Platelets are blood cells that are important in coagulation of the blood. These cells have recently been shown to play a role in a number of other biologic processes, for example inflammation. In this study the investigators will determine the extent of platelet activation in people suffering from common chronic skin inflammation-urticaria and allergic dermatitis.
