Precision Data Series  

A Valuable Reference Tool for Maintaining Laboratory Integrity 

Laboratory Proficiency Program Precision Data Series is a valuable reference tool that can be used for determining the expected variability in the methods used in your lab.

Precision Data offers the results of the four rounds (8 samples) of the Laboratory Proficiency Program (LPP).

The results, compiled for each series and test method, are presented by number of analyses, number of outliers mean, standard deviation after outlier removal, relative standard deviation (RSD%), and reproduceability coefficient (R).

  • Compare your method performance data with an international peer group
  • Set product specifications
  • Compare the performance of your in-house method
