Siemens receives FDA clearance for re-standardized Vitamin D Total assay

Aug 08, 2014

The FDA has cleared the Siemens Healthcare Diagnostics re-standardized ADVIA Centaur Vitamin D Total assay1, which has also recently become a certified procedure of the Centers for Disease Control (CDC) Vitamin D Standardization Certification Program (VDSCP)2. The Siemens assay, which the company voluntarily re-standardized to align with a reference measurement procedure used in the Vitamin D Standardization Program (VDSP) for vitamin D measurement3, is the first such assay to receive FDA clearance. The re-standardized assay enhances accuracy and reliability in vitamin D testing and enables clinicians to generate reproducible and comparable results.


The recent increased demand for vitamin D testing has led to more commercially available vitamin D assays. However, without a universal vitamin D standard, different assays and testing methods produced varying results. In an effort to standardize the laboratory measurement of vitamin D status measurement worldwide, the National Institutes of Health’s Office of Dietary Supplements (NIH ODS) introduced the VDSP in 2010.


The re-standardized ADVIA Centaur Vitamin D Total assay is also now available with pediatric observed values for ages 12 months to up to 21 years old. Studies have shown that vitamin D deficiency in children is widespread, and can lead to such issues as skeletal deformities, brittle bones, frequent fractures and even premature osteoporosis later in life4.
