Reason for Recall

As stated by FDA

The field action was initiated after an investigation for the Total Bilirubin reagents (List Number 8G62 and List Number 6L45) determined that the matrix of the secondary standard used in the value assignment of the calibrator is sensitive to the Diazo method. The matrix of this secondary standard caused a positive bias. Because of these findings, a new Total Bilirubin calibrator value assignm

On September 12, 2008, a Product Correction letter with an attached Customer reply form was mailed via US Postal Service to all affected customers that have received the affected lots. The letter instructed customers to take the following actions: 1. Identify the lot number(s) of Clinical Chemistry Bilirubin Calibrator currently used in your laboratory; 2. Replace the calibrator value sheet with the appropriate attachment provided with this letter. Discard the previous calibrator value sheet; 3. Configure the revised Total Bilirubin calibrator values provided in the Attachments, for the appropriate calibrator lot number and reagent list number. ARCHITECT cSystems: Refer to System Configuration in Section 2, Installation Procedures and Special Requirements in the Architect System Operations Manual. AEROSET: Refer to Calibrator/Control Configuration in Section 2, Installation Procedures and Special Requirements of the AEROSET System Operations Manual; 4. Calibrate the Total Bilirubin assay. Verify the calibration with at least two levels of controls according to the established quality control requirement for your laboratory; 5. Evaluate your quality control. Shifts in quality control and proficiency testing samples may vary among laboratories and should be evaluated according to your laboratory procedures. NOTE: Refer to the Attachments (E and F) for the representative shift with the revised calibrator values (Patient sample and Control/QC recovery); and 6. Evaluate your reference range and any shifts in patient results. It is recommended that each laboratory established its own expected ranges, which may be unique to the population it serves.
