Resolving QC Failures

Most medical technologists and technicians, responsible for outputting test results as quickly and reliably as possible, hate it when their smooth flow of work is abruptly interrupted by an out-of-control QC rule flag. Suddenly they are faced with delayed reports, the prospect of a complicated technical investigation, and a litany of questions they must ask themselves, such as:
  • “Is the out-of-control condition real?”
  • “Do I really have a problem with the analytical system?”
  • “If I do have a problem, when did it start and how many patient samples are affected?”
  • “What should I do first?”
  • “What should I do next?”
The laboratory would have much less of a conundrum if it were using a new QC rule proposed in a 2012 Clinical Chemistry article.1 This rule allows, as part of its process control, the possibility of a second set of QC measurements when the first results are inconclusive.
