If inconclusive results are encountered, which entity is typically responsible for confirming them unless the client requests otherwise?

• A. The inspector
• B. The client
• C. The local regulatory agency
• D. The laboratory

Answer: (D)

When a result is inconclusive, the laboratory is the right party to confirm it because labs use validated methods, QA/QC procedures, and proper chain-of-custody to verify findings. They have the specialized equipment and standardized analyses needed to resolve an inconclusive measurement with reliability. The inspector’s role is to collect data and report results from the field, not to perform definitive confirmatory analyses. The client can request alternative verification or a second lab’s analysis, but by default the confirmation comes from the laboratory responsible for the analytical work. Regulatory agencies oversee compliance and reporting, but they don’t typically perform the confirmatory testing themselves.
