What is the relationship between lab analysis and XRF results?

XRF gives fast, on-site screening of lead in paint and other surfaces, but its readings are not the final word in every situation. Lab analysis provides definitive quantification under controlled conditions and is used to confirm XRF results when regulations require it or when readings need validation. In practice, XRF identifies potential problem areas quickly, and lab analysis serves as the confirmatory standard to ensure accuracy, especially near action levels or when readings are uncertain.
