Event Description

The customer observed falsely decreased architect total bilirubin results for multiple samples when running on the architect c8000 processing module.The following sids were provided by the customer that generated initial results of < 0.1 mg/dl since (b)(6) 2023.The qc run right after and determined level 1 was out of range low and was not repeated.Level 1 qc once again was out of range low on (b)(6) 2023.All patient samples were re-tested on another architect c8000 and generated results within normal range.The customer immediately sent out corrected reports.The following repeat testing results were: patient repeat results (unit of measure: mg/dl) (b)(6) = 0.2, (b)(6) = 0.3, (b)(6) = 0.3, (b)(6) = 0.3, (b)(6) = 0.3, (b)(6) = 0.5, (b)(6) = 0.4, (b)(6)= 0.4, (b)(6) = 0.3, (b)(6) = 0.3.The customer¿s normal range for total bilirubin is 0.2-1.5 mg/dl.Through troubleshooting, the customer opened fresh calibrator, recalibrated the assay and ran qc.The qc is now on the mean for levels 1, 3, and the pediatric.No repeat testing on the analyzer after troubleshooting tasks were performed were provided by the customer.There was no impact to patient management reported.
