The Most Common Vitamin Deficiency in the United States.
 
Vitamin D is primarily responsible for maintaining normal levels of calcium and phosphorus in the blood, which are essential for bone mineralization.
 
However, it also has a significant impact on the expression of over 2,000 genes involved in cellular proliferation, differentiation, apoptosis, and angiogenesis.
 
The immune-modulating effects of Vitamin D are profound and its deficiency is associated with many common and serious diseases, including certain cancers, diabetes, cardiovascular disease, and osteoporosis.
 
Vitamin D Test is a useful tool in assessing Vitamin D levels, determining if sun exposure and dietary intake are adequate, and evaluating the likelihood of malabsorption or liver disease.
 
Vitamin D deficiency has been linked to increased risk for many common and serious diseases, including some common cancers, diabetes, cardiovascular disease, and osteoporosis.
 
Deficiency is also prevalent in infants who are solely breastfed and who do not receive Vitamin D supplementation.
 
Adults of all ages who have darker skin (increased skin melanin) or who always wear sun protection or limit their outdoor activities, such as homebound elderly persons, are also prone to Vitamin D deficits.
 
Sunlight exposure is a natural source of Vitamin D and has been shown to prevent many chronic diseases.
 
Low levels of Vitamin D are also linked to seasonal depression, particularly during the winter months with less sunlight exposure.
 
Vitamin D can also be obtained through diet and supplementation, although there are few food sources (fatty fish, fish liver oil, and eggs) that contain it naturally. Fortified foods may contain synthetic forms of Vitamin D, which are less potent and have a shorter lifespan in the body.
 
This Vitamin D Test is a dried blood spot analysis that quantitated:
 
25-hydroxyvitamin D2 metabolites
25-hydroxyvitamin D3 metabolites
 
The metabolite 25-hydroxyvitamin D is the major circulating form of Vitamin D in the body and the best indicator of a patient’s true vitamin status.
 
The major biologic function of Vitamin D is to maintain the normal blood levels of calcium and phosphorus involved in bone mineralization.
 
Vitamin D also influences the expression of more than 2,000 genes, including those responsible for the regulation of cellular proliferation, cell differentiation, apoptosis, and angiogenesis.
 
The immune-modulating effects of Vitamin D are profound, as evidenced by the many conditions that are associated with Vitamin D deficiency.
