WebThis primary circulating form of vitamin D is biologically inactive with levels approximately 1000‑fold greater than the circulating 1,25‑dihydroxyvitamin D. The half life of circulating vitamin D (25‑OH) is 2‑3 weeks. Most of the vitamin D (25‑OH), measurable in serum, is vitamin D 3 (25‑OH) whereas vitamin D 2 (25‑OH) reaches ... WebConsequently, Vitamin D 25-hydroxy is the preferred initial test for assessing vitamin D status. However, in the presence of renal disease, 1,25-dihydroxy vitamin D levels may be needed to adequately assess vitamin D status.

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 ... driving school anderson sc
