Testing technique Ppt: The GreerPick™ will be loaded with extract and inspected to ensure that a small droplet of extract is present at the tip of the device. While holding it at a 45 degree angle to the skin at the test site, the tip will be brought in contact with the skin. The tines will be pressed making contact with the superficial skin, withdrawing with a slight lifting of the skin. A properly applied prick test will result in a small pricking of the epidermis, but will not result in bleeding. The device will be discarded into a suitable biohazard container.
