Product Description
AggreGuide A-100 Instrument
Reason for Recall
The firm identified a software design issue where the improper shut down of the instrument resulted in speeds.csv file contents of the software version 5.1 being erased. Due to this issue, the target RPM for the assay is 0 and the motor output required to achieve this RPM is also 0. Therefore, when the assay is run, the software applies 0 Volts to the motor and performs a 0 RPM assay. Because of this, there is no mixing of the blood with agonist and no moving of aggregates happens in front of the optical detectors. The resulting PAI is 0 and the result is displayed as Low.
Distribution Pattern
International distribution to the country of South Korea.
Lot / Code Information

Frequently Asked Questions
A software recall means the device's embedded software or firmware has a defect that could affect its performance or safety. Many software recalls are corrected through firmware updates that can be applied without physically replacing the device. For implantable devices, the update may be delivered wirelessly during a routine clinic visit. For external devices, the manufacturer may provide updated software files or replacement units. Contact your healthcare provider to determine whether your specific device and software version are affected and what action is recommended.
Class I recalls indicate a reasonable probability of serious adverse health consequences or death from the defect. Class II recalls involve products that may cause temporary or medically reversible adverse health consequences, or where serious consequences are remote. Class III recalls cover products not likely to cause any adverse health consequences, typically involving technical regulatory violations. The classification guides urgency — Class I recalls require immediate action, while Class III may simply involve returning a product or acknowledging a labeling change. Always read the specific recall notice for recommended patient actions.
Report problems with medical devices to the FDA through MedWatch at 1-800-FDA-1088 or online at FDA.gov/safety/medwatch. Healthcare facilities are required by law to report device-related serious injuries and deaths. Patients and consumers can also report voluntarily. Include the device name, manufacturer, model number, and a description of the problem and any patient outcome. Reports from patients and clinicians help the FDA identify emerging safety signals and may trigger investigations that lead to recalls of dangerous devices.
