A medical assistant is performing quality control testing on a hematology analyzer used for complete blood counts (CBC). According to CLIA regulations, what is an appropriate action to take if the control results are outside the established acceptable range?
Troubleshoot the analyzer, repeat the quality control testing, and if still out of range, stop patient testing until the issue is resolved.
Use a previous lot of control materials to perform patient assays and verify if the current results are accurate.
Continue to test patient specimens and note the deviation in the quality control log.
Adjust the acceptable range for quality control to encompass the deviated control results and maintain patient testing as per usual.
When quality control results are outside of the established acceptable range, it indicates a possible issue with the analyzer's accuracy. The correct course of action is to troubleshoot the analyzer, repeat the quality control test, and if still out of range, hold patient testing until the issue is resolved and documented corrective actions are taken. Continuing to test patient specimens without addressing the issue can lead to inaccurate results and adverse clinical outcomes. Using the previous lot of control materials might still yield unreliable patient results, and reporting the results as usual would be incorrect and potentially harmful.
