Formation markers: bone‑specific ALP, osteocalcin, P1NP. Resorption markers: CTX (C‑telopeptide), NTX, TRAP‑5b. Uses: monitoring therapy in osteoporosis and metabolic bone disease, not for diagnosis alone. Preanalytic variability: diurnal variation (fasting morning samples), renal/hepatic function influences.
