Food Challenge for Extensively Heated Egg (HEFC)
The goal for a baked egg food challenge is for your child to eat a known quantity
of egg in a baked product, such as cake or muffin. The total dose for the challenge
is about ¼ of a baked egg. Follow the instructions for the cake mix suggested
below. If you do not use the recipe below, please bring in a copy of the recipe to
clinic the day of your challenge so we can best determine the amount your child
must eat to get the proper dose for the challenge. If your child has a wheat allergy,
you can use a gluten free cake or muffin mix that calls for 3 eggs and makes a
similar portion as the cake mix below. Please call clinic with any questions related
to your challenge food or recipe.
Prepare for the Baked Egg Challenge
1. Do not give antihistamines for 5 days before the food challenge. You may
still give diphenhydramine (Benadryl®), which can be used up to 24 hrs
before the food challenge.
2. Give other allergy and asthma medicines as usual.
3. If your child is sick on the day of the food challenge, call the clinic to
reschedule. Your child needs to be well for a food challenge.
4. It is best to bring a child’s favorite toy or item that will keep him or her
busy as the challenge can take a couple hours to complete.
