Order Vitamin D 25-Hydroxy Deficiency TestVitamin D is a fat-soluble nutrient that the body obtains through sun exposure, certain foods, and supplements, then converts into measurable circulating forms. The Vitamin D 25-Hydroxy Deficiency Screen evaluates the level of 25-hydroxyvitamin D, also called calcidiol, which is the primary storage form of vitamin D in the bloodstream. Because this form reflects both dietary intake and endogenous synthesis, it is widely used to assess vitamin D status.
About Vitamin D 25-Hydroxy Deficiency Test in Duluth
The 25-hydroxyvitamin D blood test is the standard laboratory method for evaluating vitamin D sufficiency.
Vitamin D exists in several forms, but 25-hydroxyvitamin D is considered the best indicator of overall vitamin D status because it circulates longer and at higher concentrations than the active hormone form. The test measures this metabolite to determine whether a person has adequate, insufficient, or deficient levels.
Deficiency in vitamin D can occur when sun exposure is limited, dietary intake is low, or the body's absorption or conversion processes are impaired. Because symptoms of low vitamin D are often nonspecific or absent, laboratory testing provides objective information that history and physical examination alone cannot supply.
The test requires a blood sample, typically collected from a vein in the arm. Results are reported as a numerical concentration, and interpretation depends on the reference range used by the performing laboratory. Healthcare providers use these results alongside clinical context to determine whether further evaluation or management is appropriate.
