Its serum concentration is used clinically to assess vitamin D status. 25 (OH)D 2 (derived from vitamin D 2) has a lower affinity than 25 (OH)D 3 for DBP and, therefore, has a shorter half-life in circulation. Most assays measure 25 (OH)D 2 and 25 (OH)D 3 (hereafter referred to simply as 25 (OH)D). 25 (OH)D has a biological half-life of 2–3 weeks.
