FPIES is a non IgE food allergy that affects the gi tract. It is a delayed response rather than an immediate response. FPIES is considered rare and is usually outgrown in phases. For instance, a child may outgrow one trigger at age 3 and another trigger at age 5. It is important to note that there are no tests to confirm FPIES. There are only tests to rule out other conditions.
FPIES is diagnosed by an allergist, gastrointestinal doctor, or a pediatrician. In most instances, an allergist will perform skin prick allergy testing and/or blood allergy testing to rule out IgE food allergies first. Then, after taking a medical history and examining the child, the allergist will diagnose the child with FPIES. Your allergist should give you a letter for ER staff to make them aware of to treat your child in the event of an acute FPIES reaction. It is often the experience of parents that this is where the medical community involvement ends.
