Event Description
|
One discordant falsely elevated and four discordant falsely low heparin results were obtained on a patient sample on a bcs xp system using a non-siemens assay.The sample was also repeated once more for heparin on the bcs xp system using innovance heparin reagent, resulting falsely low.The discordant results were not reported to the physician(s).The correct heparin result for this patient was reported to physician(s), but it is unknown which system and reagent were used to obtain the correct result.One discordant falsely elevated and two discordant falsely low heparin results were also obtained on a patient sample from a different patient on the same bcs xp system using a non-siemens assay.The sample was repeated a fourth time for heparin on the bcs xp system using a non-siemens assay, generating the correct result which was reported to the physician(s).The sample was also repeated once more for heparin on the bcs xp system using innovance heparin reagent, resulting falsely low.None of the discordant results were reported to the physician(s).There are no reports of patient intervention or adverse health consequences due to the discordant heparin results.

Siemens filed the initial mdr 9610806-2021-00001 on 05-jan-2021.Additional information (19-jan-2021): quality controls (qc) run using the innovance heparin reagent recovered in range at the time of the event.However, some of the qc run with the non-siemens assay did not recover in range at the time of the event.A siemens customer service engineer (cse) was dispatched to the customer site and ran a precision study using the non-siemens assay, which performed acceptably.Siemens cannot rule out pre-analytical factors such as sample integrity issues or interferences due to patient medication as potential causes of the event.The cause of the event is unknown.The system is performing according to specifications.No further evaluation of this device is required.
