Objectives: To compare the levels of E2 in girls measured by LC-MS/MS and CLIA, and to evaluate the correlations between E2 levels and bone age, uterine length, and uterine volume.Methods: 133 newly diagnosed girls were selected. There were 80 girls in the ICPP group (44 in the Tanner II stage in the ICPP group, 36 in the Tanner III in the ICPP group), and 53 in the PT group， 40 healthy girls in the Tanner III gro...

Objectives: To compare the levels of estradiol (E2) in girls measured by liquid chromatography tandem-mass spectrometry (LC-MS/MS) and chemiluminescence immunoassay (CLIA), and to evaluate the correlations between E2 levels measured by the two methods and bone age, uterine length, and uterine volume. To explore the difference, consistency, and accuracy of LC-MS/MS and CLIA in determining E2 in girls with idiopathic central precocious puberty (ICPP), premature ...
