1. 3 2 QUALITY CONTROL RECOMMENDATION Following method verification and establishment of liquid quality control limits ITC recommends EQC as the primary method of assessing system accuracy and precision Since each test site may have unique require ments each site should select and verify a quality control system that meets their needs ITC recommends that QC be performed as follows RUN AN EQC TEST e Once per shift of patient testing on each analyzer e When the analyzer experiences a significant change in storage temperature e g movement from a cold to a hot environment e Whenever the performance of the analyzer requires verification according to facility or regulatory agency protocol RUN TWO LEVELS OF LIQUID CONTROL e Before a new cartridge lot or shipment is put into use following the required equilibration period to verify proper shipping and equilibration conditions Cartridge lot verification is not required for each analyzer in use ADDITIONAL LIQUID CONTROL TESTING e Is required only if cartridges are required to go through an additional equilibration period due to temperature fluctuations of greater than 8 C 14 4 F in the cartridge storage area Refer to Section 1 Cartridge Equilibration Procedure for additional equilibration information e If cartridges are required to go through an additional equilibration peri od run two levels of liquid control before putting the cartridge lot back into use
