Individual tests

Our bones are continually being remodeled in a two-step process: the “breakdown” of bone (resorption) and the replacement of the removed bone (formation). In osteoporosis, the bones are weakened because the breakdown occurs faster than the rebuilding. When bone is resorbed, fragments of the bone collagen are released into the bloodstream. One of these fragments is called “C-telopeptide.” This test helps assess the loss of bone mass in cases of osteoporosis or other bone diseases such as Paget’s disease.
