Calcidiol is then converted in the kidneys (by the enzyme 25(OH)D-1α-hydroxylase) into calcitriol (1,25-(OH)2D3), a secosteroid hormone that is the active form of vitamin D. It can also be converted into 24-hydroxycalcidiol in the kidneys via 24-hydroxylation.\u003c\/p\u003e\u003cp\u003eIn medicine, blood concentration of calcidiol is considered the best indicator of vitamin D status. It is the most sensitive measure, though experts have called for improved standardization and reproducibility across different laboratories. The normal range varies widely depending on several factors, including age and geographic location. A broad reference range of 20–150 nmol\/L has been suggested, while several studies have defined levels below 80 nmol\/L as indicative of vitamin D deficiency.\u003c\/p\u003e","brand":"Abbkine Scientific Co., Ltd.","offers":[{"title":"48 T","offer_id":53338612105581,"sku":"KTE60833-48T","price":359.0,"currency_code":"USD","in_stock":true},{"title":"96 T","offer_id":53338758349165,"sku":"KTE60833-96T","price":619.0,"currency_code":"USD","in_stock":true},{"title":"96 T×5","offer_id":53338758381933,"sku":"KTE60833-96TX5","price":2809.0,"currency_code":"USD","in_stock":true},{"title":"96 T×50","offer_id":53338758414701,"sku":"KTE60833-96TX50","price":26209.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0949\/7424\/7277\/files\/KTE60833.png?v=1778954700","url":"https:\/\/www.ebiohippo.com\/products\/human-25-hydroxy-vitamin-d3-25-hvd3-elisa-kit-bhe13703049","provider":"BioHippo","version":"1.0","type":"link"}
