Biobanking for Biomarkers In Respiratory Disease, Allergic Diseases and/or Mast Cell Disorders

Summary

This study aims to build up a clinico-biological bank of samples from patients suspected of or suffering from allergic diseases (including asthma) or mast cell diseases in order to support future research in the field of allergic diseases. The biobank will help to identify new prognostic, diagnostic and/or predictive biomarkers.
