The Vitamin D 25‑OH test measures the level of 25‑hydroxyvitamin D in a venous blood sample. This single biomarker tells you whether your vitamin D stores are sufficient, which may support bone health, immune function, and mood. It’s ideal for adults who want to check their vitamin D status after limited sun exposure or supplementation.
About this treatment
The Vitamin D 25‑OH test quantifies the concentration of 25‑hydroxyvitamin D (the main circulating form of vitamin D) from a single venous blood draw. Because vitamin D influences calcium absorption, bone remodeling, and immune modulation, the result may help you understand if you have enough of this nutrient to support skeletal strength, seasonal mood changes, or overall wellbeing. The test is suited for people with limited outdoor time, those on vitamin D supplements, or anyone experiencing unexplained fatigue. Results are processed in the laboratory and returned within the standard turnaround time. The price includes the blood draw, laboratory analysis of the vitamin D marker, and a detailed report with a brief tele‑consultation to discuss the findings.
