Food Allergy | Diagnosis and Treatment

How is a food allergy diagnosed?

The first step to diagnosing a food allergy is a complete medical history. The allergist will perform a physical exam and ask questions about your child's symptoms to see if they are related to a food allergy. A series of tests or procedures may be performed to help identify a food allergy. The results — although not always transparent — will be reviewed along with your child's medical history to provide a diagnosis. Tests and procedures may include: 

  • food diary
  • skin-prick test
  • elimination diet
  • blood test

What are the treatment options for food allergies?

There is no medication to prevent food allergy. After your child's physician discovers which foods your child is allergic to, it is important your child avoid these foods (and other similar foods). If you are breastfeeding, you too must avoid foods that your child is allergic to. 

The physician may prescribe an emergency kit which contains epinephrine, which helps stop the symptoms of severe reactions. Some children, under the direction of a physician, may be given certain foods again after three to six months to see if he or she has outgrown the allergy.
