Assessment of the patient suspect of atopy.

A retrospective chart analysis of patients referred to the allergy service was undertaken to determine which historical and laboratory data most closely correlated with the presence of atopy. The serum IgE level was highly significant for all patients when analyzed as a group (P less than 0.0001). Other factors assumed significance when the patients were analyzed by individual age groups. Guidelines for the logical assessment of the child suspect of atopy are proposed.
