Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
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.
Reference Ranges
Reference ranges may vary between laboratories. When you order a test, a BIG-registered doctor assesses your personal results in context. For treatment decisions, discuss your results with your GP.
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.
