Participants will complete surveys and have blood draws during the study. Additionally, participants will be asked to keep track of their diet as well as introduce safe foods identified by the researchers.
The aim of this study is to validate a blood test that can identify safe foods for food protein-induced enterocolitis syndrome (FPIES). This study proposes a solution to the problems of FPIES by developing a new blood assay that screens a large number of foods (more than 20) in a culture plate. If this blood test is successful it may be able to identify safe foods more quickly.~The study will recruit ten participants that will have 2-3 trigger foods as well as ten participants with 4 or more trigger foods.
