What this test is
The hepatitis B immunity status test measures antibodies in your blood that indicate protection against the hepatitis B virus. It typically detects IgG and IgM antibodies, which are produced by the immune system in response to vaccination or infection. This test does not diagnose an active infection but rather assesses your immune status.
What it measures
- Hepatitis B surface antibody (anti-HBs) — indicates immunity from vaccination or past infection
- Hepatitis B core antibody (anti-HBc) — can indicate past or ongoing infection
- IgG antibody — a type of antibody that may suggest longer-term immunity
- IgM antibody — a type of antibody that may suggest recent infection
What the test involves
A healthcare professional collects a small sample of blood from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test to determine if you are protected against hepatitis B, especially if you are at risk of exposure or need proof of immunity for work, school, or travel. It can also be used to check if a vaccination series was effective.
Preparation
No special preparation is usually needed for this blood test. However, always follow the specific instructions provided by the lab or your healthcare provider.
How results are reported
Results are typically reported as positive or negative for the antibodies, sometimes with a numerical value. Reference ranges can vary between laboratories, so your results should be interpreted in the context of the lab's own ranges.
