Deoxypyridinoline, Urine, Ratio to CRT details
What Deoxypyridinoline, Urine, Ratio to CRT shows
Deoxypyridinoline is a cross-link molecule that holds collagen fibers together, and it is found mainly in bone. When bone is broken down, it is released and passed into the urine. This result is calculated by dividing the urine deoxypyridinoline concentration by urine creatinine, which corrects for how dilute the sample is. Higher values suggest faster bone breakdown, which can be seen after menopause, with some bone diseases and other conditions with high bone turnover, while values often fall with effective osteoporosis treatment. It varies through the day, so collection timing matters, and it does not diagnose osteoporosis on its own.
