Answer

Blinded food trials are the criterion standard for determination of food hypersensitivity. However, no adequately studied reports exist of the incidence of food sensitivity or the effect of food restriction on the eczematous dermatitis of Wiskott-Aldrich syndrome. The radioallergosorbent assay test (RAST) for food sensitivity is insensitive, and findings often do not correlate with clinical symptoms.
