About Vitamin D 25-Hydroxy Deficiency Test in Gresham
The Vitamin D 25-Hydroxy Deficiency Test evaluates circulating levels of calcidiol, the primary storage form of vitamin D.
Vitamin D plays a role in calcium and phosphate regulation, which supports bone health, muscle function, and immune activity. The 25-hydroxy form is considered the best indicator of overall vitamin D status because it reflects both dietary intake and sunlight exposure.
Blood is collected and analyzed to determine the concentration of 25-hydroxyvitamin D. Results are typically reported as nanograms per milliliter (ng/mL) or nanomoles per liter (nmol/L). Reference ranges may vary by laboratory, but low levels generally indicate insufficient or deficient vitamin D.
Factors that can influence vitamin D levels include limited sun exposure, darker skin pigmentation, older age, certain medical conditions, and the use of specific medications. This test is often ordered when a deficiency is suspected or when monitoring is needed.
