Collection of Tissue and Blood in Patients with Allergic and Immunologic Disorders

Overview

About this study

Allergic and immunologic disorders are very common but some are very poorly understood. Numerous studies of the epidemiology, characteristics, diagnosis and treatment of these disorders are urgently needed to identify and optimally treat affected patients. Though numerous challenges impact the progress of research in this area, specimens are needed to test new hypotheses and methodologies.  We aim to create a registry and biorepository of tissue and fluid specimens for future studies.
