[Application progress of liquid chromatography tandem mass spectrometry in precision medicine].

Liquid chromatography tandem mass spectrometry (LC-MS/MS) is an analytical method that combines high separation of liquid chromatography with high selectivity and sensitivity of mass spectrometry. In recent years, LC-MS/MS has been widely used in clinical practice, including screening of inherited disorders, determination of endogenous compounds and analysis of biomarkers. LC-MS/MS is of great value to the precision prevention, diagnosis and treatment of some diseases due to its accurate data. This article not only illustrates the advantages of LC-MS/MS in precision medicine, but also prospects the future trend of LC-MS/MS in clinical practice, which expects to promote the development of clinical LC-MS/MS in the prevention, diagnosis and treatment of diseases.
