Who does not recommend use of lead spot test kits?

• A. EPA only
• B. HUD only
• C. Neither
• D. EPA and HUD

Answer: (D)

Spot test kits for lead are not reliable enough to base hazard decisions on. Both EPA and HUD discourage relying on these quick field tests to determine whether paint contains lead or to decide how to manage a property. The main problem is accuracy: color-change spot tests can produce false positives or false negatives because they’re affected by surface conditions, paint layers, contaminants, and interference from other metals. They don’t quantify how much lead is present and can’t distinguish different lead compounds or provide a defensible basis for regulatory action. Because of these limitations, the recommended approach is to use laboratory analysis conducted by an accredited lab using validated methods. Field screening may be used to guide where to focus attention, but it should not be used to make enforcement, abatement, or risk-assessment decisions. Since both agencies share this stance, the correct choice is that both EPA and HUD do not recommend the use of lead spot test kits.
