Diagnostic Evaluation

Do consider:
Secondary bacterial infections with disease exacerbations
Food allergies for patients <5 years old with refractory AD despite optimal treatment and/or clinical history of allergic reaction to certain foods
Contact dermatitis for refractory AD despite optimal treatment, especially if involving the face, hands, and/or feet

Don't do these:
Bacterial culture unless looking for bacterial sensitivity
Food allergy testing on a routine basis
Patch testing unless allergic contact dermatitis is suspected, AD is refractory, or there is unexplained increase in symptom severity
