title: "Reactions" to standard patch test materials.
abstract: Twelve compounds tested by closed patch test at recommended concentrations produced numerous "Fallse positive" non-allergenic reactions in a panel of 100 vollunteers. These results indicate the need for further basic studies to determine appropriate non-irritating concentrations of materials used in biagnostic patch testing for contact allergy.
