DEVICE: ComforTen® 30-hole covered tray (00365044000059)

A sterile device with a sharp triangular cutting edge at the distal end designed to manually breach the epidermis to facilitate the diagnosis of allergic reactions in skin allergy testing performed by an allergist or other healthcare professional. It is held between the fingertips and pressed transiently, but firmly (not jabbed), at right angles through a drop of an allergen extract into the flexor side of the forearm of a suspected allergic individual. The tip penetrates only the most superficial layers of the skin allowing a small volume of the allergen extract to enter the skin and diffuse into the skin layers below. This is a single-use device.
