Understanding Allergies and Sensitizations Study

This study aims to improve how doctors diagnose allergies and understand the body's responses to them. Researchers are looking at different aspects of allergic disease, including cellular (related to cells), humoral (related to fluids in the body), genetic (related to genes), and physiological (related to how the body works) changes. The study is observing people with and without allergies to learn more. Success will be measured by evaluating food allergen responses using skin testing after one year. The study is currently unclear on its recruitment status and plans to enroll 2500 participants. Anyone from 1 week to 90 years old with a possible allergy can join, as long as they don't have special risks with blood draws (venipuncture).

Study design

What's involved
Participants will undergo skin testing to evaluate food allergen responses. This will be measured at 1 year.
Compensation
