Evaluation of non-core laboratories
American Journal of Clinical Pathology
|September 1, 1978
Summary
Examining excluded laboratory data from the College of American Pathologists (CAP) Interlaboratory Survey reveals valuable insights. Analyzing these non-core labs improves understanding of analytical performance and data quality in clinical diagnostics.
Area of Science:
- Clinical Chemistry
- Laboratory Medicine
- Quality Assurance
Background:
- The College of American Pathologists (CAP) Interlaboratory Survey is crucial for assessing laboratory performance.
- Identifying and analyzing data from non-core laboratories provides unique insights into potential sources of error.
Purpose of the Study:
- To examine data from non-core laboratories identified in the CAP Interlaboratory Survey.
- To understand the reasons for laboratory exclusion and the effectiveness of exclusion criteria.
Main Methods:
- Analysis of data from laboratories designated as 'non-core' by Paule and Mandel.
- Categorization of non-core laboratories based on the nature of their discrepant results (e.g., unit errors, internal lab issues).
Main Results:
- Non-core laboratories were categorized into groups based on discrepant result causes: unit/specimen issues, internal lab problems, or acceptable results.
- The effectiveness of exclusion criteria varied across different analytes.
Conclusions:
- Data from excluded laboratories offer valuable supplementary information to central survey data.
- Understanding errors in non-core labs can enhance overall quality control and diagnostic accuracy in clinical settings.
