Vitamin D is a kind of fat-soluble ring-opening sterol, which has anti-rachitic effect. The main physiological role of vitamin D and its metabolites is to maintain normal blood calcium and phosphorus levels, to ensure bone health and normal neuromuscular function. 25-Hydroxy Vitamin D is the main storage form of vitamin D in the human body, and the detection of serum 25-Hydroxy VD level has been recognized as the most reasonable indicator to reflect the status of vitamin D. The measurement of 25-Hydroxy VD can determine the overall vitamin D status, evaluate calcium absorption levels, better...
