Study Notes

Importance of Laboratory Quality

  • Laboratory quality encompasses accuracy, reliability, and timeliness of test results, crucial for clinical and public health applications.
  • Even a 1% error rate in a laboratory can lead to significant negative consequences in health outcomes.
  • Inaccurate laboratory results can lead to:
    • Unnecessary treatments and complications.
    • Incorrect treatment provision.
    • Delayed diagnosis.
    • Unwarranted additional testing.
  • These issues contribute to increased costs and poor patient outcomes.

Key Factors in Minimizing Laboratory Errors

  • Achieving high accuracy requires meticulous attention to all laboratory processes and procedures.
  • Laboratories function as complex systems, demanding proper execution of numerous interlinked activities.
  • A quality management system (QMS) model is essential for enhancing laboratory performance by overseeing the entire operation.

  • ISO standards categorize laboratory processes into:
    • Pre-examination (pre-analytic).
    • Examination (analytic).
    • Post-examination (post-analytic).
  • The Path of Workflow describes the stages from patient sample collection to results reporting and interpretation.
  • Factors affecting laboratory quality include:
    • Laboratory environment.
    • Quality control protocols.
    • Effective communication.
    • Thorough record-keeping.
    • Skilled personnel.
    • High-quality reagents and equipment.

Components of Laboratory Quality

  • Core components of laboratory quality include:
    • Accuracy: Ensuring test results reflect true patient condition.
