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).

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.

Eligibility

Inclusion Criteria:

  • Adults (>18 years of age)
  • To present symptoms related to adverse reactions to foodstuffs (ARFS)

Exclusion Criteria:

  • Antibiotic treatment

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?
