LeadCheck® Swabs provide a rapid, sensitive and specific test for leachable lead on any surface. Results are typically obtained in less than 30 seconds. When lead is detected, the swab and/or the surface being tested turn pink or red on contact, depending on the concentration of lead present. Each kit contains test confirmation cards to verify individual test results. LeadCheck® Swabs have outperformed other screening methods in every government evaluation conducted over the past 15 years.
