Reporting Name
Deoxypyridinoline Crosslinks, UrineThe Deoxypridinoline (DDP) Crosslinks test can be used as a tool to assess bone resorption rates in healthy individuals and in patients with enhanced risk of developing metabolic bone disease. Significantly high levels of Dpd are found in children, in postmenopausal women due to estrogen deficiency, and in patients with diseases that have high bone turnover rates. Dpd can be used to monitor antiresorptive therapies in postmenopausal women and in individuals diagnosed with osteoporosis.
