Inpeco Accelerator a3600 with Aliquoter Module: Clot Detection Error May Cause Erroneous
Inpeco recalls Accelerator a3600 Automation Systems with Aliquoter Module (FLX-212) that may dilute samples during error handling, leading to inaccurate lab test results. Affected units have specific firmware versions and serial numbers.
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.
