The 158 Foods IgE Panel provides an assessment of whole extract and specific IgE components. Whole extracts are used because a patient can potentially be allergic to any component of the whole extract. The inclusion of specific IgE components helps predict the likelihood of anaphylaxis and minimizes the risk of IgE reactions from cross-reacting foods.
Our IgE panels utilize a quantitative ELISA (enzyme linked immunosorbant assay) analysis of the specific immunoglobin IgE identified for the chosen diet panels’ food and spice analytes.
We follow a meticulous process to extract the critical component from each analyte (food and inhalant trigger) to ensure the antibody present in the patients’ sample will bind properly and validate results with positive and negative controls. Once attached to the antigens, antibodies are detected through spectrophotometric analysis, where the values are directly proportional to the concentration of the analytes in the sample. For additional accuracy, we perform duplicate testing to ensure there are no discrepancies.
