i-STAT EG7 cartridge QC Issue

Tuesday, we discovered that our lot number of EG7 test cartridges were randomly failing Level 1 POC2 High. We had two lot numbers of QC available, and it was happening with both lot numbers. We are wondering if anyone else is experiencing this issue. The EG7 lot number is N25213, and the Level 1 QC lot numbers are 301190 and 301183.

We have the same lot numbers (Cartridges and QC) , and we haven't had any failures- neither when we validated the lot as new nor when we have validated new iSTAT analyzers.

We are also experiencing the occasional high PO2 but on EG7 lot 2515 with QC lot 301183. Very odd.

Thank you for letting us know. We have had other lots since then without any issues. I do not know what occurred everything was stored at the correct temperature. Who knows what happened between Abbott shipping the cartridges and our receiving them.

This thread is interesting, we recently had L3 QC out for TCO2 (reading < reportable range) on the Chem8 and all of the lactates (CG4)  also reading < reportable range.  The same QC lot, different shipment: recovered TCO2 accurately, but not lactate.  We are awaiting a new lot coming from Abbott technical service.  
All of our handling on our side seems consistent; the temperature cards never read greater than 1.  We have electronic monitoring of refrigerator temperatures, and there have been no alarms.
