This test measures how much vitamin D is in your body. In the kidney 25-hydroxy vitamin D gets converted to its active form, which helps control calcium and phosphate levels in the body. Low levels of vitamin D may be a result of inadequate exposure to sunlight, inadequate vitamin D in diet, liver or kidney disease, problems with food absorption, or use of certain medicines.
Test is performed on a blood sample. No preparation is needed. Inform your doctor about all the medicines, vitamins, nutritional supplements, herbal or ayurvedic preparations, and homeopathic medicines you are taking
