Newswise — BREA, CALIF. — (January 7, 2015) — Beckman Coulter Diagnostics has received 510(k) clearance from the U.S. Food and Drug Administration (FDA) for the Access 25(OH) Vitamin D Total assay. Offering state-of-the-art performance, the new assay is an important addition to the company’s bone metabolism assay menu and is available for use on its Access 2 and UniCel DxI series of immunoassay systems. "FDA clearance of our 25(OH) Vitamin D Total assay allows us to provide laboratories with the tools needed to confidently diagnose and manage vitamin D deficiency-related diseases," said Arnd Kaldowski, president, Beckman Coulter Diagnostics. "The new assay delivers increased accuracy in patient results through traceability to the gold standard 25(OH) vitamin D reference measurement procedure (RMP) from Ghent University and equimolar detection of 25(OH) vitamin D2 and 25(OH) vitamin D3."

The Ghent RMP is the reference procedure utilized by the Vitamin D Standardization Program (VDSP), an international collaboration established by the Office of Dietary Supplements at the National Institutes of Health, with the goal of promoting standardized laboratory measurements of 25(OH) vitamin D around the world. "Alignment with this internationally recognized reference measurement procedure provides increased confidence that patients will be correctly assessed for vitamin D deficiency or insufficiency," said Michael Samoszuk, MD, chief medical officer, Beckman Coulter Diagnostics.

The new assay also provides excellent stability, greater ease-of-use and convenient storage through innovative new packaging designed to prevent light-induced reagent degradation. Laboratories will also benefit from the speed and flexibility provided by the company’s numerous instrumentation options, including the UniCel DxI 800, the industry’s highest throughput immunoassay analyzer.
