The investigation determined that higher than expected vitros ckmb results were obtained from cliniqa quality control lot#: 2005075 processed on a vitros 5600 integrated system.The assignable cause of the event was not determined as inventory of ckmb lot 2821 was depleted.A review of historical cliniqa qc data with vitros ckmb lot 2821 indicated precision issues on all levels of control.A within run precision test was processed using cliniqa controls and acceptable precision and accuracy results were obtained indicating the vitros ckmb lot 2821 in combination with the vitros 5600 system was performing as expected at the time of precision testing.This would suggest a potential issue with day to day storage and handling of qc fluids but this was not confirmed.Therefore, pre-analytical qc fluid handling and storage could not be ruled out as a potential contributing factor to this event.A complaint review found no additional complaints for qc high or precision issues using this ckmb lot.In addition, continual tracking and trending of complaints has not identified any signals that would point to a potential systemic issue with this vitros ckmb lot#: 2821.Email address for contact office above is (b)(6).

The customer reported that higher than expected vitros ckmb results were obtained from cliniqa quality control lot #: 2005075 processed on a vitros 5600 integrated system.Cliniqa level 1 = 4.82, 4.85, 4.86, 4.81, 4.71 versus expected 3.03 ng/ml.Biased results of the magnitude and direction observed may lead to inappropriate physician action if they were to occur undetected on patient samples.The customer did not process ckmb testing on patient samples since qc was unacceptable.However, the investigation cannot conclude that patient sample test results would not be affected if the event were to recur undetected.There was no allegation of patient harm.This report corresponds to ortho clinical diagnostics inc.Complaint number: (b)(4).
