| Recently published in Circulation, it
was found that Vitamin D deficiency can increase one's risk for
heart disease. The researchers concluded "Vitamin
D is associated with incident cardiovascular disease".

Low levels of 25-Hydroxyvitamin D, the
principal circulation storage form of Vitamin D, are present in
as many as one third to one half of otherwise healthy
middle-aged to elderly adults. The Vitamin D sufficiency is
important to calcium homeostasis and in the maintenance of
healthy bone. Deficiency of Vitamin D leads to the mobilization
of calcium from bone, which can lead to
osteoporosis, osteomalacia, and rickets. Vitamin D
deficiency has been linked to increased risk of developing
- Autoimmune Diseases
- Multiple Sclerosis
- Type 1
Diabetes
- Hypertension
- Cardiovascular Disease

ANY LAB TEST NOW offers DiaSorin's
Vitamin D ICMA assay. The cleared DiaSorin Vitamin D assays have
been used in major clinical studies where Vitamin D is measured.
This test measures both Vitamin D2 and Vitamin D3 together and
reports a total 25-Hydroxy Vitamin D.
Vitamin D Levels are reported part of
Micronutrient Test as well. |
| Vitamin D is a fat-soluble vitamin that
is naturally present in very few foods and available as dietary
supplement. It is also produced when UV Rays from sunlight
strike the skin and trigger Vitamin D synthesis. Vitamin D
obtained from Sun exposure, food and supplements is biologically
inert and must undergo chemical modification for activation. The
first occurs in the liver and converts Vitamin D to 25
Hydroxyvitamin D, also known as calcidiol. The second occurs
primarily in the kidney and forms physiologically active
1,25-dihydroxyvitamin D, also known as calcitriol. |
| Vitamin D has many roles in the body
but primarily it is essential for promoting calcium absorption
in the gut and maintaining adequate serum calcium and phosphate
concentrations to enable normal mineralization of bone and
prevent hypocalcemic tetany. It is also needed for bone growth
and bone remodeling by osteoblasts and osteolasts. |
| There two sources of Vitamin D; diet
and exposure to sunlight. Vitamin D levels can be increased by
spending some time in the sun.
The normal diet is very low in Vitamin D. Most foods, with the
exception of fatty fish oils, contain little Vitamin D. Vitamin
D is available without prescription. |
