Whether your sample is collected with a wipe or a vacuum, it should be sent to a laboratory certified by either the NLLAP or ELPAT. To be sure the laboratory is certified to analyze for lead in dust, call the National Safety CounciTs National Lead Information Clearinghouse (NLIC) hotline at 800-424-LEAD or one of the agencies that run the accreditation programs, listed in Appendix B, under Testing/Laboratory Analysis. 

Results of XRF testing will generally indicate whether the paint tested is safe (below a certain cutoff) or hazardous (above a certain cutoff). Some XRF results, however, may fall between the two cutoffs and be inconclusive. In that case, a paint chip will be sent to a laboratory to be analyzed, as described above. For detailed information on specific XRF instruments, call the National Lead Information Clearinghouse, listed in Appendix B, under Testing/Laboratory Analysis. The NLAC, listed in Appendix B, under Inspectors/Risk Assessors, is compiling a list of proficient XRF operators.
