Course Overview
This 2-hour session covers identification and prevention of analytical errors/interferences in routine clinical chemistry and hematology testing via a combination of lecture and case-based discussion. Interferences are substances that can lead to erroneous test results either by incorrectly mimicking the desired analyte or by preventing measurement of the desired analyte resulting in pre-analytic or analytical error. Interferences are one type of analytical error while others may include but are not limited to equipment malfunction and reagent issues. Interferences are not uncommon and can occur in most assays in veterinary medicine resulting in both clinician and client frustration. Potential outcomes may include the need for repeat testing at the client or clinic expense or patient morbidity via incorrect treatment or unnecessary additional diagnostics. Prevention includes alterations in sample collection, sample type or alternate testing and confirmation. We will identify common artifacts and those that can influence care in an emergency setting and attempt to resolve these artifacts when possible.
Learning Objectives
Upon completion of this course, participants will be able to:
- 1Define and distinguish between pre-analytical, analytical, and post-analytical errors in veterinary laboratory testing.
- 2Identify common substances and conditions that cause laboratory interference, including EDTA contamination, lipemia, and hemolysis.
- 3Utilize blood film reviews and scatter plot analysis to verify automated CBC results and detect abnormalities such as nucleated red blood cells or pseudothrombocytosis.
- 4Apply age-appropriate and breed-specific reference intervals to avoid post-analytical interpretation errors.
- 5Implement standardized sample collection and handling protocols to minimize clinician frustration and unnecessary diagnostic costs.
