Immunoglobulin G4 and Immunoglobulin E Antibodies in a Population With Adverse Reactions to Foodstuffs-related Symptoms

January 3, 2023 updated by: Lisset Pantoja Arevalo, Universidad Politecnica de Madrid

Food-specific Immunoglobulin G4 and Immunoglobulin E Antibody Reactions in a Population With Adverse Reactions to Foodstuffs-related Symptoms

The aim of this study is to analyze a population with symptoms associated with adverse reactions to foodstuffs (ARFS). To determine the levels of food-specific immunoglobulin G4 (IgG4) and immunoglobulin E (IgE) antibody reactions (AbR).

Detailed Description

Volunteers with symptoms related with adverse reactions to foodstuffs (ARFS) and suspicion of having a food allergy or a food intolerance are enrolled in this study. A 50μl of capillary whole blood is analyzed and the levels of food-specific immunoglobulin G4 (IgG4) or immunoglobulin E (IgE) antibody reactions (AbR) are determined.
