Vitamin D is a precursor of the steroid hormone calcitriol that is crucial for bone and mineral metabolism. Both the high prevalence of vitamin D deficiency in the general population and the identification of the vitamin D receptor in the heart and blood vessels raised interest in the potential ...
Values of 20 nmol/L were considered severe, 20.1 - 37.5 nmol/L moderate, 37.6 - 50 nmol/L mild deficiency, and 25 (OH) vitamin D3 levels higher than 50 nmol/L were considered normal.Results: The results showed 59.6% of students suffered from vitamin D deficiency (14.4% severe, 24.4%...
At a time of increasing concern about low vitamin D levels in the world's population and increased use of blood tests for the vitamin, scientists are reporting development of a much-needed reference material to assure that measurements of vitamin D levels are accurate. The repor...
A structured questionnaire was used to measure anxiety, and the lab analysts at the two centres reported the participants' vitamin D levels based on their blood tests. Results: The anxiety mean among Saudis with vitamin D deficiency was higher than among their peers with vitamin D insufficiency....
performed on relatively small sample sizes with differences in methods of vitamin D concentration estimation such as radioimmunoassay, ELISA, chemiluminescence etc. The prevalence of vitamin D deficiency has been also been described using different cut-offs, thus making interpretation of results difficult....
