label_lc: decreased urinary lysyl-pyridinoline-hydroxylysyl-pyridinoline ratio
description: "A decreased amount of the urinary cross-links lysyl-pyridinoline (LP, or deoxypyridinoline DPD) as compared to hydroxylysyl-pyridinoline (HP, or pyridinoline PYD). Both are established biochemical markers of osteoclastic bone resorption and collagen degradation."
