Event Description

On (b)(6) 2017, a discordant, falsely elevated prothrombin time (pt) result, a discordant, falsely elevated pt international normalized ratio (inr) result, and a discordant, falsely low pt % result were obtained on a patient sample on the sysmex cs-2100i system.These discordant results were reported to the physician(s), who did not question the results.Due to the discordant results, the patient was administered an additional dosage of vitamin k.The patient's blood was redrawn and run on the same system, resulting in a lower pt result, a lower pt inr result and higher pt% result.On (b)(6) 2017, the initial sample was rerun on the same system, in duplicate, resulting in lower pt results, lower pt inr results and higher pt% results than the initial results.A corrected report was provided to the physician(s), but the results in the corrected report are unknown.There are no known reports of adverse health consequences due to the discordant, falsely elevated pt result, discordant, falsely elevated pt inr result, and discordant, falsely low pt % result.

Manufacturer Narrative

Siemens healthcare diagnostics (siemens) filed the initial mdr 9610806-2017-00153 on 28-dec-2017.Additional information (18-jan-2018): a siemens headquarters support center (hsc) specialist investigated the sysmex cs-2100i system's backup files and determined that the system was functioning according to specifications.The hsc specialist also determined that maintenance was regularly performed on the system, quality controls (qcs) were within expected ranges at the time of the event, and that the system correctly inspected the affected kinetics.A pre-analytical issue potentially contributed to the discordant results.Additional information (23-jan-2018): sysmex is the legal manufacturer of the sysmex cs-2100i system.Since the operator did not provide the malfunctioned lamp for further investigation and the age of the bulb is unknown, sysmex determined that the lifetime of the bulb was potentially exceeded.This potentially contributed to the discordant results.The cause of the event is unknown.The system and reagent are performing according to specifications.No further evaluation of this system or reagent is required.Mdr 9610806-2017-00154_s1 was filed for the same event.
