  • Patent number: 8420054
    Abstract: A method for measuring of histamine in an epidermis comprising applying an adhesive article to an epithelium of a mammal; allowing for adherence of epithelial cells to the adhesive article; removing the adhesive article from the epithelium of the mammal; preparing the adhesive article using standard laboratory methods for extraction; extracting histamine from the epithelial cells adhered to said adhesive article; measuring histamine from the epithelial cells adhered to said adhesive article; determining the amount of histamine in the epithelial cells as compared to a baseline sample. Further, a method of objectively measuring the perception of itch in mammals and wherein there is a reduction in histamine from a baseline level which is directly proportional to a reduction in an itch perception.
