Exams and Tests
Most cases of
atopic dermatitis can be diagnosed from a medical
history and a physical exam. You will be asked about your family history of
allergic conditions, when the itch first started, and when the rash first
appeared. What the rash look likes and where it is located will help your
doctor make a diagnosis. Your or your child's condition is more likely to be
atopic dermatitis if a parent or brother or sister has an allergic condition
(especially
asthma,
allergic rhinitis, or atopic dermatitis).
Allergy testing
Your doctor may recommend
allergy testing to identify any factors that are
related to atopic dermatitis flares. Allergy testing is most helpful for people
with atopic dermatitis who also have respiratory allergies or asthma. Allergy
testing can help identify certain
allergens. But test results are often
false-positive. For more information, see the topic
Allergy Tests.
If a specific allergen is
thought to trigger your atopic dermatitis, you and your doctor will discuss how
to eliminate it from your diet or environment while
closely observing and recording your symptoms.
