Why Quality Indicators Matter

Quality indicators are measurable values that help laboratories monitor performance and identify trends over time. CLIA and accrediting bodies expect labs to use data to evaluate their quality systems and drive improvement.

Core Laboratory Quality Indicators

1. Specimen Rejection Rates

Measures the percentage of specimens rejected due to labeling issues, insufficient volume, incorrect containers, or transport problems.

2. Turnaround Time (TAT)

Tracks the time from specimen receipt to result release, often segmented by test type or department.

3. Critical Value Reporting

Monitors how quickly critical results are communicated to clinicians and documented.

4. QC Failure Rates

Evaluates frequency and types of QC failures across instruments and test systems.

5. Proficiency Testing Performance

Reviews PT scores, unsatisfactory events, and corrective actions over time.

6. Incident and Complaint Rates

Counts and categorizes nonconformities, errors, and client complaints.

Using Indicators for Continuous Improvement

Quality indicators should not just be recorded; they should fuel decisions. Regular review allows labs to:

  • Identify processes that need redesign or training.
  • Prioritize improvement projects with the greatest impact.
  • Demonstrate performance to leadership and regulators.
