Vitamin D was first described in the 20th century when a cause for the high prevalence of rickets was sought. With the fortification of certain foods with vitamin D, the prevalence of rickets decreased and little attention was placed on vitamin D. However, in the past decade there has been a revived interest in vitamin D, as it is thought to be associated with various nonskeletal disorders. Research has found that the prevalence of vitamin D deficiency worldwide is actually much higher than thought, and this has led to a massive increase in the demand for laboratory testing of vitamin D levels.
