Course includes study material and exam.

Description: Explore many of the ways spurious results may occur and the means to eliminate them. Most of these errors will be recognized and flagged by the instruments and their built in warning systems. There are, however, many potential pitfalls that can lead to reporting spurious laboratory results. Laboratory staff must be aware of these and know how to recognize and correct them. 

Start Date: Upon registration

Completion: Up to 52 weeks

Course/Activity Information

Learning Outcomes:

  • Identify and recognize spurious laboratory results promptly
  • Identify and classify the most likely encountered spurious Provide examples of both qualitative and quantitative errors
  • Tabulate the common errors that result from a pseudo increase or decrease in the value of common hematological measurements.
  • Identify the specific morphological features that indicate the cause of certain quantitative spurious results.
  • Outline the approach to minimize the errors caused by cold agglutinins.
  • Explain how calculated hematological indices are able to help identify errors in other test results.
  • Describe some of the more specific and common qualitative causes of spurious hematological test results.
  • List some of the common morphological abnormalities that are the cause of errors in instrument results.
  • Explain the limitations of the 100 cell differential count.
  • Describe the general approach to test results that do not agree with expected results in a given clinical condition.
  • Recognize the errors that result from delay in testing.
  • Understand the reasons that why differential counts should not be performed on buffy count films.
  • Describe the types of pre-analytical variable that might cause a spurious result
  • Describe the methods used by instrument manufacturers to detect spurious results
