FDA Total Diet Study (TDS): Analytes and Analytical Methods

FDA Total Diet Study (TDS) Main Page

As part of the modernization of the FDA Total Diet Study (TDS) we moved from single-analyte to multi-analyte methods to analyze TDS samples. The move to multi-analyte methods has provided us with more sensitive methods (able to detect lower concentrations), more accurate methods (these methods are prone to less interference and are therefore considered more robust) and more efficient methods (cost effective).

We group the analytes measured in the TDS into three broad categories: elements (both nutrient elements and toxic elements), pesticides and radionuclides.
