Siemens offers calcium measurement on all of its clinical chemistry and integrated systems, including the ADVIA® Chemistry, Dimension® and Dimension Vista® systems.



  • Enhances calcium absorption in the intestines by stimulating the renal synthesis of 1,25(OH)2vitamin D
  • Increases the amount of calcium in the blood through the release of PTH and the removal of calcium from the bone
  • Decreases the amount of calcium by releasing less PTH

Vitamin D

  • Helps to form and maintain strong and healthy bones by increasing the amount of dietary calcium absorbed by the intestines
  • Stops the parathyroid gland from secreting parathyroid hormone, which would increase levels of calcium in the blood
  • Protects against osteoporosis, cancer, and hypertension


  • Protein that binds to calcium; it is manufactured by the osteoblasts in bone and dentin
  • A highly specific marker of late stage osteoblastic activity
  • Higher serum-osteocalcin levels are relatively well correlated with increases in bone mineral density


  • Excreted in urine and is a specific marker of bone resorption and osteoclastic activity.
  • Used along with other bone markers to diagnose bone diseases such as osteoporosis, bone metastatis, and Paget's disease
  • Useful in monitoring treatments that contain bone-active agents such as estrogens and bisphosphonates.
