Atopic dermatitis can be best diagnosed by: (A) Clinical evaluation, (B) Patch test, (C) IgE level, (D) Skin Biopsy
Answer is A. Atopic dermatitis best diagnosed by Clinical evaluation. The diagnosis of atopic dermatitis is rarely aided by investigations. Estimation of total serum IgE, specific radio- allergosorbent tests (RASTs) and prick tests usually serve only to confirm the atopic nature of the individual. Patch testing may also help to identify a contact allergen responsible for deterioration of the skin condition, paicularly in adults.
