Variability of vitamin D results remains a hot topic today as more options are available to laboratories. This webinar examines how clinical and analytical factors such as vitamin D binding protein (DBP), 3-epi-25(OH)vitamin D3, and vitamin D2 supplementation may impact vitamin D values, and how these in turn may impact clinical decisions. It also discusses how initiatives such as the NIH Office of Dietary Supplements Vitamin D Standardization Program (VDSP) will improve standardization of results.

Learning objectives:
Understand the clinical and analytical factors that influence the measurement of vitamin D by immunoassay and how they impact patient results.
Learn about the implementation of the Vitamin D Standardization Program and the next steps in vitamin D harmonization.
