What is the purpose of this test?
The Diphtheria Antitoxoid Blood Test is a crucial diagnostic tool used to evaluate the immune response to diphtheria immunization. It works by measuring the concentration of antibodies in the blood, which helps determine if an individual has developed sufficient immunity against diphtheria, a potentially harmful bacterial infection.
This test is particularly useful in identifying individuals who may be vulnerable to diphtheria and require additional immunization. The test results can also be used to monitor the effectiveness of a previous diphtheria vaccine or to determine if an individual needs a booster shot. It's important to note that antibody levels of ≥0.10 IU/mL are considered protective, indicating an adequate immune response. However, a lower antibody level may suggest that an individual is not adequately protected against the diphtheria infection.
Who would benefit from this test?
The Diphtheria Antitoxoid Blood Test would be beneficial to:
- Individuals recently vaccinated against diphtheria
