Description: Calcitriol is the active form of Vitamin D, made in the kidney. It is not the same as Vitamin D, 25-Hydroxy (typically used to measure vitamin D stores), which must be ordered separately.

Turnaround time: Expected turnaround is within 2-4 business days, although this may vary depending on other tests ordered for the same blood draw, and expected variation with testing.
