a software defect in which the Parameter Package (PP) import logic overwrites all predefined calculated test rules, including those previously modified by the user, upon import of a new Parameter Package version. As a result, usercustomized calculated test rules revert silently to their default expressions, potentially generating erroneous patient test results without an explicit error notification. The issue affects instruments running software version 1.5 or lower and only occurs when a new Parameter Package is imported to a system that already has an existing Parameter Package onboard; new installations are not affected.

Beckman Coulter has identified that Access Total T4 Calibrator lots (PN 33805) exhibit a negative bias on DxI 600/800 instruments, with slopes outside product specifications. A false low patient result could cause a patient to undergo unnecessary additional diagnostic testing. A patient may be treated for a disorder not present or receive delayed treatment for hyperthyroidism. For a pregnant patient being monitored for thyroid hormone supplementation, incorrect treatment or dose may be used. A delayed patient results could cause repeat blood draw with associated complications.

Due to manufacturing issue (incorrectly processing) with in vitro multidrug resistant test.

Due to a manufacturing issue - missing a drug in well 4/4 but contain double the amount of antibiotics

Due to the likely presence of contamination in well(s).

Sample preparation system designed to automate staining, lysing, cell washing has a software error that causes samples to be dispensed close to or touching tube bottoms, which could dislodge fluid line, result in sample loss, spillage, make instrument inoperable and will lead to unintentional removal of 60-100 microliters from final sample, may lead to incorrect diagnosis or patient management.
