Clinical Significance

Tetanus is caused by Clostridium tetani. Immunization with Tetanus Antitoxoid is effective with boosters in immunocompetent individuals. Antibody levels of > or = to 0.10 IU/mL are considered protective. However, tetanus can still occur in some individuals with such antibody levels. These results should not be used to determine the necessity to administer antitoxin when clinically indicated. For Pre and Post vaccination testing to assess normal immune response, please refer to Test Code 91424, Tetanus Antitoxoid, Pre and Post Vaccination.
