Warnex Receives DEQAS Certification for Vitamin D Testing

NEW YORK (GenomeWeb News) – Warnex today announced its Bioanalytical Services division participated in the International External Quality Assessment Scheme, or DEQAS, and received DEQAS certification for the analysis of Vitamin D (25-hydroxyvitamin D.)

Analysis of 25-hydroxyvitamin D is one of the most accurate testing methods of Vitamin D in the body, Warnex said, and its participation in DEQAS demonstrated the reliability of its method in terms of absolute values, assay linearity, and assay precision. Warnex's method of analysis combines high-performance liquid chromatography and mass spectrometry to measure 25-hydroxyvitamin D2 and D3 in plasma.

Vitamin D deficiency has been linked to rickets in children and osteomalacia and osteoporosis in adults, as well as certain cancers, type 1 diabetes, Alzheimer's, and other illnesses.
