Clinical Chemistry ICT Calibrator, List Number: 1E46-02, Abbott Labs, Abbott Park, IL 60064

Quality Control (Out of Range)- ICT Calibrator lot number: 0505017, may contain an interferent. Not all vials within a kit are affected. The investigation determined that the interferent affects Potassium (K+) only. Use of the affected calibrator vials will generate an acceptable, but low calibration slope. When Quality Control (QC) is run to verify the calibration, K+ QC results may be bel

An Immediate Action Product Recall dated 9/26/07, was provided to all AEROSET and ARCHITECT cSYSTEM customers that have received Lot Number 0505017. The effectiveness check will be completed through a customer reply form for 100% of US customers. Outside of the U.S. each individual country will determine the methods of effectiveness check. Necessary Actions: If the ICT calibration generates an acceptable slope for (K+), and the calibration is verified by generating QC results within the acceptable range, then the customers may continue to use the lot until a new one is available. If the ICT calibration generates an acceptable slope for (K+) with results below QC range, and (Na+) and (Cl-) are not affected, then they should discontinue use of the Calibrator vials that generate the unacceptable calibration and destroy them following their laboratory procedures. If (Na+) and/or (Cl-) calibration slopes or QC results are not acceptable, additional troubleshooting is required. Questions may be addressed to Abbott Customer Support at 1-877-4ABBOTT.
