Mapping of several bone diseases onto levels of vitamin D (calcidiol) in the blood [6] Normal bone vs. osteoporosis. Vitamin D deficiency is typically diagnosed by measuring the concentration of the 25-hydroxyvitamin D in the blood, which is the most accurate measure of stores of vitamin D in the body.
In patients with secondary hyperparathyroidism, the high PTH levels are an appropriate response to low calcium and treatment must be directed at the underlying cause of this (usually vitamin D deficiency or chronic kidney failure).
The most specific screening test for vitamin D deficiency in otherwise healthy individuals is a serum 25(OH)D level. [11] Less common causes of osteomalacia can include hereditary deficiencies of vitamin D or phosphate (which would typically be identified in childhood) or malignancy.

Vitamin D deficiency: Usually asymptomatic, causes reduce bone density (osteomalacia), rickets, myopathy, and is associated with the development of schizophrenia. It is typically diagnosed by measuring the concentration of the 25-hydroxyvitamin D (25(OH)D) in plasma, which is the most accurate measure of stores of vitamin D in the body ...
Hypovitaminosis D has been associated with many neurological conditions. However, an actual mechanism of action for each of the conditions has yet to be solidified. Many researchers have questioned whether the depletion of vitamin D actually causes these disorders or if vitamin D deficiency is a symptom of these disorders. [medical citation needed]
