The Vitamin D 25-Hydroxy Deficiency Profile measures this specific metabolite to assess overall vitamin D status.
About Vitamin D 25-Hydroxy Deficiency Test in Reading
Understanding what this test measures and why it is used can help contextualize the results.
The Vitamin D 25-Hydroxy Deficiency Profile quantifies calcidiol, the storage form of vitamin D that reflects both dietary intake and endogenous synthesis. Because calcidiol has a relatively long half-life, it is considered the most reliable indicator of vitamin D adequacy.
Vitamin D plays essential roles in calcium absorption, bone mineralization, and immune function. A deficiency in 25-hydroxyvitamin D can impair these processes, potentially leading to bone pain, muscle weakness, or increased susceptibility to certain conditions over time.
This test is typically ordered when a clinician suspects insufficient vitamin D intake, malabsorption, or inadequate sun exposure. Results are reported as a concentration, and interpretation should always be made by a qualified healthcare professional in the context of the individual's health history.
