Clinical Use:
Background: More than 90% of organic bone matrix consists of Type 1 Collagen. During normal bone metabolism, mature Type 1 Collagen is degraded. Small fragments pass into the blood stream and are excreted via the kidneys. During physiologically or pathologically elevated bone resorption (e.g. in old age or as a result of Osteoporosis) type 1 Collagen is degraded at an increased rate. This results in an increase of Collagen fragments in the blood.
