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
