Quick Facts
- Sample: Blood
- Fasting: No special preparation is required
- Turnaround: 2-6 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 detects Diphtheria Antitoxoid Ab and Tetanus Antitoxoid IgG Ab in your blood. It helps a healthcare provider evaluate whether you have developed immunity to diphtheria and tetanus through vaccination or prior infection. It does not diagnose active infection with either disease on its own.
2. Who would benefit from this test?
This test may benefit individuals who need to confirm their immunization status, such as those required by an employer or institution to provide proof of tetanus and diphtheria immunity. It may also help individuals who are uncertain about their vaccination history.
3. When should I order this test?
You may consider ordering this test if you need to provide documentation of tetanus and diphtheria immunity for work or school. It may also be useful if you are unsure whether you are still protected and want to discuss booster options with your provider.
4. What does this test measure?
This test measures two antibodies from a blood sample: Diphtheria Antitoxoid Ab and Tetanus Antitoxoid IgG Ab. These are antibody titers that reflect your immune response to each disease, rather than a direct test for active infection. The two antibodies are reported separately and reflect immunity to diphtheria and tetanus individually.
5. Do I need to fast before this test?
No special preparation is required for this test.
6. How quickly will I get results?
Results are typically available in 2-6 days. Results may take longer based on weather, holiday, or lab delays.
7. How do I interpret the results?
The meaning of your antibody levels depends on your vaccination history, medical history, and other individual factors. An antibody level outside the expected range does not automatically confirm a lack of immunity, and a level within the expected range does not automatically rule out the need for a booster. Because this test reports two separate antibodies, each result should be considered individually rather than combined into a single conclusion. Discuss your results with a qualified healthcare provider for personalized interpretation.
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.
8. What should I do if my results are abnormal?
If either antibody result falls outside the expected range, review your results with a qualified healthcare provider. They can help you understand what the result means for your immunity and whether additional evaluation or a booster vaccination may be appropriate.
9. How often should I get tested?
Testing frequency should be determined as directed by your healthcare provider, based on your individual immunization history and any documentation requirements you may have.
