I am posting here because I would like the answer in the non-logged in part. I have searched and cannot find the name of the Vitamin D test to order. I know it has been asked/answered here numeros times. Could someone clarify? Also, what is calcidol?

Hi, Laurel. The test is called 25-hydroxy vitamin D test

About calcidiol:

Calcifediol (INN), also known as calcidiol, 25-hydroxycholecalciferol, or 25-hydroxyvitamin D (abbreviated 25(OH)D), is a prehormone which is produced by hydroxylation of vitamin D3 (cholecalciferol) in the liver. 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.[1][2]
