Manufacturer Narrative
|
The customer has not provided any additional information for investigation.Based on the available data, both a general instrument and reagent issue have been excluded since the sample was repeated several times and the qc results were always acceptable.Since the customer only noticed the difference in results between the roche instrument and the ortho method with this 1 patient, it is likely the issue is related to this specific patient sample (e.G.An interferent).The investigation did not identify a product problem.The cause of the event could not be determined.
