Vitamin D Testing


  • Used to determine whether a patient has a Vitamin D deficiency.
  • Is known as the “sunshine vitamin” because Vitamin D is produced by the body in response to sunlight.
  • It is also occurs naturally in a few foods (some fish, fish liver oils, egg yolks and in fortified dairy and grain products).
  • Vitamin D is essential for strong bones because it helps the body use calcium from your diet. Vitamin D deficiency has been associated with rickets (a disease in which the bone tissue doesn’t properly mineralize, leading to soft bones and skeletal deformities).
  • Symptoms such as bone pain and muscle weakness can mean you have a Vitamin D deficiency.
  • Low blood levels of the vitamin have been associated with: increased risk of death from cardiovascular disease, cognitive impairment in older adults and even cancer.
  • Research suggests that Vitamin D could play a role in the prevention and treatment of a number of different conditions, including type1 and type 2 diabetes, hypertension, glucose intolerance and multiple sclerosis.
