Currently available serum markers of bone resorption include cross-linked C-telopeptide of type I collagen (ICTP) and tartrate-resistant acid phosphatase, as well as NTx and CTx. Of all the biochemical markers of bone turnover mentioned above, the ones most commonly used in clinical practice are BSAP, OC, urinary NTx, and serum CTx.
