My Egg Challenge


Please bring one or both of the following items:

  • 1 large scrambled egg. Okay to use salt and pepper.

  • 1 piece of homemade French toast with one egg absorbed in and around 1 piece of bread (that does not contain any of the patient's food allergens). It is okay to bring syrup or powdered sugar to add.

  • ***It is preferred that scrambled egg or French toast is not prepared by a restaurant if they cannot guarantee there is one total egg used.

  • 60 mL or two ounces of pasteurized liquid egg white.  Use any brand that only has liquid egg white as the ingredient and has 5 grams of protein per serving.  "Muscle Egg" may be found on with different flavors IF the ingredients show there are 26 grams of protein per one cup (237 mL) serving; flavors include cake batter, vanilla, mint brownie, strawberry, chocolate.




Can we have a Food Challenge if the patient is sick?

If the patient has a fever, flu-like symptoms, cough, wheeze, hives, worsened eczema, widespread rash, throat symptoms, vomiting, or other significant illness symptoms, the procedure will most likely not be done.  Please contact the office to discuss symptoms and reschedule the challenge if needed.  You may also keep the appointment to have a full illness assessment and to determine if the food challenge should be cancelled.


Food Challenge guidelines and what to expect

  • Please stop using antihistamines beginning 3 days prior to appointment. There is no need to stop asthma medications or nasal steroid sprays. Please call the office if you are unsure what medications to stop.

  • No food should be given to the patient 2 hours before arriving for challenge. Clear liquids are okay.

  • Please be prepared for the challenge appointment to last 2 to 4 hours.

  • The patient will be given small, increasing doses of the product every 15 minutes until a full serving size has been ingested. We will watch closely for any signs of a reaction, and vital signs will be taken before each dose and for an observation period after the last dose.


What are the risks of having a Food Challenge?

An allergic reaction may happen. The reaction may be similar to the patient’s first reaction or it could include new symptoms. Symptoms may include hives, swelling, shortness of breath, wheezing, coughing, vomiting, or diarrhea.


What happens if patient has a reaction?

The practitioner will examine the patient, and depending on symptoms, medications may be given such as antihistamine, anti-inflammatory steroid, or an epinephrine injection in the thigh. The patient will stay extra time for observation until stable to leave the office.


Expectations after passed challenge

  • The patient will be cleared to eat the food item 24 hours after challenge is completed.

  • The food should be included in patient’s diet at least once a week or as directed by the practitioner.

  • Follow up with your practitioner with any other questions or concerns.
