Standardisation of Vitamin D assay

Siemens Healthcare Diagnostics has become the first manufacturer to gain standardisation of its ADVIA Centaur Vitamin D Total assay to the National Institute of Standards and Technology - Ghent University Reference Measurement Procedure based on isotope-dilution liquid chromatography-tandem mass spectrometry.

The Vitamin D Standardisation Programme (VDSP) was established in 2010 and stated that all manufacturers of Vitamin D assays need to demonstrate alignment. Siemens is now leading the initiative to achieve standardisation alignment of 25 (OH) Vitamin D measurements across methods and manufacturers.

The Siemens ADVIA Centaur Vitamin D Total assay provides confidence in results through alignment with the VDSP, also offering an equimolar vitamin D response and minimal cross-reactivity with 3-epi-25-OH Vitamin D3 (1.1 per cent). Results are available in 18 minutes, providing clinicians and patients with fast, accurate results and allowing laboratories to be better prepared to meet current and future demands.

“Testing for Vitamin D has traditionally been a complicated process, having to understand the different clinical and analytical factors that impact results,” states Allan Thompson, Immunoassay Product Manager at Siemens Healthcare Diagnostics. “With this latest standardisation, Vitamin D testing is within reach of any size laboratory and users of the ADVIA Centaur Vitamin D Total assay can have confidence in consistent and accurate results.”

The Vitamin D Standardisation Programme (VDSP) was established in 2010 by the US National Institutes of Health’s Office of Dietary Supplements, in collaboration with the Centers for Disease Control and Prevention’s National Centre for Environmental Health, National Institute of Standards and Technology and Ghent University.
