The FlexLab X System Sample Integrity Module (SIM) includes function that determines the hemolysis, icterus, and lipemia (HIL) in blood samples. This function has not been evaluated for safety and effectiveness by the FDA, so its use may cause an increase in erroneous results or a delay in patient results.

Firmware versions have the potential to mis-associate sample IDs leading to incorrect results or delayed sodium, potassium, and chloride patient results. Falsely increased or decreased electrolytes can lead to either inappropriate treatment of normal results, or failure to treat abnormal results resulting in abnormal levels. Abnormal potassium levels can result in weakness, polyuria, ileus, psychiatric disturbances, cardiac arrhythmias, respiratory depression, and death. Abnormal sodium levels can result in CNS disturbances and disturbances of water balance. Abnormal chloride levels can lead to acid base disturbances which can lead to respiratory and cardiac compromise. The event may occur only if all the following conditions occurs in few milliseconds timeframe: - The module is releasing a sample tube (Tube A) just placed into the carrier - Another sample tube (Tube B) is erroneously not diverted into the module buffer lane due to a malfunction of the divert gate Only in this specific scenario, the Tube A may be released by the module as Tube B due to a miscommunication between the module firmware and the Automation software without any error message. The Automation System loses the traceability of Tube A. It manages both Tube A (incorrectly identified as Tube B) and the real Tube B according to the test orders not performed yet on Tube B. Inpeco has released a Technical Service Bulletin with the procedure to correctly update the firmware. The firmware upgrade will be performed by Field Service Engineers. A CAPA (Corrective Action Preventive Action) has been opened to deeply investigate the root cause and identify possible process lack in order to avoid reoccurrences.

When a Clot Detection Error is generated during the sample aspiration from the Primary Sample Tube the aspirated volume is dispensed into the first empty Secondary Sample Tube. This Secondary Sample Tube is flagged with error 2132 or 1442 and sent to IOM Priority Output Racks to be manually managed. The current error message associated to error 2132 or 1442 recommends that the operator manages these Secondary Sample Tubes according to Laboratory Practice, but it does not clarify that these Secondary Sample Tubes may be diluted with water from the hydraulic circuit of the Aliquoter Module this may lead to reporting of erroneous results if the diluted sample is used for testing.
