Quick answer

The tetanus antitoxoid titer test measures antibodies that protect against tetanus, a serious illness caused by the bacterium Clostridium tetani. It is used to check whether a person has immunity after vaccination, since antibody levels can decline over time. The test uses a blood sample and is interpreted by a qualified healthcare provider.

What this test measures

Tetanus is caused by a toxin produced by Clostridium tetani, a bacterium found in soil and dust. Vaccination with tetanus toxoid prompts the immune system to make antibodies that neutralize the toxin. A titer test measures the amount of these antibodies in the blood to estimate whether protection is present.

The test uses a serum sample collected by a standard blood draw. The laboratory reports an antibody level, often in international units per milliliter, and compares it with a threshold that is generally considered protective. Results near or below the threshold may prompt a discussion about revaccination.

Titer testing is often requested before travel, for certain occupations, or when vaccination records are uncertain. It gives an objective measure of immunity but does not replace clinical judgment, so a healthcare provider decides what action, if any, a result suggests.
