How soon after a change is made in calcium or vitamin D dosing should PTH values change?
Changes in PTH occur within minutes after calcium changes in the blood. However, changes in the bone morphology resulting from changes in PTH require 3-6 months. This is the advantage of measuring PTH more frequently since changes in bone morphology can be controlled before they occur by controlling PTH secretion.
