Order Vitamin D 25-Hydroxy Deficiency TestVitamin D is a fat-soluble nutrient that supports calcium absorption, bone health, and normal immune function. Because it arrives through sunlight, food, and drinks, intake varies widely from person to person. This blood test measures 25-hydroxyvitamin D, also called calcidiol, the main circulating form of vitamin D and the standard marker used to assess vitamin D status.
About Vitamin D 25-Hydroxy Deficiency Test in Normal
The Vitamin D 25-Hydroxy Deficiency Test evaluates the body's vitamin D reserve by measuring calcidiol in the blood.
Vitamin D obtained from sunlight, food, and drinks is converted by the liver into 25-hydroxyvitamin D, or calcidiol. This form circulates in the bloodstream and serves as the best general indicator of vitamin D supply.
A 25-hydroxyvitamin D measurement helps identify a deficiency or insufficiency, which can occur when sun exposure is limited, dietary intake is low, or absorption is reduced. The result is a single number that reflects the body's overall vitamin D status rather than a snapshot of recent intake.
Results are typically available within one to three business days. Preparation instructions should be followed as provided by the laboratory performing the collection.
