Lead paint
Yes, there are kits to test for lead in paint. I have seen them at local stores but not lately. Try a paint store. Unless you have small children , you can probably paint over leaded paint. To adversely affect you, the paint would have to be eaten or the dust from it breathed into the lungs. I don't think they have used lead in paint since the 80s. I worked at a tetra ethyl lead plant and that was when we shut down. bg
