Description générale

This Standard Reference Material (SRM) is intended primarily for use in calibration of instruments and techniques used for the determination of these vitamin D metabolites. A unit consists of twenty, two-milliliter ampoules, of four separate ethanolic solutions of vitamin D metabolites, five ampoules of each solution. Each two-milliliter ampoule contains approximately 1.2 mL of solution. The four separate ethanolic solutions of vitamin D metabolites are described below. For more information, please refer to theSDS andCOA.

Application


  • Advanced Calibration for Vitamin D Analysis: The use of 25-Hydroxyvitamin D calibration solutions is pivotal in the development of a candidate reference method for the determination of vitamin D levels from dried blood spot samples. This method offers significant advantages in clinical settings, providing reliable and accurate assessment of vitamin D status which is crucial for diagnosing and managing conditions related to vitamin D deficiency. The research conducted by Zakaria et al. (2020) introduces a standardized approach that enhances the consistency of vitamin D measurements across various laboratories, ensuring high-quality diagnostic information (Zakaria et al., 2020).
