Both control values are above the acceptable range and outside of the established control limits. Before proceeding with patient testing, it is important to check the reagents' correct placement on the analyzer and correct handling. This is because incorrect placement or handling of reagents can affect the accuracy of the results. Rerunning controls may not be sufficient to correct the issue, and proceeding with patient testing without correcting the problem may result in inaccurate patient results.
