An August 10, 2007, Product Correction letter was provided to all ARCHITECT cSystem and AEROSET System customers. The letter advises that changes in a raw material used in the Bilirubin Calibrator value assignment process contributed to variability in the preparation of the NIST standard 916a. Revised Bilirubin values for the calibrator lot numbers in this recall are attached to the recall notice. Six necessary actions were listed in the recall notice as: 1) Identify the lot numbers of Clinical Chemistry Bilirubin Calibrator(s) currently in use. 2) Discard the value sheet and replace with the appropriate values provided with the recall letter. 3) Enter the revised Bilirubin values. 4) Calibrate the assays. 5) Evaluate your quality control. 6) Evaluate your reference range and any shifts in patient results.
