* Please note that 3M no longer manufactures Lead Check Swabs. 3M sold the formulation and trademarks related to 3M™ LeadCheck™ Instant Lead Tests to Luxfer Magtech. The U.S. Environmental Protections Agency  recognizes the Leadcheck™ test kit made and distributed by Luxfer Magtech. You can continue to use 3M™ LeadCheck™ test kits you have on hand. We have a limited supply of 3M branded Lead check swabs remaining so future Lead Check Swab orders may be Luxfer branded. Click here to see the U.S. EPA announcement.
