Your doctor may recommend allergy testing to find out what might be causing your atopic dermatitis. Allergy testing is most helpful for people with atopic dermatitis who also have respiratory allergies or asthma.
Testing can also help find out if certain foods, such as eggs or nuts, are making the condition worse. Talk with your doctor about testing for allergies before making dietary changes.
If a specific allergen is thought to trigger your atopic dermatitis, you and your doctor will discuss how to remove it from your diet or environment while closely observing and recording your symptoms.
