Abstract

Drug reactions area common problem in hospital inpatients and outpatients. Oral or parenteral drug challenges are valuable diagnostic aids, but time consuming. We review attempts to diagnose delayed hypersensitivity drug eruptions by patch testing. We review control data, and offer an operational definition that might make for greater acceptance of the rôle of diagnostic patch testing in this entity.
