Brief Report: Does PTH Increase With Age, Independent of 25-Hydroxyvitamin D, Phosphate, Renal Function, and Ionized Calcium?

Abstract

PTH concentrations increase with age, independent of 25-hydroxyvitamin D, ionized calcium, phosphate, and renal function. Further research is required to explore the underlying mechanisms and clinical relevance and to determine whether the use of age-related PTH reference ranges improves diagnostic accuracy, particularly in elderly individuals.
