Two reliable ways to detect lead-based paint are on-site X-ray fluorescence (XRF) testing and laboratory analysis of collected samples. XRF provides a quick, non-destructive screen by exciting the paint with X-rays and reading the characteristic emission from lead, which helps identify surfaces that may contain lead and prioritize further sampling. When precise confirmation is needed or regulatory thresholds must be met, samples such as paint chips or dust/wipe specimens are sent to a certified lab for quantitative analysis using established methods. This lab analysis gives exact lead concentrations, confirming presence and guiding remediation decisions. The other approaches listed don’t detect or quantify lead content in paint. Visual inspection can’t measure lead, and the remaining methods aren’t used for lead detection in paints.
