Read More About Pediatric Allergy & Immunology

Nemours’ pediatric allergists diagnose and treat asthma and all types of allergies in children, from hay fever to food allergies. Our immunologists (doctors who specialize in malfunctions of the immune system such as autoimmune diseases, hypersensitivities, immune deficiency and transplant rejection) have a high level of expertise in diagnosing and treating immune system conditions in children, such as immune deficiency.

We’ll perform a complete exam and ask about symptoms, severity and timing. And we’ll work closely with Nemours’ experts from other pediatric specialty areas to provide a long-term management plan tailored to your pediatric allergy, asthma, or immunology needs.

How to Prepare
Before Your Child’s Allergy and Immunology Appointment

Here are some important tips to follow before your child’s appointment with our asthma, allergy and immunology team:

  • Stop all antihistamines, if possible, 7 days before your appointment — they interfere with skin testing. This includes medicines such as Zyrtec, Claritin, Clarinex, Allegra, Benadryl, Hydoxyzine, Periactin, Chlorpheniramine and most over-the-counter cold medicines.
  • Continue all asthma medicines, especially any inhalers. DO NOT STOP medicines such as Flovent, Advair, Singulair or Pulmicort.
  • If your child is on antidepressants, please call us because some antidepressants will interfere with skin tests. DO NOT STOP these medicines without speaking to us.

If you have questions, please call our office at (215) 861-8830.

What to Expect at Your Child’s Visit

At your first visit, our board-certified doctors, physician assistants and nurse practitioners will perform a complete medical and family history assessment, as well as a comprehensive physical exam. We’ll also ask many questions about your child’s symptoms, their severity and timing. (For example, do they appear or tend to get worse at a certain time of the year, after eating a certain food or during exercise?)

Based on our findings, and to help diagnose your child's problem, we may then perform further tests, such as:

  • Skin testing: Lightly scratching the skin with a potential allergen (a substance that can cause an allergic reaction, such as  pet dander, dust, pollen and foods) and then evaluating the skin’s response.
  • Patch testing: Applying various adhesive patches that each contain a potential allergen to the skin and then checking the skin’s reaction 48 hours later.
  • Food challenges: Feeding your child small amounts of a food suspected of being an allergen in the presence of a doctor, who can evaluate and, if necessary, safely counteract any allergic response. (We only do this if we’ve determined it’s safe for your child. This kind of testing should never be done at home.)
We also may order:
  • tests for drug allergies (allergies to various medicines)
  • blood tests that check for specific antibodies (cells made by the immune system in response to certain allergens)
  • tests that evaluate the overall function of the immune system
  • spirometry, chest X-rays and other diagnostic evaluations to check your child’s lung function
Frequently Asked Questions About Skin Testing
Q: Does it hurt?

Skin testing may sound scary, but it’s actually pretty simple and painless. Small plastic applicators are used to scratch the skin’s surface with the allergens. There might be some itchiness that goes away quickly.

Q: How do you know which allergens to test for?

Your child’s medical history will help your doctor or nurse determine which type(s) of skin testing your child might need.

Q: Where does my child have to go for skin testing?

The testing is usually done in our office. A nurse generally administers the test and your doctor interprets the results.

Q: How long does it take?

Testing typically takes between 30 and 60 minutes. Tests usually detect immediate allergic reactions, which develop within minutes of exposure to an allergen.

Q: Where on the skin is the testing done?

The tests will be applied to your child’s forearm or back, depending on your child’s age.

Q: How is the testing done?

The nurse will then apply drops of allergen extracts (pet dander, dust, pollen, foods, etc.) on your child’s skin. These will then be scratched into the skin's surface. After we’ve looked over the test results, the nurse or doctor will talk to you about what the allergies are and how to best avoid the related allergens.

If you have any questions or concerns before or after skin testing, please call our allergy nurses.

What You Should Know About Patch Testing

For testing that needs a longer time period (days instead of minutes), we’ll use patch testing.

Here’s how it works:
  1. We’ll apply the patches onto your child’s skin, usually on the back.
  2. We’ll place patches with suspected allergens onto your child’s back and secure them with tape.
  3. Your child will then need to wear the patches for 48 hours. Showers, swimming and strenuous activity should be avoided so the patches stay in place. (Sponge baths are OK, as long as the back is not disturbed.)
  4. Your child will then come back to see us at or after 72 hours to have the patch testing area read.
Can Kids With an Egg Allergy Get Vaccines?

Because certain vaccines are made by growing viruses on chicken egg cells, some children can have a reaction. Specifically:

  • Flu vaccine: If your child has had a severe reaction after eating eggs or a reaction to the flu shot itself, you should have your child evaluated by our allergists. We can then administer any flu shots, if needed.
  • MMR (measles, mumps, rubella) or varicella (chickenpox) vaccines: According to standard vaccination guidelines, children with an egg allergy should be able to get the MMR or varicella vaccines with little or no risks. However, if your child’s primary care pediatrician is uncomfortable administering the vaccinations, we can give them at our office.
