GP44: Procedures for Handling, Transport, and Processing of Blood Specimens for Common Laboratory Tests, 5th Edition

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


CLSI document GP44 will provide information on handling, processing, stabilization, storage, transport, and receiving of blood specimens for common laboratory tests. This guideline describes the preexamination processes that link specimen collection to analytical testing. These processes are essential to maintaining specimen integrity and crucial to the quality of test results. GP44 can be used internationally to standardize preexamination processes and to satisfy regulatory and accreditation requirements. This guideline will allow laboratories to establish their acceptance criteria and their requirements for specimen integrity.

This group is looking for volunteers with:

  • Experience in the medical laboratory, particularly biochemistry and hematology
  • Experience in and knowledge of preexamination processes such as specimen handling (including centrifugation), stabilization, transport, receipt, and storage
  • Knowledge of time and temperature stability requirements for blood specimens
  • Knowledge of specimen integrity considerations and specimen acceptability criteria
  • Experience in manufacturing tube additives and centrifugation
  • Experience in regulatory or accreditation organizations

Additional information on essential job duties and skills and abilities for CLSI committee participants can be viewed here.
