A light-initiated chemiluminescent assay for the detection of children's milk protein-specific IgE with excellent ability to avoid interference of specific IgG

The detection of allergen-specific IgE is of value for the diagnosis of children''s milk allergy. However, its accuracy will interfere with the presence of high levels of specific IgG in the serum of children with milk allergy. To solve this problem, we established a light-initiated chemiluminescent assay (LICA) based on nanomicrospheres, which neutralized the interference of specific IgG by increasing the amount of antigen coated on the microspheres. The ability of this method to resist IgG interference was confirmed by adding extra specific IgG to the serum of allergic patients. Finally, the positive rate of allergen-specific IgE was increased to 85%, which was better than the indirect ELISA (70%), indicating that this method has certain advantages for the detection of specific IgE in children with milk allergy.
