You can use Fluoro-Spec to test for lead virtually anywhere
Paint - If you live in a home that was built before 1978 there may be lead paint inside your home, Areas to test first are Friction Surfaces. Windows, Railings, Doorways, Doors & Floors are great places to start.
Ceramics- If you have any dishes that you eat off of and have designs or markings on them you may eat more lead than necessary. Lead that is in your dishes can get into your food or drinks that come in contact with the surface. -Hot acidic liquids are the worst-
Dust - If you have a lead hazard you would have dust. There's no getting around it, Dust gets into our bodies easily. Start with areas near Friction Surfaces. Your Vacuum cleaner or dust pan/ broom are great places to look next.
Water Pipes- Lead in your water comes from the pipes, if you have no lead in your plumbing you don't need to worry. Test your Water Service Line.
