Written by: Staff

Vitamin D is essential to our bone health and it has been proven to help prevent rickets and osteomalacia.  Previous research studies have also shown those who lack vitamin D are also prone to other serious diseases such cancer and heart diseases, prompting doctors to order vitamin D tests to see your levels.

For this reason, individuals who are considered to be a high risk for vitamin D deficiency may often be asked to take a vitamin D blood test, especially if suffering from osteoporosis, osteomalacia or a syndrome which keeps them from absorbing enough vitamin D, but some skeptics state 90 percent of the time, the test isn’t necessary.
