anti-HBs test is part of a comprehensive health screening that confirms your immunity to hepatitis B. Whether from vaccination or past exposure, knowing your antibody status gives you a complete picture of your immune protection as part of preventive care.
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.
