<![CDATA[Laboratory results are one of the supporting aspects in describing the patient's condition in real-time. High-quality results can be reviewed through technical aspects. One that can be done is internal quality control, which aims to monitor the smoothness of a laboratory's quality system to achieve examination results with high-quality and reliable accuracy and precision. The laboratory quality control process includes pre-analytical, analytical, and post-analytical stages. The purpose of this study was to examine the precision and accuracy of quality control of triglyceride examination parameters. The research method used was quantitative analytical observation with a cross-sectional approach. This study was conducted at Wangaya Regional Hospital, Denpasar City, with daily control data collection for the period 1-31 August 2025. The data obtained were then processed using Microsoft Excel and analyzed using Westgard multirole. The results of quality control of triglyceride examinations in August for precision (accuracy) values based on the Coefficient of Variation (CV) formula (3,72%), and accuracy (precision) values can be seen from the bias value (d%) of (-5,2%). The results of this study can be concluded that the CV value and bias value (d%) do not exceed the maximum value and it can be said that in August 2025 it has a high level of precision and accuracy. The achievement of quality accuracy and precision can be assessed through laboratory quality assurance including pre-analytical, analytical and post-analytical stages, based on this it is very important for a laboratory to carry out internal quality assurance (quality control) so as to create a sense of satisfaction to customers but also in accordance with operational provisions and professional codes of ethics that have been determined.]]>
