Abstract

CONTEXT: Prior reports of plasma estradiol concentrations and their reference ranges in postmenopausal women identified marked variation, in part due to assay method and body mass index (BMI). OBJECTIVE: To develop an international reference range for plasma estradiol in postmenopausal women, to support accurate assessment of concentrations during systemic and local (e.g., vaginal) estradiol therapy, and to improve risk prediction for diseases, including osteoporosis, breast and endometrial cancers. METHODOLOGY: Estradiol concentrations were measured using primarily liquid chromatography-tandem mass spectrometry (LC-MS/MS) assays in five international cohorts of community-dwelling, postmenop..
