Preanalytics in Blood Gas Testing - Importance of Sample Mixing

62% of all errors in relation to blood gas testing occur in the preanalytical phase.

A preanalytical error can jeopardize the final test result which ultimately could lead to incorrect patient treatment.

This webinar will review all steps in the preanalytical phase of blood gas testing focusing on all possible sources or errors and error prevention opportunities. A specific emphasis is centered around the area of “mixing a blood gas sample” in order to obtain a homogeneous blood sample.

This webinar will:

  • Describe the reasons why careful attention to the preanalytical phase helps to avoid risk to patients
  • Review the reasons why sufficient sample mixing is important to avoid bias on hemoglobin results
  • Identify the steps for healthcare providers to help avoid preanalytical errors
