应用
- 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).
