Are home lead test strips accurate?
Test strips and kits can show whether lead is present above a certain level, but they are not as accurate as a certified lab. For a reliable number, especially with children or pregnancy in the home, use a certified lab.
How do I take a sample for a lead test?
Labs usually ask for a first-draw sample: the first liter of cold water from the kitchen tap after the water has sat unused for at least six hours, collected in the bottle the lab provides. Follow the lab's instructions exactly.
