What This Test Measures
This test measures IgG antibodies to Bordetella pertussis, the bacteria that causes whooping cough. It looks specifically at B pertussis IgG Ab, an IgG antibody your immune system may produce in response to past vaccination or prior infection.
This is an IgG-only test. A result showing these antibodies can help indicate prior exposure to Bordetella pertussis through vaccination or infection, but it does not on its own provide a complete picture of your immune status or confirm a specific diagnosis.
Benefits
- Checks for IgG antibodies related to Bordetella pertussis exposure
- Helps confirm prior vaccination or infection status
- Useful for meeting workplace or school immunity documentation requests
- Simple blood draw with no special preparation required
- Results available in a short turnaround window
Who Is This Test For?
- Individuals asked to provide proof of pertussis immunity for work
- Students needing immunization documentation for school enrollment
- Adults wanting to check their Bordetella pertussis antibody status
- People unsure whether they still have immunity from past vaccination
- Individuals advised by a healthcare provider to check antibody status

FAQ
1. What is the purpose of this test?
This test measures IgG antibodies to Bordetella pertussis (B. pertussis IgG Ab). It may help a healthcare provider evaluate whether you have antibodies related to prior vaccination or past infection with the bacteria that causes whooping cough. This test 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 documentation of your antibody status for a workplace or institution, want to review prior vaccination or infection status, or are discussing your Bordetella pertussis antibody status with your healthcare provider.
3. Does this test measure other antibody types?
No. This test measures B. pertussis IgG antibodies only. It does not measure IgA, IgM, IgE, IgD, total IgG, or IgG subclasses. Each antibody class provides different information, so this test cannot replace testing for another antibody type.
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 1–4 business days. Weather, holidays, or laboratory delays may extend this timeframe.
6. How do I interpret the results?
The meaning of your IgG result depends on the specific antibody target and your individual clinical context. Your healthcare provider may consider your vaccination history, prior symptoms, exposure history, and timing when reviewing the result. A positive result does not automatically confirm active infection, immunity, or protection, and a negative result does not rule out a condition. This result reflects IgG status only.
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 result is outside the expected range?
Review your result with a qualified healthcare provider. They can explain what it may mean in the context of your health history and determine whether additional evaluation or testing is appropriate.
8. How often should I get tested?
There is no set testing schedule. Follow your healthcare provider’s guidance based on your individual needs.
