Who will my child see?

  • Gastroenterologist
    Our gastroenterologist will review your child’s medical history with you and answer any questions you might have. He/she will also perform a physical exam and may recommend that your child have additional tests performed, such as an endoscopy or radiology study.

  • Allergist
    Our allergist will also review your child’s medical history with you, answer any questions you have and perform a physical exam. He/she may also recommend additional tests such as skin or blood tests.

  • Dietician
    We understand the frustration of restricting your child's diet due to food allergies. Our dietician will meet with you to make sure that you have the tools you need to make healthy dietary choices for your child.

  • Social worker
    Our social worker can provide coping support, connect you with the EGID community both locally and nationally, introduce you to support groups, and help you to be an effective advocate for your child with EGID.

  • Clinical Coordinator: Clinical Coordinator serves as your primary contact person to facilitate communication with your child's treatment team, schedule appointments and various activities to coordinate patient care.

What tests will be performed during my child's visit?

Any number of tests may be used to identify foods that may be triggering your child’s condition. These include skin prick tests, blood tests and food patch tests.

How long will my appointment take?

For new patients, the first visit typically lasts about 3 hours. Return visits are usually shorter than this. Tests may include endoscopy, skin prick, skin patch, blood tests, and barium swallow test.

Allergy Tests 

Identification of foods that may be triggering your child’s condition may be performed by any of the following methods described below. No test can definitively diagnose or rule out an allergy. All results need to be interpreted by an allergist in context of the medical history.

Skin prick tests

  • used to evaluate for food and environmental allergies

  • performed by applying a drop of suspected allergen on to the surface of the skin

  • a positive test will be seen within 15 to 20 minutes with a hive and redness at the test site

  • a positive test does not always mean your child is allergic to that allergen

  • not considered painful but positive reactions can cause itching which may be uncomfortable

  • some medications may interfere with skin testing and should not be taken prior to the allergy visit

Blood tests

  • commonly known as RAST tests

  • used to measure IgE antibodies to food and/or environmental allergens

  • may be used when skin tests cannot be performed

  • a positive test does not always mean your child is allergic to that allergen

  • does not predict the severity or the type of reaction, but gives information on the likelihood of having a reaction if exposed to a particular allergen.

Food patch tests

  • used to detect possible delayed-type food allergies

  • differs from the RAST blood test or skin prick tests, which are used to evaluate for immediate (IgE-mediated) reactions that may result in symptoms such as hives or anaphylaxis.

  • requires two separate visits to the Allergy Program

  • during the initial visit, a food patch test panel will be placed on the back of you/your child. These panels consist of prepared foods placed on shallow aluminum disks that are secured to your child’s back with tape. The selection of foods to be tested will be determined by your allergist.

Medication Guidelines 

If your child is taking medication, it is important that you follow these directions.

  • Do not give your child medicine that contains antihistamines prior to the visit.

  • Do not give your child the following medications for 7 to 10 days before your visit:

    • Allegra (Fexoferadine)

    • Claritin (Loratadine)

    • Clarinex

    • Clemastine

    • Tavist

    • Atarax (Hydroxyzine)

    • Cyproheptadine (Periactin)

  • Do not give your child Zyrtec for 10 to 14 days before your visit.

  • Antihistamines are found in many non-prescription cold or allergy medicines. These should be stopped at least 3 days before the visit. Examples are:

    • Benadryl (Diphenhydramine)

    • Actifed

    • Dimetapp

    • Pediacare

    • Triaminic cold formulas

  • If you do not know whether your child's medicine contains antihistamines, ask the pharmacist or call the Boston Children's Allergy Program at 617-355-6117 and ask to speak with a nurse.

  • If you are unable to stop the medication, or your child develops symptoms while off the medication, please call the Allergy Program at 617-355-6117 and ask to speak with a nurse.

  • Do not stop other medications prescribed by your doctor.

  • Do not give your child asthma medications (bronchodilators) such as albuterol, Ventolin, Proventil, Xopenex or Maxair on the day of the visit unless your child is coughing or wheezing. Other asthma medications and antibiotics should be given as usual.
