Analytical Chemistry

Clinical significance

This test is used to detect vitamin D deficiency or poisoning (due to excessive intake). Deficiency results in rickets in children and osteomalacia in adults, and from insufficient exposure to sunlight or an inadequate diet. The levels of 25(OH)D3 give a measure of overall reserves, dietary intake and endogenous sunlight-dependent synthesis. 1.25(OH)2D3 is a metabolite of vitamin D and measuring its levels is useful in investigating disorders which might be related to vitamin D metabolism.
