FAQ
Frequently asked questions
Why is tetanus and diphtheria immunity important?
Tetanus is a serious bacterial illness that affects the nervous system, causing painful muscle stiffness and spasms. Diphtheria is a contagious bacterial disease that can lead to breathing difficulties, heart problems, and even death. Maintaining immunity through vaccination is crucial for preventing these potentially severe illnesses.
How often should I get tested for tetanus and diphtheria immunity?
The need for repeat testing or booster shots depends on your vaccination history and the recommendations of your healthcare provider. Generally, tetanus and diphtheria boosters are recommended every 10 years.
What does a positive or negative result mean?
A positive result generally indicates that you have sufficient antibodies to be protected against tetanus and/or diphtheria. A negative or low result may suggest that your immunity has waned and a booster vaccination might be recommended.
Can this test be done if I haven't been vaccinated?
This test is primarily used to assess immunity in individuals who have previously been vaccinated. If you have never been vaccinated, the test may show no detectable antibodies, and your clinician will likely recommend a primary vaccination series.
