IBL International’s Food intolerance ELISAs provide a useful tool for assessing an individual’s sensitization to food allergens.
The assays are intended for quantitative determinations of specific IgG or IgG4 in serum and plasma, and are intended as a supplementary test for the assessment of food sensitivities. In this scope, there is the option to select between IgG and IgG4 determinations.
Studies indicate that 55 % of patients show high titers of total IgG, whereas 39 % of patients show elevated levels of IgG4.
