Which program accredits laboratories for lead analysis testing?

• A. NLLAP
• B. ISO 17025
• C. EPA Certification
• D. OSHA

Answer: (A)

Accreditation for labs performing lead analysis is handled by the National Lead Laboratory Accreditation Program. This EPA-administered program is focused specifically on ensuring laboratories that test for lead—across typical environmental samples like paint, dust, soil, and water—meet the required method-specific QA/QC standards, participate in proficiency testing, and undergo on-site assessments of their quality systems and technical competence. This targeted approach gives confidence that lab results are reliable for regulatory decisions and health assessments. General ISO 17025 accreditation is a broader standard many labs pursue for overall competence, but for EPA-recognized lead analysis, the dedicated NLLAP is the applicable program. EPA Certification relates to lead-based paint activities and workers, not lab accreditation, and OSHA deals with workplace safety rather than accrediting laboratories.
