What's Included
Tetanus
- Tetanus Antitoxoid IgG Ab: Measures antibodies related to tetanus, an infection caused by Clostridium tetani bacteria found in soil, dust, and manure.
Diphtheria
- Diphtheria Antitoxoid Ab: Measures antibodies related to diphtheria, a contagious infection caused by Corynebacterium diphtheriae that usually affects the nose and throat.
Pertussis

FAQ
1. What is the purpose of this test?
This panel measures antibodies for tetanus, diphtheria, and pertussis in one blood draw. Each biomarker reflects your body's antibody response to a specific bacteria, whether from vaccination or past infection. Together, these three results give a combined picture of your immunity status across all three diseases. This panel does not diagnose any condition on its own.
2. Who would benefit from this test?
This panel is well suited to individuals who need documented proof of immunity to tetanus, diphtheria, and pertussis, such as for employment or school requirements. It also benefits anyone wanting to confirm their antibody status following a past vaccination series. This test does not diagnose illness or predict future infection risk.
3. When should I order this panel?
You might consider ordering this panel if an employer, school, or institution requests proof of TDap immunity, or if you simply want to check your antibody status. It can also be useful if you're uncertain whether a past vaccination produced a lasting antibody response. This panel is not intended to diagnose disease.
4. Do I need to fast before this test?
No special preparation is required for this test.
5. How quickly will I get results?
Results are typically available in 2-5 days, though timing may take longer based on weather, holidays, or lab delays.
6. How do I interpret the results?
Antibody levels are best understood by looking at the pattern across all three biomarkers rather than any single result on its own. A healthcare provider can help you understand what your specific levels mean for your immunity status. This panel does not provide a diagnosis on its own.
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 my results are abnormal?
If any of your results fall outside the expected range, reach out to your healthcare provider to discuss what the results mean and whether further steps, such as a booster vaccine, are appropriate for you.
8. How often should I get tested?
There is no set schedule for this panel. Consider retesting as directed by your healthcare provider, particularly if you need updated proof of immunity or have questions about your antibody status.
9. Why early detection matters
Checking your antibody status can help you and your healthcare provider identify whether your immunity to tetanus, diphtheria, or pertussis may need reinforcement. Staying aware of your antibody levels supports ongoing conversations about your immunization needs over time.
