External Quality Assessment of Bone Metabolism Marker Assays. Initial Experiences in a UK NEQAS Programme

  • Karen Marie Whitham and Anthony Milford-Ward

Abstract

This paper reports on a pilot external quality assessment scheme for bone markers including serum bone alkaline phosphatase and procollagen 1-carboxy terminal propeptide together with urine deoxypyridinoline, N- and C-telopeptides. The data shows poor numerical agreement between commercial assays, between-laboratory imprecision that could be improved, and the need for international standardisation of assays.
