Terms of Reference

  • To review current concepts of establishing reference intervals and decision limits and to prepare state-of-the-art position statements regarding new avenues
  • To make available reference intervals and decision limits that respect the requirements of international directives such as the European IVD Directive 98/79, and relevant ISO standards
  • To determine priority list of measurands (analytes) for which reference intervals and/or decision limits have to be developed, considering various factors, such as age, gender, ethnicity, and for which the greatest improvements in medical decision making are anticipated
  • To monitor and evaluate currently proposed reference intervals for selected measurands (analytes) in the light of the concept of traceability and of the identification of the uncertainty
  • To establish transferabilty protocols of reference intervals and decision limits, which take into consideration inter-routine laboratory method variations and achieve better applicability in clinical practice
  • To collaborate with other organizations and/or to undertake establishment of reference intervals or decision limits for measurands (analytes) identified as a priority
  • To work in close collaboration with other Cs and WGs of SD and other IFCC Divisions for the development and appropriate clinical utilization of reference intervals and decision limits


 

Current Projects

  • Conduction of a new study to compare alternative approaches (conventional and big data) for the determination of reference intervals
  • Creating a website to provide the reference intervals obtained from the global study for practice of Evidence Based Laboratory Medicine
  • Preparation of a publication on comparison direct and indirect approaches for the determination of reference intervals.
