This test measures IgG antibody levels for both tetanus and diphtheria to verify that your vaccinations are still providing adequate protection. Tetanus boosters are recommended every 10 years, but many adults fall behind. This test is useful for verifying immunity before travel, after injury, or for anyone unsure of their vaccination history.
