Manufacturer Narrative

Customer reported that their acl top 500 cts reported erroneous aptt patient results using hemosil synthasil.Six patient samples generated erroneous results.All six samples were subsequently corrected.One patient received a bolus of heparin.The patient developed a superficial right groin hematoma.The customer was unable to determine if this was a result of the bolus of heparin.Service was dispatched to the site to inspect the instrument.No visual problems were observed, all performance checks passed, and quality control was acceptable indicating that the instrument was performing as expected.A review of the submitted instrument backup was performed and data for the patient receiving the bolus of heparin could be found, however, the other results could not be located based on the identifiers provided.It can be determined that the patient sample generated a result of 58.6 seconds without errors or warnings and then generated results of greater than 200 seconds approximately two hours later.While the root cause cannot be determined, there are many variables that have the potential to influence the result recoveries.These may include but are not limited to, the on-board stability of the reagent and cleaning materials, sample collection and processing, instrument maintenance, and service, etc.
