An ocd laboratory specialist observed a single non-reproducible, higher than expected vitros ckmb result from a non-vitros qc sample processed on a vitros 5600 integrated system.Non-vitros qc sample level 1: vitros ck-mb result of 4.508 ng/ml vs.Vitros assigned mean of 3.37 ng/ml.Biased result of the direction and magnitude observed may lead to inappropriate physician action if undetected.No patient samples were affected and there were no allegations of harm as a result of the events described.However, the investigation cannot conclude that patient samples would not be affected if the event were to recur undetected.This report corresponds to ortho clinical diagnostics inc.(b)(4).

The investigation confirmed that a non-reproducible, higher than expected vitros ckmb result was obtained from a non-vitros qc sample processed on a vitros 5600 system.Root cause of the higher than expected qc test result could not be determined, although the investigation could not exclude inappropriate pre-analytical sample handling / storage of the test materials as a possible root cause.The investigation also could not exclude unexpected vitros analyzer or ck-mb product performance as possible contributory factors.
