Scope & Mandate

  • Develop an IFCC website highlighting all major national and international reference interval studies/programs in clinical chemistry and hematology.
  • Create a centralized global reference interval database hosted on the IFCC website by collating data from the completed templates. This database would enable users to search for major reference interval studies and view reference interval data. It would also have an interactive component in which the user could input a patient’s test result for comparison to available reference interval data within the database.
  • Create a harmonized tool for global users to upload data and calculate reference intervals using various statistical methods. Create an IFCC mobile app for easy access to the reference interval database.
  • Analyze global reference interval data to (1) create scatterplots of reference values in individuals from regions across the world, (2) assess potential similarities and differences in reference data between countries and/regions, and (3) assess opportunities for reference interval harmonization.
