Working Groups

Standardisation of Bone Marker Assays as a part of the IFCC Committee Bone Metabolism (C-BM)

Members

Chair: E Cavalier

Members:
IOF: K Åkesson, O Bruyère, C Cooper, R Eastell, J Foldes, P Garnero, NR Jørgensen, JA Kanis, P Khashayar, N Lane, M McClung, S Silverman
IFCC: HP Bhattoa, V Delatour, A Griesmacher, A Heijboer, M Lorentzon, C Sempos, C Sturgeon, C Ulmer, S Vasikaran, H Vesper

Aim

This working group seeks to identify consensus reference standard bone resorption marker and bone formation marker for fracture risk assessment and monitoring of osteoporosis treatment.

Objectives

  • Harmonisation and standardisation of selected bone markers (CTX and P1NP)
  • Clinical usefulness of bone turnover marker levels
