Comparison of the Multi-Test II and ComforTen allergy skin test devices.

The performance of different devices for percutaneous allergy skin testing may have statistically and clinically significant differences. We compared two multihead allergy skin testing devices: Multi-Test II (Lincoln Diagnostics, Decatur, IL) and ComforTen (Hollister-Stier Laboratories, Spokane, WA). Skin tests with glycerinated histamine (6 mg/mL base) and glycerinated saline were applied to 30 adults using Multi-Test II on the volar surface of one forearm and ComforTen on the opposite forearm.
