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?
Adjust the acceptable range for quality control to encompass the deviated control results and maintain patient testing as per usual.
Continue to test patient specimens and note the deviation in the quality control log.
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.
