Preparing for Your Visit

Allergy & Immunology Clinic

Depending on your child’s symptoms and after consulting with the medical provider, your child may undergo same-day testing during the Allergy & Immunology Clinic visit. Be prepared for the visit to last from one to four hours in order to complete the necessary testing.

There are certain medications that interfere with the testing, and it is very important that your child stop taking the medication(s) before the appointment. If your child is unable to stop taking one of the medication(s) or if you have any questions, please contact the clinic at 602-933-4063.

If your child is taking any of the following allergy medications (in pill or liquid form, nasal spray, or eye drops), please stop five (5) days before the visit:
