We have been having problems for the last month or so with D-dimer QC on our TOPS analyzers. We are using the regular HemosiL reagents and controls, and no matter what we do, the QC runs with a Mean close to the upper insert range limit on both controls. Does anyone else have this problem? We have been using these analyzers and IL products for over a year and now this happens. We are wondering if the formulation of the QC has changed. Once reconstituted, they are supposed to be good for a month in the fridge -- it appears to us that they may be only reliable for about a day. Thanks, Scott
