Advanced diagnostic tools

Allergic conditions can be complex to diagnose and stressful for families who are waiting for answers. There are many internet myths regarding allergies. To ensure patients are diagnosed quickly and accurately, we offer the most advanced diagnostic procedures for children.  We can help you navigate the mythology and confusion and determine precisely what type of allergy is affecting your child. Not all allergy diagnostic tests are accurate in children. The high volume of conditions we treat, coupled with the advanced diagnostic tools we offer, leads to more accurate diagnoses, customized treatments, and children feeling better, faster.

Immunologic conditions can be mysterious and frightening for a child. Often there can be infections and autoimmune diseases that are just chalked up to “bad luck”. Our Immunologists utilize the most advanced testing to characterize your child’s immune system with unprecedented accuracy. Genetic testing is widely used to understand the basis of a child’s condition. The Immunology program at CHOP is the largest in the United States and the experience and high standards make it possible to develop a therapy plan that uniquely fits each child’s goals.
