About the study

NIH investigators are conducting clinical research studies to learn more about what causes food allergy, what can be done to improve the care of patients with food allergy, and how to improve the ways food allergy is diagnosed and treated.

Volunteers are currently needed for a study that seeks to determine whether patients with food allergy are more likely to have nutritional deficiencies, and whether this depends on the type and number of food allergies they have.

What does the study involve?

The study involves at least two visits for a comprehensive food allergy evaluation and nutritional assessment, a full panel of nutritional labs encompassing a wide variety of vitamins/trace minerals, and noninvasive scanning to assess bone health (DEXA). Participants also meet with a dietician who provides individual counseling on nutritional needs and potential deficiencies.

Where is the study taking place?

The study is being conducted at the NIH Clinical Center in Bethesda, Maryland, which is accessible by car and public transportation.

Who can participate?

To be eligible for the study, patients must be at least 2 years old and have had an immediate reaction to a food, as well as positive skin prick testing and/or IgE testing to the food.

How much does it cost?

There is no charge to participate in this research study. All study-related medical care, including clinic visits and procedures, are provided free of charge. Medical insurance is not required.

Is payment provided?

Financial compensation will be provided to study participants and travel expenses may be reimbursed.
