Pth calcium homeostasis
WebCalcium and phosphate homeostasis involves interrelated actions of parathyroid hormone (PTH), vitamin D ( the active form of vitamin D is 1,25(OH) 2 D (calcitriol), and calcitonin. These hormones influence calcium and phosphate release from bones (osteolysis) and excretion or resorption from the kidneys or intestines.

WebCalcium homeostasis is also related to oral calcium intake, vitamin D prescription, parathyroid hormone levels, and phosphate levels. Whereas the normal serum ionized calcium level varies from 1.15 to 1.29 mmol/L, the calcium concentration of dialysate (in which all of the calcium is ionized) usually ranges from 1.25 to 1.79 mmol/L.
