Clinical Significance
Not suitable for assessing vitamin D deficiency in the general population, as levels may remain normal or high even when body stores are low.
The clinical practice guidelines such as the Kidney Disease Outcomes Quality Initiatives (KDOQI), and the Kidney Disease: Improving Global Outcomes (KDIGO) recommend activated vitamin D therapeutic regimens for chronic kidney disease (CKD) patients. Consequently, the measurement of 1,25 (OH)2 D is rapidly becoming an efficient tool in the research of diseases and conditions that affect the normal metabolism of phosphorus and calcium.
