Cutoff Value for 25 Hydroxy-Vitamin D Which Leading to sYmptomatic Vitamin D Deficiency in Children is 15 ng/mL in a Chemiluminescent Immunoassay

Ogiwara Yasuko , Hachiya Rumi , Shibata Nao , Ishii Akira , Higuchi Shinji , Nagasaki Keisuke , Kamasaki Hotaka , Yorifuji Toru , Hasegawa Yukihiro

Background & Purpose: Vitamin D is essential for bone and calcium metabolism, and a deficiency of this nutrient can lead to rickets and hypocalcemia. A 25 hydroxy-vitamin D (25OHD) value below 12 ng/mL (30 nmol/L) has been established by global consensus on the basis of several studies as constituting vitamin D deficiency. For example, (1) the incidence of nutritional rickets can increase at a 25OHD concentration of less than 12 ng/mL; (2) PTH increases wh...
