Reference Values
Vaccinated: Positive (≥0.01 IU/mL)
Unvaccinated: Negative (<0.01 IU/mL)
Reference values apply to all ages.
Interpretation
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.
Method Description
The Anti-Diphtheria Toxoid IgG enzyme-linked immunosorbent assay provides a quantitative in vitro assay for detecting human IgG-class antibodies to diphtheria toxoid. The test kit contains reagent wells coated with diphtheria toxoid. In the first reaction step, diluted patient samples are incubated in the wells. In the case of positive samples, specific IgG antibodies will bind to the antigens. To detect the bound antibodies, a second incubation is carried out using an enzyme-labeled antihuman IgG (enzyme conjugate), catalyzing a color reaction.(Unpublished Mayo method)
