1. A method of collecting an analyte contained in the perspiration of a mammal using a dermal patch, comprising the steps of:
- a. placing a dermal patch on the skin of a mammal, wherein said patch comprises an absorbent material for collecting analytes contained in the perspiration of said mammal;
b. generating heat by means of a chemical composition in order to heat the skin of said mammal underneath said dermal patch, wherein perspiration flows through the skin of said mammalc. collecting an analyte present in the perspiration of said mammal in said absorbent material of said patch;
d. removing said patch after a sufficient period of time has elapsed following the initial application of heat to the skin of said mammal to allow said analyte to be detected in said patch by an assay for said analyte; and
e. detecting the presence of said analyte in said patch.

Abstract
A dermal patch including a means for generating heat on the surface of the skin of a subject wearing the patch. The temperature of the surface of the skin under the patch is raised to about 115° F., and perspiration is collected in the patch over the course of about an hour. The patch is then analyzed to determine the presence of an analyte in the patch.

12. A single use dermal patch for detecting an analyte contained in the perspiration of a subject mammal, said patch comprising:
-
an outer protective layer having an adhesive applied to one side of said layer, wherein said adhesive secures said outer protective layer to the skin of a subject mammal when said patch is worn on the subject'"'"'s skin; an absorbent material for collecting analytes contained in the perspiration of said subject, wherein said absorbent material is secured to the side of said outer protective layer to which said adhesive is applied, said absorbent material being in fluid communication with the skin of said subject when said patch is worn on the subject'"'"'s skin; and a heat-generating chemical composition, wherein said composition is secured to said outer protective layer or to said absorbent material of said patch, said composition being capable of reaching temperatures in excess of 105°
