Sources and solutions for spurious test results in coagulation

Area of Science:

• Clinical Pathology
• Laboratory Medicine
• Hematology

Background:

• Rapid and accurate coagulation testing is vital in clinical laboratories.
• Inaccurate results can lead to misdiagnosis and inappropriate patient management.
• Errors can arise throughout the testing process, from specimen collection to result interpretation.

Purpose of the Study:

• To review common sources of spurious results in coagulation testing.
• To provide methods for identifying aberrant coagulation test results.
• To present strategies for minimizing errors in coagulation diagnostics.

Main Methods:

• Literature review of error sources in coagulation testing.
• Analysis of preanalytical, analytical, and postanalytical variables.
• Discussion of techniques for recognizing and mitigating inaccurate results.

Main Results:

• Identified patient variation, preanalytical issues, analytical testing, and postanalytical use as key error sources.
• Highlighted the potential for spurious results to impact clinical decisions.
• Outlined approaches for detecting and reducing coagulation testing inaccuracies.

Conclusions:

• Minimizing errors in coagulation testing is essential for patient safety.
• Implementing robust recognition and mitigation strategies can improve diagnostic accuracy.
• Addressing all phases of the testing process is key to reliable coagulation results.
