Quantitative analysis of endogenous and exogenous steroid hormones is an important step for our understanding of the causes of endocrine disorders in pediatric. In this study, we developed a method to simultaneously quantify endogenous and exogenous steroids in pediatric urine and plasma. Ultra-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS) was used to simultaneously quantify steroid hormones in children plasma and urine. Under the optimum conditions, th...
