In this study, ultra performance liquid chromatography-tandem mass spectrometry (UPLC-MS\/MS) was used to detect serum bile acid spectrum in IM children quantitatively, and to investigate its role in the early assessment of hepatic injury.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Methods<\/jats:title>\n                    <jats:p>This case-control study was conducted at Yuhuan People's Hospital.
