Area of Science:

  • Transfusion Medicine
  • Molecular Diagnostics
  • Quality Management Systems

Context:

  • The French Blood Establishment (EFS) conducted a national study on Nucleic Acid Testing (NAT) for HCV and HIV-1.
  • Transcription-Mediated Amplification (TMA) technology was evaluated at the EFS Pyrénées-Méditerranée Molecular Biology Laboratory.
  • Routine screening of blood and apheresis donations using TMA was implemented for two months.

Purpose:

  • To assess the efficacy of TMA technology in blood donation screening for viral infections.
  • To evaluate the application of Statistical Process Control (SPC) methods for monitoring NAT processes.
  • To identify challenges in post-investigation of process variations in an experimental setting.

Summary:

  • Daily operational data, including luminescence results (RLU) from calibrators and controls, were analyzed using SPC Control Charts.

Related Experiment Videos

  • SPC methods effectively monitored process drift and anticipated potential incidents during NAT screening.
  • The study highlighted the utility of industrial quality control methods for transfusion processes.

    • Impact:

    • Demonstrated the value of SPC for enhancing transfusion process quality and safety.
    • Identified difficulties in investigating uncontrolled process variations in experimental setups.
    • Showcased alignment with ISO 9000 standards for process control indicators and potential extension to other transfusion activities.
