Osteocalcin, the most abundant non‑collagen protein in bone matrix, is a bone‑specific, calcium‑binding protein. Serum osteocalcin levels are related to the rate of bone turnover in various disorders of bone metabolism such as osteoporosis, primary and secondary hyperparathyroidism, and Paget's disease ([rupahealth.com](https://www.rupahealth.com/lab-tests/quest-diagnostics-osteocalcin-n-mid?utm_source=openai)).
