Quizplus · Accepted Answer

The QC results indicate a significant deviation from the expected values, as all six of the level I control values are +3s from the mean. This suggests a potential issue with the assay or instrument, and it is not appropriate to release patient results until the problem is resolved. Option A is the best choice as it involves holding all results, rejecting the run, and troubleshooting the issue to ensure accurate patient test results in the future.
