About this treatment
The Vitamin D test evaluates the concentration of 25‑hydroxy vitamin D (25‑OHD) from a standard venous blood draw. Vitamin D plays a role in calcium absorption, bone remodeling, and may support immune system balance, so knowing your level can guide lifestyle or supplement decisions. This test is suited for adults concerned about bone health, those with limited sunlight, or anyone taking vitamin D supplements who wants to verify adequacy. The laboratory processes the sample and delivers results within 24‑48 hours. Included with the price are the venous blood collection, laboratory analysis of the single vitamin D marker, and a detailed results report with a brief tele‑consultation to discuss the findings. No fasting is required.
