Demonstrating the Effects of Pre-Analytical Errors

Expires May 18, 2019

Presentation

 
Length: 52 minutes

Overview

One of the pre-analytic errors that can most profoundly influence chemical testing is specimen contamination. In this session, audience members will observe blood gas and electrolyte testing on native specimens. The audience will then be asked to predict the impact of deliberate contamination of blood gas specimens with air, or serum specimens with a solution used for total parenteral nutrition.

Objectives

Upon completion of this activity, participants should be able to:

  • Define major pre-analytical errors leading to specimen contamination for blood gas and chemical testing.
  • List chemical analytes most likely to be impacted by specimen contamination.
  • Predict the impact of air bubbles and total parental nutrition (TPN) contamination on blood gas and electrolyte testing.

Intended Audience

This program is appropriate for clinicians, pathologists, medical technologists, nurses, pharmacists, and other allied health staff.
