<scp>ASVCP</scp> guidelines: Allowable total error hematology

Abstract

Abstract The purpose of this document is to provide total allowable error ( TE a ) recommendations for commonly analyzed hematology measurands for veterinary personnel. These guidelines define relevant terminology and highlight considerations specific to hematology measurands. They also provide reasons and guidelines for using TE a in instrument performance evaluation, including recommendations for when the total observed error exceeds the recommended TE a . Biological variation‐based quality specifications are briefly discussed. The appendix describes the derivation of the hematology TE a recommendations and provides resources for external quality assurance/proficiency testing programs and a worksheet for implementation of the guidelines.
