EP27: How to Construct and Interpret an Error Grid for Quantitative Diagnostic Assays, 2nd Edition

CLSI requests nominations for volunteers to serve as members and contributors on a document development committee for a document revision.


CLSI document EP27 will provide information on constructing and using error grids to evaluate the clinical acceptability of quantitative diagnostic measurement procedures based on the potential harm that may be caused by erroneous results. This guideline is applicable to many types of assays used in medical laboratories, including but not limited to laboratory-developed tests.

NOTE: This project will be developed through a pilot program for standards development. Click here to learn more.

This group is looking for volunteers with:

  • Expertise in statistical protocols
  • Experience in using error grids in medical laboratories, industry settings, or regulatory settings
