    Recent studies have shown vitamin D deficiency to be very common in all age groups. Vitamin D and parathyroid hormone (PTH) are important regulators of the bone and mineral homeostasis. 

    This presentation will describe the role of vitamin D and PTH on calcium metabolism and bone health and will also review the metabolism and clinical utility of PTH, 1,25 dihydroxyvitamin D and 25 OH Vitamin D.   The discussion will address how the various laboratory assays are used to diagnose and monitor conditions with abnormal calcium levels.

    Learning Objectives

    • Understand the clinical background of PTH, 1,25 Dihydroxyvitamin D and 25 OH Vitamin D
    • Learn the challenges of testing of PTH and Vitamin D 
    • Describe the actions and programs for Standardization of Vitamin D and PTH assays.
