Interventions

DIAGNOSTIC_TESTFood-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.
