Avoiding Errors in Veterinary Laboratory Diagnostics: Collection to Interpretation

Event Details

This comprehensive course addresses a critical challenge in veterinary medicine: the high frequency of diagnostic errors that occur before a sample even reaches the analyzer. Led by clinical pathologist Dr. Daniel Heinrich, the session utilizes real-world clinical cases to illustrate how common artifacts—such as EDTA contamination mimicking Addison’s disease or lipemia-induced pseudothrombocytosis—can lead to incorrect diagnoses and treatments. Participants will learn to navigate the complexities of laboratory data, from initial collection to final interpretation, ensuring higher diagnostic accuracy and improved patient outcomes.

The lecture emphasizes the importance of the 'gold standard' blood film and provides practical tips for troubleshooting 'not compatible with life' results. By understanding the limitations of automated analyzers and mastering the identification of common interferences, veterinary professionals can reduce the need for costly repeat testing and gain greater confidence in their diagnostic workups. This session is essential for any clinician or technician looking to sharpen their analytical skills and refine their laboratory workflow.

Learning Objectives

• Define and distinguish between pre-analytical, analytical, and post-analytical errors in veterinary laboratory testing.
• Identify common substances and conditions that cause laboratory interference, including EDTA contamination, lipemia, and hemolysis.
• Utilize blood film reviews and scatter plot analysis to verify automated CBC results and detect abnormalities such as nucleated red blood cells or pseudothrombocytosis.
• Apply age-appropriate and breed-specific reference intervals to avoid post-analytical interpretation errors.
• Implement standardized sample collection and handling protocols to minimize clinician frustration and unnecessary diagnostic costs.
