Order Vitamin D 25-Hydroxy Deficiency TestVitamin D is a fat-soluble nutrient that the body can obtain from sunlight exposure, certain foods, and dietary supplements. Before it can be used, it undergoes conversion in the liver into 25-hydroxyvitamin D, also called calcidiol. This form circulates in the bloodstream and serves as the primary marker laboratories use to assess vitamin D status. The Vitamin D 25-Hydroxy Deficiency Test measures the concentration of calcidiol in a blood sample to help determine whether a person's vitamin D level falls below the expected range.
About Vitamin D 25-Hydroxy Deficiency Test in Paramount
The Vitamin D 25-Hydroxy Deficiency Test evaluates the body's stored vitamin D by quantifying calcidiol, the main circulating metabolite.
Vitamin D from sunlight, food, and supplements is biologically inactive until it passes through the liver, where it becomes 25-hydroxyvitamin D. This metabolite has a relatively long half-life, which makes it a stable and reliable indicator of overall vitamin D reserves.
A deficiency in vitamin D can develop when sun exposure is limited, dietary intake is low, or the body's absorption and conversion processes are impaired. Because the symptoms of low vitamin D are often subtle or nonspecific, laboratory testing provides objective information that a physical examination alone cannot supply.
Results from this test are reported as a numeric concentration, and healthcare providers interpret that value alongside a person's health history, risk factors, and any symptoms. The test itself involves a routine blood draw, and the lab's instructions should be followed regarding any preparation.
