Skin Preparation

Training Modules
Before beginning the cleaning process for the application site, the Trained Observer should wear a new pair of disposable gloves.
Select the area for the Sweat Patch and Overlay application. Vigorously clean a 6-inch by 6-inch area of skin using at least two 70% isopropyl alcohol wipes. Your kit provides one alcohol wipe for each PharmChek® Sweat Patch and one for each PharmChek® Overlay.
Since the alcohol is essential for removing oils, dirt, and dead skin cells, it’s crucial to thoroughly cleanse the area before applying the PharmChek® Sweat Patch and overlay.
Cleanse the chosen spot vigorously with an alcohol pad, using a gloved hand. Ensure the area is completely clean by checking the alcohol pad’s surface. If the pad shows discoloration, continue cleaning with a new alcohol pad until the pad remains clean and without any discoloration.
It is essential to allow the skin to dry for a minimum of 60 to 90 seconds prior to applying the PharmChek® Sweat Patch. Inadequate drying of the alcohol will result in poor adhesion of the Sweat Patch to the skin, subsequently reducing its wear time.
Applying the Sweat Patch before the alcohol has fully evaporated can lead to an alcohol burn or cause reddening of the skin surface.
