the 25-hydroxy vitamin D (calcidiol) blood test is used to determine how much vitamin D is in the body.[4] The blood concentration of calcidiol is considered the best indicator of vitamin D status.[5] It is the most sensitive measure,[6] though experts have called for improved standardization and reproducibility across different laboratories.[5] According to MedlinePlus the normal range of calcidiol is 30.0 to 74.0 ng/mL.[4] The normal range varies widely depending on several factors, including age and geographic location. A broad reference range of 20�C150 nmol/L has also been suggested,[7] while other studies have defined levels below 80 nmol/L as indicative of vitamin D deficiency.[8]
