Vitamin D Test

The Vitamin D test is a serum or dried blood spot investigation that quantities 2-5-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 greatest indication of a patient's authentic vitamin status. The major biologic function of Vitamin D is to preserve the ordinary blood levels of calcium and phosphorus associated with bone mineralization. Vitamin D additionally affects expression of more than 2,000 genes, including those responsible for regulation of cellular proliferation, apoptosis differentiation, cell, and angiogenesis.

Vitamin D insufficiency was linked to increased risk for several common and severe diseases, including osteoporosis, diabetes, CVD, and some common cancers. Insufficiency is, in addition, prevalent in babies who tend not to receive Vitamin D supplementation and who are exclusively breastfed. Adults of ages who have darker skin (increased skin melanin) or who always wear sun-protection or limit their outside activities, like homebound aged individuals, are also susceptible to Vitamin D deficits.

Studies imply that exposure to sun light enriches the creation of Vitamin D in your skin and prevents many chronic illnesses. Seasonal melancholy can be linked with low amounts of Vitamin D, notably during the winter months when sun exposure is at the absolute minimum. Vitamin D can also come from supplementation and diet, but there are hardly any foods (fatty fish, fish liver oil, and eggs) that normally contain Vitamin D. Several meals maintain to be fortified with Vitamin D, but the artificial type is not as strong and doesn't last as long in the human anatomy.

The Vitamin D test can help to establish if sun exposure is adequate, if dietary Vitamin D is satisfactory, and to assess the likeliness of mal absorption or liver disease. VDR is expressed by most cells in every organ of the body. More than 2,000 genes are regulated by VDR activation. The main role of Vitamin D is always to regulate blood levels of calcium and phosphorus by promoting absorption in the guts and reabsorption in kidneys.

Phosphorus and calcium levels are important for growth and bone mineralization together with for the prevention of hypocalcemic tetany. Vitamin D is also a significant immune regulator. It boosts phagocytosis, anti tumor action, and immunomodulary features that may play a role in autoimmune disease.
