The tetanus antitoxoid titer test measures the level of antibodies your body has against tetanus, a serious bacterial infection. It is often ordered to check whether you still have protection from a previous tetanus vaccination or to guide booster decisions.
What it measures
- Tetanus antitoxoid antibodies — The amount of protective proteins your immune system made after vaccination or infection.
- Antibody level (titer) — A number that shows how much antibody is in your blood; higher levels generally mean more protection.
- Protective threshold — A cutoff value used to indicate whether you likely have enough antibodies to prevent tetanus.
Who it is for
This test is typically ordered by a clinician for people who need to confirm their tetanus immunity, such as before certain medical procedures, for travel, or when vaccination history is unclear.
Preparation
No fasting or special preparation is required. You can eat and drink normally before the blood draw.
Results and what they mean
Results are reported as a numeric antibody level, often with a note about whether it is above or below a protective threshold. Your clinician interprets the result along with your vaccination history and health status. This is general information only and not medical advice; discuss your results with a qualified healthcare professional.
