Abstract
An allergy testing technique for testing a patient for a plurality of substances includes a first member having a plurality of pik engaging portions arranged for selectively engaging respective piks for pricking or piercing the skin of a patient in use. A resilient compressible member is coupled to the first member for controlling a downward movement distance of the first member and for consequently controlling a downward movement distance of the piks. A well tray has a plurality of receptacles for receiving substances for which a patient is to be tested. The first member with the piks engaged thereon, is engageable with the well tray for causing the piks to contact substances in respective associated receptacles, the first member being thereafter removed from the well tray. The first member is then placed against the skin of a patient and is pressed downwardly (either straight down or with a rocking motion) against the skin of the patient to compress the compressible member and to cause the piks to contact the skin of the patient and to apply the substances at respective spaced apart positions on the skin of the patient. The first member preferably has a plurality of openings ther…
