Fig. 2. Scattered plots of food allergen sIgE concentrations, as measured by the ImmunoCAP® assay (x-axis) and the Allergy-Q® assay (y-axis). Each line in the plot represents class cut-off of each assay (class 0: <0.35, class 1: 0.35-0.7, class 2: 0.7-3.5, class 3: 3.5-17.5, class 4: 17.5-50, class 5: 50-100, class 6: >100 kU/L). Shaded boxes represent concordant areas in each concentration class. Each plot represents a food allergen: egg white (A), cow's milk (B), wheat (C), peanut (D), and shrimp (E). Fig. 2.
