Drawing upon the recovery rate and variability coefficient garnered from milk spiking, the accuracy and precision were evaluated. Four concentrations (0.2, 10, 20 and 40 ng/g) of blank milk were spiked to determine recovery rates. Analyzing six replicates of QC concentrations within the same day and evaluating five measurements of QC concentrations over five consecutive days assessed the accuracy and precision of the UPLC-MS/MS method.
