The Tetanus & Diphtheria Titer Test test contains 1 test with 2 biomarkers.

Brief Description: The Tetanus & Diphtheria Titer Test is a blood test that measures the concentration of antibodies against tetanus (lockjaw) and diphtheria, both of which are serious bacterial infections. The presence and level of these antibodies indicate whether an individual has immunity to these diseases, either from previous infections, vaccinations, or a combination of both. The test specifically quantifies the immune response to the toxins produced by these bacteria, rather than to the bacteria themselves.

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

When and Why a Tetanus & Diphtheria Titer Test May Be Ordered

This test may be ordered for several reasons:

  1. Pre-Employment Screening for Healthcare Workers: To ensure immunity and protect vulnerable populations.
  2. After Potential Exposure to Tetanus or Diphtheria: Especially if the individual's vaccination status is unknown or if they are at high risk.
  3. To Verify Immunity: In individuals who are unsure of their vaccination history or when documentation is unavailable.
  4. Before Travel: For people traveling to areas where these diseases are more common.
  5. During Pregnancy: To ensure the mother has immunity, which can be passed on to the newborn.

What the Tetanus & Diphtheria Titer Test Checks For

The test checks for the presence of antibodies to tetanus and diphtheria toxins in the blood. High levels of antibodies indicate that an individual has either been vaccinated against these diseases or has had them in the past and developed immunity. It does not detect current infections but measures immunity levels against these potentially fatal diseases.

Additional Lab Tests Ordered Alongside a Tetanus & Diphtheria Titer Test

How Health Care Providers Use the Results of a Tetanus & Diphtheria Titer Test

Healthcare providers use the results of the Tetanus & Diphtheria Titer Test to:

  1. Determine Immunity: To confirm if an individual has sufficient immunity to tetanus and diphtheria and whether booster vaccinations are needed.
  2. Guide Vaccination Schedules: The results can inform whether additional doses of the tetanus-diphtheria vaccine or the Tdap (tetanus, diphtheria, and pertussis) vaccine are required, particularly in adults or healthcare workers.
  3. Assess Need for Post-Exposure Prophylaxis: In the event of a suspected exposure to tetanus, the test can help decide if treatment with tetanus immunoglobulin is necessary.
  4. Occupational Health Decisions: In healthcare and other settings where exposure to these diseases is more likely, titer results can be used to ensure workforce safety and compliance with health regulations.
  5. Public Health Monitoring: In broader epidemiological contexts, these tests help monitor the immunity levels within populations, guiding public health vaccination strategies.
We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
