The perceived obstacles in performing patch test to detect allergic contact dermatitis: a comparison between community allergists and directors of allergy training programs

Previous training in PT among PDs and community allergists was associated with a higher likelihood of performing PT. We recommend that training in the application and interpretation of PT for diagnosis of allergic contact dermatitis should be an integral part of the curriculum of allergy fellowship training programs and should also be incorporated into the continuing medical education program of practicing allergists. Furthermore, although allergists may continue to rely on dermatologists for more comprehensive PT, use of the thin-layer rapid use epicutaneous test is a simple screening tool that should be available to all allergy practices.
