1, 25-DI HYDROXY CHOLECALCIFEROL (VITAMIN D3)
Standard 25-hydroxyvitamin D test: Measures the inactive, storage form of vitamin D. This is the most common test used to determine overall vitamin D sufficiency or deficiency.
1, 25-dihydroxyvitamin D (calcitriol) test: Measures the active form of vitamin D, which has a very short lifespan in the blood. Because of this, it is not an accurate way to determine your body's overall vitamin D stores.
