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.
