What is 25-Hydroxyvitamin D (Genova)?

25-Hydroxyvitamin D (Genova)’s main role is that is helps to regulate the amount of calcium and phosphate in the body. These nutrients are needed to keep bones, teeth, and muscles healthy. When the weather is sunny, we are able to get most of the vitamin D we need from sunlight on our skin. Our other main source of vitamin D is from our diet. Foods such as oily fish, red meat, liver, egg yolk, and fortified grains are rich with it. The most accurate way to measure how much vitamin D is in your body is the 25-hydroxy vitamin D blood test. A healthcare professional may order this test if a person is at risk of having vitamin D deficiency, including:

  • People who don’t get much exposure to the sun
  • Older adults
  • People who are obese
  • Babies who are breastfed only (formula is usually fortified)
  • People who have had gastric bypass surgery
  • People with malabsorption disorders (e.g., Crohn’s disease)

A healthy result should fall into the range 50 – 80 ng/mL.
