Official title
Food-specific Immunoglobulin G4 and Immunoglobulin E Antibody Reactions in a Population With Adverse Reactions to Foodstuffs-related Symptoms
Overview
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.
Interventions
- Diagnostic test Food-specific Immunoglobulin G4 and/or Immunoglobulin E antibody reactions
Immunoassay kits (NutriSMART® and Fastcheckpoc20® In-Vitro Diagnostic kits, DST GmbH, Schwerin, Germany) are performed in a population with suspicion of having a food allergy or a food intolerance with related symptoms.
Primary outcome measures
- Food-specific Immunoglobulin G4 antibody reactions [Time frame: 0 days]
Secondary outcome measures (1)
- Food-specific Immunoglobulin E antibody reactions [Time frame: 0 days]
