  • Validated materials for the different testing areas in a laboratory (such as chemistry, hematology, and microbiology) are provided several times a year.
  • Participating laboratories test the specimens and then return their results to the proficiency testing source.
  • The laboratory's performance is evaluated using the comparative method mean as the target value plus or minus a defined limit.
  • In general, the evaluation report will show:
    • number of laboratories comprising the peer group;
    • comparative mean of the group for that particular analyte;
    • the laboratory's performance compared to the peer group; and
    • whether the performance was satisfactory or unsatisfactory.
