Biological Variation of Adrenal-Related Endocrine Biomarkers Used for Investigation of Secondary Hypertension.
BACKGROUND Adrenal-related biomarkers are central in evaluating endocrine causes of secondary hypertension, but their interpretation is influenced by biological variation (BV). In this study, we aimed to estimate the within-subject (CVI) and between-subject (CVG) BV and derive the reference change values (RCVs), the In...
