IMPORTANT: Lead dust testing can be divided into two categories:

Qualitative Testing - Is there lead? Yes or No? This gives a low cost, chemistry-based indication for regular house and individual use. These kits are usually available in DIY stores BUT it is not sufficient for CLAW compliance purposes. Research has shown that this method of testing lead dust is unreliable and can give inaccurate and false results.

Quantitative Testing - (If there's lead) How much lead? This is the method used in order to meet The Control of Lead at Work 2002 (CLAW) compliance requirements. Quantitative is the most accurate and precise form of analysis. The Lead Check Professional Lead Dust Test Kit is a full quantitative analysis of dust samples.
