Non-hazardous swabs provide a rapid, sensitive and specific test for leachable lead on any surface. When lead is detected, LeadCheck® Swabs and/or the surface being tested turns pink or red on contact, depending on the concentration of lead present. In the vast majority of test situations results are obtained in less than 30 seconds. When detecting low levels of lead, or lead chromate containing pigments, results may take longer to develop. Each kit contains test confirmation cards to verify individual test results.
