Division of Allergy & Clinical Immunology

Rafeul Alam, MD, PhD Division Chief

What do we do?  We provide comprehensive diagnostic and therapeutic services to patients with a broad range of allergic and immunologic disorders, such as food allergy, asthma and immunodeficiency. We are a specialized referral center, and our patients are typically referred by their local doctors/specialists because of difficulty in diagnosing and/or treating the disease.

Why National Jewish Health? Our nationally-recognized allergy and immunology specialists perform unique consultative services to provide comprehensive clinical care to our patients. These consultative services include pulmonary rehabilitation, psychosocial medicine, occupational medicine, speech therapy for vocal cord dysfunction, sleep studies, interstitial lung disease and nutrition.

The divisional basic science and clinical research labs provide a unique opportunity to conduct molecular diagnostic studies on patient samples that aid diagnosis as well as management of a broad-spectrum of allergic, immunologic and respiratory illnesses.
