Age related changes to bone turnover markers. Blood samples from seventy healthy volunteers (33 males aged 19 to 62 years and 37 females aged 20 to 64 years), collected between 10–11 am, were analysed on the Elecsys 2010 (Roche, Lewes UK), for βCTX, P1NP and osteocalcin to verify the effect of age on bone turnover.
