Siemens offers new standardized Vitamin D Total assay
Healthcare News | 2014-08-11
Siemens is pleased to announce the availability of our standardized ADVIA Centaur® Vitamin D Total assay to align with the ID-LC/MS/MS 25(OH)vitamin D Reference Measurement Procedure (RMP)1,2. The RMP is a reference procedure of the National Institutes of Health's Office of Dietary Supplements' Vitamin D Standardization Program (VDSP), an initiative to standardize 25(OH)vitamin D measurement across methods and manufacturers.
The ADVIA Centaur Vitamin D assay is also a certified procedure of the Centers for Disease Control (CDC) Vitamin D Standardization-Certification Program (VDSCP)3, a program to improve diagnosis, treatment, and prevention of diseases by standardizing clinical laboratory measurements.
The revised ADVIA Centaur Vitamin D Total assay will enhance accuracy and reliability, providing clinicians and patients with a clear understanding of their results.
Vitamin D Deficiency
Globally, over 1 billion people are vitamin D deficient1, and deficiency rates have increased as people have limited their sun exposure due to the risk of skin cancer. Vitamin D deficiency has long been associated with rickets in children and osteomalacia in adults, and long-term insufficiency of calcium and vitamin D leads to osteoporosis. However, in recent years, vitamin D has become an indicator of general health status, and there have been multiple publications linking vitamin D deficiency to several disease states, such as cancer, cardiovascular, diabetes, and autoimmune diseases2. This, in turn, has led to more commercially available automated vitamin D assays. However, since there has not been a universal vitamin D standard, different vitamin D assays and methods produced varying results, raising the need for standardization among manufacturers and assays. Vitamin D standardization is necessary to create the anchor vitamin D values need.
