Reliable measurement is one of the pillars of regulatory science; however, measurement science does not start in the analytical laboratory. Rather, representative sampling plays at least an equal, if not more important, role in regulatory science. Addressed in the current issue of the Journal of Regulatory Science are several important aspects of sampling for regulatory decision making. One aspect that often escapes public awareness is the process to obtain a representative sample for follow-up analytical testing. The surveillance scheme, adopted by any regulatory agency or similar industry, shall be designed to collect defensible samples for analytical procedures . Another aspect is that the laboratory quality management system provides a systematic approach to produce reliable measurement results. (DOI assigned 7/3/2019)
