Beckman Coulter’s new ACCESS 25(OH) VITAMIN D TOTAL ASSAY provides laboratories with the tools needed to confidently diagnose vitamin D deficiency or insufficiency. Laboratories will benefit with (1) confidence in patient results through standardization to the gold standard 25(OH) Vitamin D Reference Measurement Procedure (RMP) from Ghent University; (2) accurate clinical assessment of vitamin D status provided by measurement of total 25(OH) vitamin D with equimolar measurement of 25(OH) vitamin D2 and 25(OH) vitamin D3; (3) excellent stability and reproducibility with greater storage convenience from an opaque reagent pack designed to prevent light-induced reagent degradation and (4) optimal productivity for both low and high-volume laboratories using the UniCel DxI and Access 2 Immunoassay Systems.

Bio-Rad’s Liquichek and Lyphochek Specialty Immunoassay Controls are formulated control materials that can provide values for 25-OH Vitamin D2, D3, and Total Vitamin D. Both controls can be used on major automated instruments, as well as LC/MS methods. Long shelf life and open-vial stability allows users to monitor assay performance across multiple reagent lots as well as effective utilization of the control material.

The DiaSorin LIAISON 25 OH Vitamin D TOTAL Assay is a fully automated assay measuring both D2 and D3 for a total result. DiaSorin Vitamin D assays have been used for major national studies such as the Nurse Health Study (NHANES), and have been utilized in clinical studies worldwide. The LIAISON 25 OH Vitamin D TOTAL Assay is certified with the Vitamin D Standardization Program (VDSP). The DiaSorin Assay met the VDSP requirements and no adjustments to the assay or its calibrations were needed. The VDSP is a collaborative initiative organized by the Office of Dietary Supplements of the NIH to help standardize 25 OH Vitamin D measurements across methods. To ensure accurate measurement, all Vitamin D assays should be standardized.
The new LIAISON XL 1,25 Dihydroxyvitamin D assay is an extraction-free, fully automated 1,25 dihydroxyvitamin D assay. The LIAISON XL 1,25 Dihydroxyvitamin D assay eliminates the extraction step, providing higher throughput and a faster time-to-first result of only 65 minutes. The assay is a chemiluminescent immunoassay for the quantitative determination of 1,25 dihydroxyvitamin D in serum and offers excellent precision, accuracy and sensitivity. It will allow laboratories with LIAISON XL Analyzers to run the LIAISON 25 OH Vitamin D TOTAL Assay, LIAISONN-TACT PTH Gen II and LIAISON XL 1,25 Dihydroxyvitamin D together on one instrument utilizing a single serum sample tube.

Siemens ADVIA Centaur Vitamin D Total Assay
The ADVIA Centaur Vitamin D Total Assay from Siemens Healthcare Diagnostics is a fully equimolar, automated total 25(OH) vitamin D (~100% D2 and D3) assay employing a proprietary monoclonal with minimal 1.1% 3-epi-25(OH) vitamin D3 cross-reactivity aligned to the ID-LC/MS/MS 25(OH) vitamin D Reference Measurement Procedure (RMP), the reference procedure for the Vitamin D Standardization Program (VDSP). This assay can be combined with routine, stat, and specialty assays without compromising time. Results are provided in as little as 18 minutes with a throughput of 240 tests per hour. Laboratories can meet increased testing demands by consolidating vitamin D testing on a fully automated, high-throughput immunoassay system.
