Collect lead dust wipes on floors and windows sills. Send lead test materials to an LPAT-approved laboratory for analysis. Results are usually mailed back within a few days. Compare the results to the national standards listed below. Contact your state or county health department.
Some agencies provide testing services or maintain lists of services.
Use a home dust test kit. Call an environmental laboratory for a home test kit. Instant spot test kits can provide useful information, but are not as accurate as a test that uses a laboratory. Usually, two or three samples per room provide enough information. Having someone else come to your home to collect the samples costs more.
