Correlation of immediate skin test responses to antigens introduced by multi-test and intracutaneous routes

The Multi-Test applicator is a disposable plastic device for the simultaneous prick-puncture administration of different antigens at eight sites, in a rapid, relatively painless and reproducible manner. To determine its utility in immediate or reaginic skin testing, it was compared with the intradermal technique in children and adults. Skin test responses to glycerinated inhalant antigens, 1:20 or 1:10 W/V, administered by Multi-Test were comparable to those obtained from the same antigens applied intradermally in aqueous dilutions of 1:1,000 or 1:1,500 W/V.
