Test Code DTABS Diphtheria/Tetanus Antibody Panel, Serum
Useful For
Assessing antibody response to tetanus and diphtheria toxoid vaccines, which should be performed at least 3 weeks after immunization
Aiding in the evaluation of immunodeficiency
This test should not be used to diagnose tetanus infection

Reference Values
DIPHTHERIA TOXOID IgG ANTIBODY
Vaccinated: Positive (≥0.01 IU/mL)
Unvaccinated: Negative (<0.01 IU/mL)
Reference values apply to all ages.
TETANUS TOXOID IgG ANTIBODY
Vaccinated: Positive (≥0.01 IU/mL)
Unvaccinated: Negative (<0.01 IU/mL)
Reference values apply to all ages.
Interpretation
Diphtheria:
Results of 0.01 IU/mL or more suggest a vaccine response.
A diphtheria toxoid booster should be considered for patients with antidiphtheria toxoid IgG values between 0.01 and less than 0.1 IU/mL.
Tetanus:
Results of 0.01 IU/mL or more suggest a vaccine response.
A tetanus toxoid booster should be strongly considered for patients with antitetanus toxoid IgG values between 0.01 and 0.5 IU/mL.
Some cases of tetanus, usually mild, have occasionally been observed in patients with a measurable serum level of 0.01 to 1.0 IU/mL.
