PharmChek® Sweat Patch Products
PharmChem Inc. manufactures the PharmChek® Sweat Patch and the PharmChek® Overlay. These components work together to create a continuous monitoring device that is difficult to manipulate, alter, or replace. When worn on the skin any signs of drug usage throughout this period are collected in a cellulose pad, which is then sent to our UK laboratory for analysis.
