Vitamin D Test
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.
MosaicDX’s 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.
MosaicDX provides the Omega-3 Index Complete Test which assesses the fatty acid levels in blood using a dried blood spot for collection. This comprehensive test not only reports the levels of all 24 fatty acids but also includes the Omega-3 index, ratios, and the trans-fat index, providing a holistic analysis of one’s fatty acid status.

Why Assess Vitamin D Levels?
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.
MosaicDX’s Vitamin D Test is a serum or dried blood spot analysis that quantitates 25-hydroxyvitamin D2 and 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 expression of more than 2,000 genes, including those responsible for 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.

In case immediate shipping is not possible, here are some guidelines for specimen stability: Urine samples can be stored in the refrigerator for up to 5 days, and for extended periods in the freezer. This applies to all urine tests performed at MosaicDX, except for the Kryptopyrrole test, for which urine must be frozen immediately and received within 24 hours of collection for accurate results.
