Manufacturer Narrative
|
The assignable cause of the event is a known limitation of the vitros ckmb slide assay.
The results of the non-vitros fractionation indicate that 34% of the total ck enzyme in the sample consists of the macro type i isoenzyme.
Per the vitros ckmb slide assay instruction for use (ifu), macro ck type i and type ii can cause falsely elevated vitros ckmb results.
There was no indication the vitros ckmb microslide reagent or the vitros 5600 instrument malfunctioned.
