Most vitamin D is converted to 25(OH)D in the serum, giving an accurate picture of vitamin D status.

[53] The levels of 1,25(OH)D can remain normal even when a ...

The first of these (also ...

A third important effect of PTH on the kidneys is stimulation of the conversion of 25-hydroxy vitamin D into 1,25-dihydroxy vitamin D (calcitriol). [216] This form of vitamin D is the active hormone which promotes calcium uptake from the intestine via the action of calbindin. [218] Calcitriol also reduces calcium loss to urine. [215]
