Objective: Teicoplanin, a glycopeptide antibiotic, is used to treat infections caused by Gram-positive pathogens. Trough-level monitoring of teicoplanin is recommended in specific -patient populations, including critically ill patients. This study aimed to develop and validate a liquid chromatography-tandem mass spectrometry (LC-MS/MS) method to quantify teicoplanin in human plasma and adapt the method to a critically ill patient sample. Materials and Methods: -value of <0.05 was considered statistically significant. Results: >0.05). Conclusion: The LC-MS/MS assay validated in this study is high-throughput, robust, and quick enough to be implemented in clinical therapeutic drug monitoring (TDM) laboratories. More large-scale studies are needed to understand better the relationship between teicoplanin trough levels and patient-related factors.
