Urine CrossLaps (CTX-I) is a biomarker test measuring degradation products of Type I collagen in the urine, indicating the rate of bone resorption. It is primarily used to manage postmenopausal osteoporosis, monitor the effectiveness of anti-resorptive therapies (like bisphosphonates), and assess metabolic bone diseases, often acting as a reference marker for bone turnover.
