The Hepatitis B Immunity Blood Test is a diagnostic test used to determine your immune status against the hepatitis B virus (HBV). This test checks for the presence of antibodies that indicate either past vaccination or recovery from a prior infection, offering insights into your immunity and potential need for further vaccination or protection.

Blood Test Cost – £79

Why Is the Hepatitis B Immunity Test Important?

Hepatitis B is a liver infection caused by the hepatitis B virus, which can lead to chronic liver disease, cirrhosis, or liver cancer if untreated. Knowing your immune status can help:

  • Confirm immunity after vaccination.
  • Determine if additional vaccination is needed.
  • Assess if you’ve been previously exposed to the virus.

Who Should Consider This Test?

You may benefit from this test if you:

  • Have received the hepatitis B vaccine and want to confirm immunity.
  • Work in a healthcare or high-risk environment.
  • Are planning to travel to regions with a high prevalence of hepatitis B.
  • Have been in close contact with someone diagnosed with hepatitis B.
  • Are undergoing evaluation for liver-related symptoms or conditions.

What Does the Test Measure?

The test measures specific markers of hepatitis B immunity:

  1. Hepatitis B Surface Antibodies (anti-HBs):
    • Indicates immunity due to vaccination or recovery from past infection.
  2. Hepatitis B Core Antibodies (anti-HBc):
    • Indicates past or ongoing infection but not vaccination.

How Is the Test Conducted?

  1. Blood Sample Collection:
    • A small sample of blood is taken from a vein in your arm.
  2. Laboratory Analysis:
    • The sample is analyzed to detect the presence of specific antibodies.
  3. Results Interpretation:
    • Positive anti-HBs: Indicates immunity due to prior vaccination or infection recovery.
    • Negative anti-HBs: Suggests no immunity; vaccination may be recommended.
    • Positive anti-HBc: May indicate past infection, requiring further tests to confirm active or resolved status.

Understanding Your Results

  • Immune: Presence of anti-HBs confirms immunity, with no need for further action.
  • Non-Immune: Absence of anti-HBs indicates no immunity; hepatitis B vaccination may be advised.
  • Exposed to HBV: If anti-HBc is positive, further testing may be required to evaluate infection status.

Preparation and Risks

  • Preparation: No special preparation is required for this test.
  • Risks: Minimal risks associated with blood collection, such as slight bruising or discomfort.

Next Steps After Testing

If your results indicate a lack of immunity, your doctor may recommend a hepatitis B vaccination series. If prior exposure is detected, additional testing may be required to monitor your liver health and determine whether further treatment is necessary.
