Waters Corporation (NYSE:WAT) announced today that its fully-validated Waters® MassTrak™ Vitamin D Solution is now CE-marked in accordance with IVD Directive 98/79/EC for the quantitative measurement of 25(OH) D 2 and D 3 (25-OH-VitD) from human plasma and serum. The IVD LC-MS/MS system solution is a complete solution consisting of reagents and consumables, instrumentation, and software and support services for clinical laboratories routinely measuring vitamin D in patient samples* . The Vitamin D solution is currently only available for sale in Europe.

"Our MassTrak Vitamin D Solution is the first, CE-marked, single-vendor system to measure both vitamins 25(OH) D 2 and D 3 independently and accurately from human plasma and serum in a single analysis," said Jose Castro-Perez, Ph.D., Director of Health Sciences, Global Marketing Operations, Waters Corporation. "It's the ideal solution for clinical laboratories performing (25-OH-VitD) analysis on a routine basis and which may want to standardize (25-OH-VitD) analysis on a single-vendor platform."

Vitamin D, the main source of which is from dietary intake, is part of a family of fat-soluble secosteroids and has two major forms - ergocalciferol (plant derived Vitamin D 2) and cholecalciferol (animal derived Vitamin D 3). Vitamin D is also derived from the conversion of 7-dihydrocholesterol to Vitamin D 3 following exposure of skin to sunlight. Increasingly, research is revealing the importance of vitamin D in protecting against a host of health problems. In the absence of vitamin D, bones can become brittle and thin. The research also suggests that vitamin D plays a role in modulating cell growth, the function of neuromuscular and immune systems, and reducing inflammation. It also indicates that those most at risk of a vitamin D deficiency are those who shun the sun, have milk allergies, adhere to a strict vegan diet, or suffer from certain diseases.

Due, in part, to mounting evidence of the importance of vitamin D to human health and to news media coverage, Medicare reimbursement volumes of vitamin D laboratory tests rose 83-fold from 2000 - 2010 1.

The MassTrak Vitamin D Solution is configured with the Waters ACQUITY UPLC® I-Class/ Xevo® TQD IVD System, the MassTrak Vitamin D Kit and MassLynx ® (IVD) Mass Spectrometry Software. The MassTrak Vitamin D Kit provides metrological traceability to the National Institute of Standards and Technology (NIST) Standard Reference Material (SRM) 2972, enabling standardization and lot- to-lot consistency for an easy comparison of results from multiple laboratories. For high-volume vitamin D testing, the system is designed for use with an automated liquid handler and custom pipetting script provided with the kit.

LC-MS/MS in the Clinical Laboratory

In pursuit of better accuracy and precision for clinical laboratory analyses, liquid chromatography tandem mass spectrometry (LC-MS/MS) is rapidly becoming the analytical technique of choice. Waters IVD LC-MS/MS medical devices provide clinical laboratories access to technologies delivering selectivity, sensitivity and versatility - performance characteristics that traditional methods, such as immunoassays, often struggle to meet.

Designed to optimize workflow from pre-analytics to post-analytics, our system portfolio offers a wide variety of options for the routine use of LC-MS/MS in the clinical laboratory.
