Immunity detection and titer testing is a blood test that checks whether you have antibodies against specific infections or vaccines. It helps determine if you are protected or need a booster, often for school, work, or travel requirements.

What it measures

  • Antibody levels (titers) — Measures the amount of antibodies against a specific disease, such as measles or hepatitis B.
  • Immune status (positive/negative) — Indicates whether you likely have protection based on a threshold set by the lab.
  • IgG antibodies — Shows past infection or vaccination, as these antibodies develop over time.
  • IgM antibodies — Suggests a recent or current infection, but is not always included.

Who it is for

This test is often ordered by employers, schools, or travel clinics to verify immunity. A healthcare provider may also order it if you are unsure about your vaccination history.

Preparation

No fasting is required. Tell your provider about any medications or conditions that affect your immune system.

Results and what they mean

Results are reported as positive or negative, or as a number with a reference range. A clinician interprets these results in the context of your health and vaccination history. This is general information, not medical advice.
