Introduction
25-Hydroxy Vitamin D, or 25(OH)D, is the primary circulating form of Vitamin D in the human body and is globally recognized as the most reliable biomarker for assessing overall Vitamin D status. It plays a foundational role in bone metabolism by regulating calcium and phosphorus homeostasis, which is essential for healthy bone mineralization and skeletal remodeling.
Clinical Applications
Accurate Diagnosis of Vitamin D Deficiency
Serves as the clinical gold standard for identifying Vitamin D deficiency and insufficiency, enabling early and targeted nutritional or pharmacological interventions.
Osteoporosis & Bone Disease Risk Assessment
Plays a critical role in the risk stratification and auxiliary diagnosis of metabolic bone diseases, including osteoporosis in the elderly, osteomalacia in adults, and rickets in children.
Calcium & Phosphorus Homeostasis Evaluation
Assists clinicians in investigating the root causes of calcium/phosphorus imbalances and secondary hyperparathyroidism, ensuring the essential mineral environment required for maintaining optimal bone density.
Therapeutic Efficacy Monitoring
Provides objective, quantitative data to track a patient's physiological response to Vitamin D supplementation regimens, helping physicians optimize dosages for sustained skeletal health.
