Event or Problem Description
The initial reporter stated they received discrepant results for one patient sample tested with crej2 creatinine jaffé gen.2 (compensated) on a cobas c 111.No incorrect results were reported outside of the laboratory.The sample initially resulted in a creatinine value of 2.68 mg/dl and repeated as 0.44 mg/dl.The creatinine reagent lot number was 57929101, with an expiration date of 30-jun-2023.
Additional Manufacturer Narrative
A general reagent issue could be ruled out because calibration and quality controls were acceptable.The customer cleans the sample probe every 7 to 10 days.Per product labeling, the probe has to be cleaned manually on a weekly basis and deproteinized daily.The issue is consistent with a failed pipetting on the analyzer related to inadequate customer maintenance.
