Take me to SCFAI

Visit

Over the course of your child's 2-5 day Launch visit, your child will undergo a 24-hour patch test and meet with one of our physicians to review the results and their treatment plan, based on our analytics. They will also complete their first Food Challenge at this visit.

Your Launch Visits

Day 1: Patch Day

During day 1, a patch that contains physical food allergens will be placed on your child’s back. This enclosed patch will remain on your child’s back for 24 hours. This allows us to assess how your child’s GI tract reacts to various allergens. Please keep the patch clean and dry, avoiding any heavy activity and sweating during the test.

Day 2: Launch Day

During your Launch day your patch is removed and results are recorded while you meet with one of our physicians to review the results and your child’s treatment plan, based on our analytics. Our staff will thoroughly review your at-home dosing regimen with you, and your child will complete their first food challenge.

Day 3+: Additional Visits

Since each child’s plan is individualized, some patients may need additional visits
depending on their treatment plan.

If you have any questions about the program, our physician will be happy to answer those for you at this visit.

Additional Information

PROVIDERS
We have a team of expert providers who are here to help your child on their journey to food freedom. Please ask them any questions you have about the program, as they will be able to help you understand the reasoning behind everything we do to ensure your child’s safety and success.
WHAT DOES A CHALLENGE AND INTRODUCTION MEAN FOR MY CHILD?
A food challenge is a monitored office visit where your child will consume a large amount of a sensitized allergen followed by exercise to ensure safe consumption at home. After each challenge, these foods will move into your child’s maintenance plan.

Introductions are also monitored office visits where we will introduce a new conditioning food in small amounts. These allergens are always given in higher amounts in the office and will be monitored for 15 minutes. Introduction foods will be taken home and built up over the treatment weeks, then you will return for food challenge visits to challenge higher dose amounts.

Patch Test

What is a Patch Test?

Patch tests are used to detect possible food allergies and gastrointestinal sensitivities. The patch test measures conserved, innate immune responses to food allergens via the closed (air-tight) application of food allergens to the skin, followed by measurement of the immune response 24 hours later.

The patch test allows FAI to assess how the patient’s gastrointestinal tract reacts to various allergens, as the dendritic cells in the skin mimic those in the stomach. This test differs from ImmunoCap blood tests or skin prick tests, which are used to evaluate immediate reactions that may result in symptoms such as hives or anaphylaxis.

Combining patch testing and skin prick testing helps us identify foods that are causing allergic symptoms. As previously mentioned, a patch that contains physical food allergens will be placed on your child’s back. This appointment lasts approximately 30 minutes. This enclosed patch will remain on your child’s back for 24 hours, and the results will be ready the next day, at your Launch appointment.

 

What allergens are in the patch test?
The same allergens on the skin prick test are on the patch test. The patch test is testing for a different immune response than the skin prick test.
 
Will we need to repeat the patch test?
Generally, the patch test does not need to be repeated unless the test is compromised.

How to Prepare

On your first day, a food patch will be placed on your child’s back. To prepare for this day please bathe or shower your child the night before or the morning of the patch day appointment. Please avoid applying topical creams, ointments, or oils to the back as it can prevent appropriate adherence of the patch to the back area. For this test you may be on or take antihistamines as these will not affect these results.
 
Has anyone had anaphylaxis due to the patch test?
We have placed thousands of patch tests and have never had a patient who developed anaphylaxis due to a patch test.
 
Can I give an antihistamine if it is itchy?
Yes, you can give Benadryl if your child is experiencing itching, this will not interfere with the test results.

During the Patch Test

What type of activities should my child avoid during the patch test?
Avoid heavy activity and sweating during the patch test—no swimming, showering, or bathing. We recommend calm or relaxing activities so that the patch remains in place. We recommend keeping your child at home from school on this day. If you are concerned about not being able to shower, please have your child bathe before the patch appointment.
 
How do I care for the patch during the test?
Keep the patch clean and dry. Please avoid scratching or rubbing the patch as it can loosen the adherent surface.

Frequently Asked Questions

I heard that mustard scars the skin, can we omit mustard?
To best serve your child, we must collect all data and information. Having incomplete data/answers will limit our ability to treat your child safely and effectively. Therefore, mustard must be included on the patch.
 
MUSTARD IRRITATION CARE: Apply Bacitracin ointment on the site and also apply Aquaphor/ Vaseline as a barrier ointment.
 
What do I do if the patch comes off?
If the patch falls off or is removed earlier than scheduled, it must be repeated. Please contact us for further instructions.
 
What if my child develops hives or vomiting?
If your child develops any concerning symptoms please call the provider on call.

Pulmonary Function Testing

What is a PFT?

Pulmonary Function Testing (PFT) is a well-established modality of testing for evaluating lung volume, capacity, rates of flow, and gas exchange. An exhaled Nitric Oxide test (Fractional Concentration of Exhaled Nitric Oxide Oxide – FeNO) can assist with determining how much inflammation is present in the airways.

Why does my child need a PFT?

Children 7 years of age and older will have a Pulmonary Function Test (PFT) and exhaled Nitric Oxide (ENO) test completed. Children younger than 6 are generally not developmentally capable of completing the tests as they require a level of coordination. These tests are performed so that we can evaluate your child’s airway reactivity to identify potential complications in an effort to maximize safety.

How often will my child need a PFT?

These tests will be performed periodically through out treatment based on you child’s specific needs.

Why should my child avoid eating or drinking 1 hour prior to this test?

Eating or drinking may cause your child’s results to fluctuate.
