What's this test for?

This test is ideal if you need to verify your immunity against diphtheria and tetanus, whether for travel requirements, school or work clearance, or simply peace of mind. It's especially useful if you're unsure about your vaccination history, haven't had a booster in many years, or were exposed to a potential infection through a wound or cut. Many people use this test to confirm they're protected without needing unnecessary booster shots.

What's included in this test?

Diphtheria Antitoxoid Tetanus Antitoxoid

This test measures antibody levels for both diphtheria and tetanus to determine if you have adequate immunity against these potentially life-threatening bacterial infections. Diphtheria antibodies indicate protection against a disease that can cause severe breathing problems and heart failure, while tetanus antibodies show immunity to the bacteria that causes dangerous muscle spasms and lockjaw. Together, these measurements tell you whether your body has enough protection or if you need a booster vaccination.

What happens after I get my results?

You'll receive detailed doctor notes in simple language explaining whether your immunity levels are adequate or if you need a booster vaccination. These notes include personalized recommendations on when to get your next booster, what to do if immunity is low, and how to maintain protection. You'll also get the standard lab report and can track your immunity levels over time using our trends feature, which is especially helpful for monitoring protection as immunity can wane over the years.

When will I get my results?
Most immunity test results are typically available within 3-5 business days after your sample reaches the lab. You'll receive an email notification as soon as your results are ready to view. Complex antibody tests may occasionally take slightly longer, but we'll keep you informed throughout the process.
Who should consider getting this test?
This test is ideal for anyone who cannot locate their vaccination records, adults who haven't had a booster in 10+ years, healthcare workers who need proof of immunity, or people planning international travel to areas where these diseases are more common. It's also important for older adults, people with compromised immune systems, or anyone who sustained a deep wound or puncture injury and wants to confirm they're protected against tetanus.
What symptoms indicate I may need this test?
While this test is primarily preventive, you should consider it urgently if you've had a deep cut, puncture wound, or injury exposed to dirt or rust and you're unsure of your tetanus immunity status. If you've been exposed to someone with diphtheria or have traveled to an area with an outbreak, testing can help determine if you need immediate medical attention. Most people get this test proactively before symptoms occur to ensure they're protected.
How can I maintain my immunity against diphtheria and tetanus?
The most effective way to maintain immunity is to stay current with your booster vaccinations, typically recommended every 10 years for adults. Keeping a personal health record of all your vaccinations helps you track when boosters are due. A healthy immune system through proper nutrition, adequate sleep, regular exercise, and stress management also helps your body maintain better antibody responses to vaccines.
What is tetanus and why does it matter?
Tetanus is a serious bacterial infection caused by Clostridium tetani, often entering the body through cuts, puncture wounds, or injuries contaminated with soil or rust. It causes painful muscle contractions and spasms, particularly in the jaw (lockjaw) and neck, and can be life-threatening if untreated. The bacteria produce a toxin that affects your nervous system, which is why maintaining immunity through vaccination is crucial since tetanus cannot be spread person-to-person but exists commonly in the environment.
What does low immunity to diphtheria or tetanus mean?
Low antibody levels mean your body doesn't have enough protective antibodies to fight off these infections if you're exposed. This typically happens when you haven't been vaccinated, your last booster was more than 10-15 years ago, or your immune system didn't respond adequately to previous vaccinations. If your results show low immunity, you'll need a booster shot to restore protection.
How often should I retest my immunity levels?
For most adults with adequate immunity, retesting isn't necessary if you're keeping up with recommended booster shots every 10 years. However, if your test shows borderline or low immunity after getting a booster, retesting in 4-6 weeks can confirm your immune system responded properly. Healthcare workers or people in high-risk occupations may need to verify immunity every 5-10 years depending on their employer's requirements.

What this means

Your tetanus antibody levels are below the protective threshold, meaning you may not have sufficient immunity if exposed to tetanus bacteria. This typically happens when your last vaccination or booster was more than 10-15 years ago, or if you've never been fully vaccinated. Getting a tetanus booster will quickly restore your protection.

* Regular blood test results (e.g., CBC) typically start arriving the next business day after sample collection. More complex tests, such as hormone panels, may take up to 10–15 business days due to their complexity.
