The most probable root causes associated with this failure mode are disconnected, faulty or damaged components, software/data corruption, or misuse.However, mitigations are in place to reduce and prevent such issues.All vital manufacturing steps are validated, monitored, and verified during manufacturing to ensure the system is in conformance with the verified design.All vital functions are monitored by the system and, when necessary, function is suspended to safeguard against inaccurate results.Labeling is provided to instruct the user on the intended use of all vital parts of the system to minimize misuse.All complaints and complaint trends are investigated to determine if there is a product defect/ deficiency.If a product defect/ deficiency is identified, a risk evaluation is completed and compared to the risk management report, to ensure the risk profile has not changed.Additionally, as a part of abbott¿s post-market surveillance process, all risk evaluations with associated complaint data are reviewed annually to determine if the risk profiles have changed as compared to the product risk management reports.These monitoring processes ensure that all product risk profiles remain acceptable and have a positive benefit/ risk ratio.The product has been requested back for an investigation.At this time product has not yet been returned.An extended investigation has been performed for the reported complaint and there was no indication that the product did not meet specification.The device history records (dhrs) for the freestyle libre sensor and freestyle libre sensor kit were reviewed and the dhrs showed the freestyle libre sensor and sensor kit passed all tests prior to release.If the product is returned, a physical investigation will be performed and a follow-up report submitted.All pertinent information available to abbott diabetes care has been submitted.

A high reading issue was reported with the use of the abbott diabetes care (adc) device.The customer received unspecified high sensor scan results compared to unspecified readings on the competitor brand device and experienced "black eyes," sweating, and shaking.The customer was unable to self-treat and required cola and sugar cubes from a non-healthcare provider for treatment.No further treatment was required.There was no report of death or permanent impairment associated with this event.

Sensor (b)(6) has been returned and investigated.Visual inspection performed on the returned sensor patch and no issue was observed.Data was extracted using approved software and extraction was successful.The watermark was not observed at the base of the tail.Sensor state 7 with event logs 11 and sensor state 8 with event log 9 are an indication that the sensor had terminated due to an error recognized by the sensor.This is a part of software design and is not an indication of product non-conformance.Smu (source measurement unit) test will be performed on the sensor to verify if sensor is functioning as intended.The returned sensor was further investigated and de-cased.Performed an internal visual inspection on the sensor¿s pcba (printed circuit board assembly); no issues were observed.Performed an smu (source measurement unit) test using connector key to ensure the sensor's electronics were functioning correctly and the returned unit did not have any glucose reading issues.Poise voltage and sensor thermistor testing were both within specification, indicating the sensor was providing accurate glucose readings.The passing of functionality (smu) testing is an indication that there were no issues with sensor functionality and electronics.Therefore, this issue is not confirmed.All pertinent information available to abbott diabetes care has been submitted.
