Special Services

Jeffrey Modell Diagnostic and Research Center for Primary Immunodeficiencies

The immunodeficiency at SSM Health Cardinal Glennon Children's Hospital is a referral center for the Jeffrey Modell Foundation (JMF) and Immunodeficiency Foundation (IDF). The division works with the Bone Marrow Transplantation Division in transplantation of severe T-cells.

Allergy Challenge Clinic

The Allergy and Immunology Division has developed special clinics to perform food and drug challenges to evaluate for these allergic diseases.

Asthma Center for Children

SLU's Divisions of Allergy and Immunology and Pulmonology formed an Asthma Center to provide care for pediatric asthma patients.

Eosinophilic Esophagitis Clinic
The division formed this clinic led by Dr. Bradley Becker to provide care for pediatric patients with eosinophilic gastrointestinal diseases.
Clinical Immunology Laboratory

The Allergy and Immunology Division maintains a Clinical Immunology Laboratory as a reference laboratory to pathology that is CAP and CLIA certified. The laboratory performs diagnostic cellular functional studies, including lymphocytes proliferation, cellular cytotoxicity and cytokine synthesis. In addition, specialized studies to analyze T-cell signaling, CD40L expression and NBT are available.

Community Service

Allergy and Immunology Division members are active in the Asthma and Allergy Foundation of America, St. Louis Chapter. The division helps coordinate with the AAFA St. Louis Chapter an annual asthma screening for at-risk participants in the St. Louis Cardinals' Redbird Rookies Little League.
