Method Description

The Anti-Diphtheria Toxoid enzyme-linked immunosorbent assay (ELISA) and Anti-Tetanus Toxoid ELISA provide quantitative in vitro assays for detection of human IgG-class antibodies to diphtheria and tetanus toxoid, respectively.

 

The test kits contain reagent wells coated with either diphtheria or tetanus 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second incubation is carried out using an enzyme-labeled antihuman IgG (enzyme conjugate), catalyzing a color reaction.(Unpublished Mayo method)
