RapidPoint 500 Quality Control

AQC is performed every 8 hours and is considered to be just like ampuled QC.  (which is why IQCP is not needed).
Does anyone not perform ampule QC (external) with every measurement cartridge change? 

Statement from Siemens
This cartridge-based system provides QC material in a standardized and unique manner that removes the need for operator intervention and ensures the running of specific levels of QC at specified time intervals, as regulatory requirements dictate or according to individual hospital protocol. 

It is important to note that cartridge-based AQC is just like ampuled QC, an external form of quality control. It is simply packaged differently and is more convenient. The AQC cartridge is entirely external to the measurement system, and the controls are value-assigned to a master lot by the manufacturer. The consistency of the manufacturing process allows the laboratory to consider their AQC as one long lot number with no expiration date. The elimination of room-air contamination allows the laboratory to consider using the data as one long shift on a day-to-day basis. This technology allows all laboratories to apply the same expected ranges over time for a given type of analyzer.
