The operator confirmed all reagents were handled in accordance with package insert directions, all quality controls (qc) are resulting in range, and there were no errors posted at the time of testing. Since the operator could not perform any additional troubleshooting, the operator called back and informed the ccc that repeat testing was performed to confirm the correct patient result.
