Atopic Dermatitis - Eczema

How is the condition diagnosed?

The healthcare provider will usually obtain a family and personal history of allergy-related conditions. A thorough exam will usually be done to examine the rash and rule out any other possible causes for the rash. The provider may take a sample of fluid oozing from a lesion and send it to the laboratory to identify what organism is present.

Sometimes a biopsy of the lesions may be done. For a skin biopsy, the provider takes a small sample of skin and sends it to the laboratory to rule out other causes. If the rash continues, blood tests may also be done.
