  10. Joint Committee for Traceability in Laboratory Medicine ______________________________________________________ • Working Group II Procedure Manual • JCTLM WG2 P-02: • Process for Requesting and Processing Nominations for JCTLM Listing of Reference Measurement Services

  11. JCTLM WG2 – P-02 7. Procedure • 7.1 The process for nominating and reviewing RML services for recommendation by the JCTLM • for listing will occur annually (see flow chart in the Attachment). • 7.2 Solicitation of Nominations from RMLs wishing their services to be listed on the JCTLM List: • 7.3 Obtaining Nomination Forms: • 7.4 Submitting Nomination Forms for Consideration by WG2. • 7.5 Preliminary Review of submitted nominations for completeness by the JCTLM Secretariat. • 7.6 The JCTLM Secretariat and the WG2 Chair or the Chair’s designee review nominations • within six weeks of their receipt. • 7.7 Distributing Nominations from National Metrology Institutes to the JCTLM/CCQM Executive • Secretariat. • 7.8 Distributing Nominations from Accredited Laboratories (or Laboratories preparing for • Accreditation) to Review Teams. • 7.9 Any Review Team member affiliated to a nominating organization will not participate in the • evaluation of that reference measurement laboratory service if a potential conflict of interest • exists or is perceived to exist.

  12. JCTLM WG2 – P-02 7. Procedure (continued) • 7.10The distributed nominations from National Metrology Institutes are verified by the • JCTLM/CCQM Secretariat. • 7.11 The distributed nominations of Reference Measurement Service providers are • reviewed by the Review Teams. • 7.12 For laboratories where accreditation is pending(7.7.1.2) the status of • accreditation isre-examined in 2009 by the JCTLM Secretariat after consulting • WG2 chair. • 7.13 Reference measurement services listed on the JCTLM website will be re-reviewed • every three years. • 7.14 Any appeal against decisions of WG2 chair or review teams will be submitted to the • Secretariat and finally decided by the JCTLM Executive after consulting the WG2 chair.

  13. JCTLM WG2 – P-02 8. Requirements for acceptable proficiency testing scheme providers 8.1 The proficiency testing provider should organize intercomparisons dedicated to reference measurement laboratory services. 8.2 The proficiency testing provider should be accredited according to ISO Guide 43-1 (1997) and ILAC Guide G-13 (2000) by an ILAC member. 8.3 The proficiency testing provider should have an international scientific advisory board. 8.4 The proficiency testing provider should conduct intercomparisons regularly (at least annually). 8.5 The proficiency testing provider should ensure that communication is established and that scientific advice is available to resolve inter-laboratory discrepancies. 8.6 The proficiency testing provider should make publicly available the identity of the participating laboratories with their results and uncertainties.

  14. Joint Committee for Traceability in Laboratory Medicine ______________________________________________________ • Working Group II Procedure Manual • JCTLM WG2 P-03-A: • Process for Verification and Publication of Calibration and Measurement Capability (CMC) Claims in the JCTLM Database • (National Metrology Institutes)

  15. Joint Committee for Traceability in Laboratory Medicine ______________________________________________________ • Working Group II Procedure Manual • JCTLM WG2 P-03-B: • Process for Review of Reference Measurement Services from Laboratories that are Accredited as Calibration Laboratories • (ISO/IEC 17025 and ISO 15195)

  16. JCTLM WG2 – P-03-B 7. Procedure • 7.1 The process for reviewing RML services by the Review Teams will take place annually. WG2 chair • will send documentation from the candidate RMLs to the review teams. They will assess the • documentation and other publicly available information according to the following criteria: • 7.1.1 Review teams ascertain that the RML is accredited according to ISO/IEC 17025 and ISO 15195 as • calibration laboratory including on-site assessment by ILAC full memberson the basis of on-site • assessments by technical and management experts from accreditation bodies which are ILAC full • members. • 7.1.2 Review teams ascertain whether the Reference Method applied by the candidate laboratory is • listed by the JCTLM according to the WG1 procedure. If the applied method has not yet been • included in the WG1 reference method list the laboratory will be notified to nominate the procedure • for acceptance by JCTLM WG1. • 7.1.3 Review teams ascertain regular (at least annual) participation of the candidate laboratory in inter- • laboratory comparisons provided by an appropriate proficiency testing/external quality • assessment scheme for reference laboratories which fulfills the requirements of WG-2 P-02-8. • The results of the inter-comparisons as well as the result of the individual laboratory related to its • identity shall be publicly available. • It is also acceptable that a laboratory participates for another measurand of the same group of • quantities (e.g., metabolites & substrates, low-molecular hormones, therapeutic drugs, enzymes) • provided the same principle of measurement - e.g., IDMS, kinetic spectrophotometry for enzyme • activities - is applied.
