Methodology: Immunoassay
Clinical Significance: This procedure is based on a fluorescent enzyme immunoassay (FEIA) technique. The allergen of interest, covalently couple to an Immunocap, reacts with the specific IgE in the patient serum. After washing away non-specific IgE, enzyme labeled antibodies against IgE are added to form a complex. After incubation, unbound enzyme anti-IgE is washed away and the bound complex is then incubated with a developing agent stopping the reaction, the fluorescence of the eluate is measured. The higher the fluorescence value, the more specific IgE is present in the specimen. To classify test results fluorescence for patient samples are compared directly with fluorescence for the reference serum in parallel. Results are reported in both KUI/mL and % binding (alternate scoring method – ASM) with a class score.
