Immunity Detection & Titer Testing in Vermont

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.

Results and what they mean
