Quality Control and Assurance Issues Relating to Sampling and Analysis in a Total Diet Study
The integrity of TDS data is a function of food representativeness, laboratory competence, analytical validation and critical evaluation of laboratory data. This chapter deals with the analytical quality control and quality assurance procedures for handling total diet study samples and discusses the relevance of measurement uncertainties associated with evaluating the analytical data.
