One member thinks that pre-analytic errors should not be considered lab errors, and should instead be designated as prelab errors. A couple respondents argued against this, however, because pre-analytic errors do include errors by lab staff, such as adding a test to the wrong patient sample. Another respondent also suggested that it would have a greater impact on quality to identify trends involving non-lab vs. lab errors in both the pre- and post-analytical phases, as this enables labs to better pinpoint both causes of error and solutions.
