Bone markers are blood and urine tests used as an aid in monitoring bone loss in individuals with osteopenia and postmenopausal women on bio identical hormone replacement therapies (BHRT) and bisphosphonate therapies.
Bone is made up largely of type-I collagen, a protein network that gives the bone its strength and framework, and calcium phosphate, a mineralized complex that hardens the bone.
Throughout a person’s lifetime, old bone is constantly being removed (resorption) and replaced with new bone (formation) to maintain a healthy bone structure.
The NTx test is a blood test that measures the concentration of cross-linked N-telopeptides of type I collagen. Levels of NTx correlate with the rate of bone resorption. Bone resorption rates exceeding bone formation result in a net loss of bone and ultimately osteopenia or osteoporosis.
