Quick Facts
- Sample: Blood
- Fasting: No special preparation is required
- Turnaround: 2-6 business days (may take longer based on weather, holiday, or lab delays)
What This Test Measures
This test measures two distinct antibodies in your blood: Diphtheria Antitoxoid Ab and Tetanus Antitoxoid IgG Ab. These antibodies are produced by your immune system in response to vaccination against, or prior infection with, Corynebacterium diphtheriae or Clostridium tetani.
The presence and level of these antibodies help indicate whether you have developed immunity to diphtheria and tetanus, either through vaccination or past exposure. This test does not evaluate any other biomarkers, infections, or immune targets beyond these two specific antitoxoid antibodies.
Benefits
- Checks for antibodies related to tetanus immunity
- Checks for antibodies related to diphtheria immunity
- Helps confirm prior vaccination or exposure status
- Supports documentation requests from employers or schools
- Simple blood draw with no special preparation
Who Is This Test For?
- Individuals asked to provide proof of tetanus and diphtheria immunization
- Workers whose employers require immunity documentation
- Students whose institutions require immunization records
- Individuals uncertain about their vaccination history
- Individuals who want to check antibody status before a booster decision

FAQ
1. What is the purpose of this test?
This test measures Diphtheria Antitoxoid Ab and Tetanus Antitoxoid IgG Ab in your blood. It may help a healthcare provider evaluate immunity to diphtheria and tetanus from vaccination or prior infection. It does not diagnose an active infection on its own.
2. When might I consider ordering this test?
You may consider this test if you need proof of tetanus and diphtheria immunity for work or school, are uncertain about your vaccination history, or want to discuss booster options with your healthcare provider.
3. What does this test measure?
This test measures two antibody titers from a blood sample: Diphtheria Antitoxoid Ab and Tetanus Antitoxoid IgG Ab. The results are reported separately and reflect immune response to diphtheria and tetanus individually, rather than testing for an active infection.
4. Do I need to fast or prepare before this test?
No special preparation is required.
5. How quickly will I get results?
Results are typically available in 2–6 business days. Weather, holidays, or laboratory delays may extend this timeframe.
6. How do I interpret the results?
The meaning of each antibody level depends on your vaccination history, medical history, and other individual factors. A result outside the expected range does not automatically confirm a lack of immunity, and a result within the expected range does not automatically rule out the need for a booster. Each antibody result should be considered individually.
Disclaimer: Reference ranges may vary by laboratory. Listed ranges are general guidelines and may differ from those used by the performing lab. Always consult your healthcare provider for interpretation.
7. What should I do if a result is outside the expected range?
Review your results with a qualified healthcare provider. They can explain what they may mean for your immunity and determine whether additional evaluation or a booster vaccination is appropriate.
8. How often should I get tested?
Testing frequency depends on your immunization history and any documentation requirements. Follow your healthcare provider’s guidance on whether repeat testing is appropriate.
