How is food protein-induced enterocolitis syndrome (FPIES) diagnosed?

ANSWER

This is a rare food allergy in young children. Your baby may throw up over and over and get diarrhea several hours after eating.

In some cases, blood tests and atopy patch tests (APT) can help show what's wrong. For an APT, a metal cap containing possible trigger food is left on your child's skin for 48 hours to check for a reaction. But these tests can't confirm that your child has FPIES.

The only way to tell for sure is to do something called an oral food challenge, or OFC. Your child will eat foods you think may be triggers to see if there's a reaction. This will be done in a clinic or hospital.
