The critical role of allergen-specific IgE, IgG4 and IgA antibodies in the tolerance of IgE-mediated food sensitisation in primary school children

Figures & data

Figure 1.  The IgG4/IgE and IgA/IgE ratios in the allergen-specific IgE-positive school children and in the allergen-specific IgE-negative school children.

Figure 2.  The IgG4/IgE and IgA/IgE ratios in the allergen-specific IgE-positive school children and in the allergen-specific IgE-negative school children.

Table 1. The positive rates of specific IgE antibodies and the mean value of specific IgG4, specific IgA against the food allergens.
