Several vitamin D metabolites circulate in the blood, but measurement of serum levels of 25-hydroxyvitamin D [25-(OH)D] is a standard method to assess vitamin D status. Hypervitaminosis D usually occurs as a result of excessive intake of vitamin D preparations and can lead to hypercalcemia, hypercalciuria, hyperphosphatemia, and low parathyroid hormone levels.Case Report: A primary care physician referred a 26-year-old asymptomatic white woman to our endocrinology clinic because of high serum 25-(OH)D levels (>339 nmol/L [reference range, 75 to 185 nmol/L]) discovered ...References1.
