Chemical and/or Metal Patch Testing

Like the food patch test, testing can be performed to check allergies to certain chemicals or metals. A patch is simply placed on your back for 72 hours after the specific allergens have been added. The test is then read by our board-certified allergist/immunologist to interpret the results. This testing option is used for patients who experience speculated reactions from coming into contact with certain metals or chemicals.
