Determining dihydropyrimidine dehydrogenase (DPD) activity by measuring patient's uracil (U) plasma concentration is mandatory before fluoropyrimidine (FP) administration in France. In this study, we aimed to refine the pre‐analytical recommendations for determining U and dihydrouracil (UH2) concentrations, as they are essential in reliable DPD‐deficiency testing.
