Order Vitamin D 25-Hydroxy Deficiency TestVitamin D is a fat-soluble nutrient that the body can obtain from sunlight exposure, certain foods, and supplements, then convert into a measurable circulating form. The Vitamin D 25-Hydroxy Deficiency Profile assesses that circulating form to help determine whether a person's vitamin D status is adequate, insufficient, or deficient.
About Vitamin D 25-Hydroxy Deficiency Test in Visalia
This profile focuses on 25-hydroxyvitamin D, the main storage form of vitamin D in the bloodstream and the standard marker used to evaluate overall vitamin D status.
Vitamin D begins as either cholecalciferol from sunlight and animal sources or ergocalciferol from plant sources and fortified products. The liver converts these precursors into 25-hydroxyvitamin D, also called calcidiol, which is the form most labs measure because it reflects both dietary intake and sunlight exposure.
Because 25-hydroxyvitamin D has a relatively long half-life, its concentration changes slowly and provides a stable picture of vitamin D reserves. Results are typically reported in nanograms per milliliter or nanomoles per liter, and clinical guidelines define ranges for deficiency, insufficiency, and sufficiency.
Low 25-hydroxyvitamin D levels can occur when sun exposure is limited, dietary intake is low, absorption is impaired, or the kidneys and liver do not convert vitamin D efficiently. Testing this marker helps clinicians interpret symptoms and decide whether further evaluation or monitoring is appropriate.
