Aim

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

Objectives

  1. Identify a consensus reference standard marker for bone resorption (CTX) and for bone formation (P1NP) for fracture risk assessment and monitoring of osteoporosis treatment.
  2. Review the performance of the assays for the standard markers and recommend requirements for standardization of their measurements.
  3. Arrive at a consensus on the diagnostic cut-points and/or action limits for the bone turnover marker assays for intervention and alteration of therapy.
  4. Consult with key international organizations in order to gain international acceptance of the consensus of the WG and its implementation.
  5. Publish guidelines on the use of bone turnover marker assays for fracture risk assessment and monitoring of osteoporosis treatment.
  6. Define research questions that need answers in this area.
