Limited use: Skin testing for allergy is of limited usefulness even when a person does not have dermatographism. The history is the key; skin testing can be confirmatory. Especially, don't conclude that you must severely limit what you do and eat, and where you go, based on skin testing. It's just one piece of information that helps guide decisions.
