There are two basic forms of vitamin D: <strong>vitamin D3<\/strong>, or cholecalciferol, which is produced in our skin, and <strong>vitamin D2<\/strong>, or ergocalciferol, which we cannot produce ourselves but intake through food or as a supplement.<\/p>\n<p>In the human body, both forms of vitamin D undergo transformations. They are first converted into 25OH vitamin D, and then into 1,25OH vitamin D. 25OH vitamin D is the main form of vitamin D in our blood, but it is biologically inactive. From this form, the active hormone 1,25-dihydroxyvitamin D is produced. Due to its long half-life and higher concentration in the blood, <em>the level of 25OH D is usually measured to assess and monitor a person&#8217;s vitamin D status.<\/em><\/p>\n<p>Vitamin D plays a crucial role in the health of our bodies. <strong>It is essential for the proper growth and development of bones and other tissues.<\/strong> It also participates in the regulation of calcium, phosphate, and, to a lesser extent, magnesium metabolism. Additionally, vitamin D is important in regulating our immune system.<\/p>\n<h2>Why is a vitamin D blood test done?<\/h2>\n<p>A blood test for vitamin D is recommended for individuals with elevated or decreased levels of calcium, phosphate, and\/or parathyroid hormone (PTH). It is also recommended for those with symptoms of bone disease. The test is indicated for individuals at risk of vitamin D deficiency, such as those on long-term anticonvulsant therapy or those suspected of having a vitamin D deficiency. Periodic testing is also important to assess the response to therapy in individuals diagnosed with a vitamin D deficiency.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>The total vitamin D analysis, conducted via a blood test, is essential for making a differential diagnosis for conditions such as rickets and osteomalacia.
