Abstract：In order to improve the accuracy of the detection of boldenone in chicken by ultra-high performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS), a method for uncertainty evaluation was established. Based on the established mathematical model for uncertainty evaluation, the uncertainty components arising from the analytical process were determined and evaluated by statistical analysis. The standard uncertainty was synthesized, and the extended uncertainty was calculated according to the probability distribution. It was found that calibration curve fitting and standard solution preparation made the greatest contribution to the uncertainty. When the boldenone residue in chicken was 7.425 μg/kg, the expanded uncertainty was 0.754 μg/kg (k = 2).
