Event or Problem Description
There was an allegation of a software issue for the cobas infinity core license.The reporter stated that they have a test rule called "hiv-flag-titermin" that, upon receiving the result from the "hiv-alar" test, it would enter a text result in the "hiv1" test.The reporter stated for a single sample from their run, the rule was not applied even though it met the rule's requirements.On troubleshooting, they copied the message sent by the equipment and simulated it, and the rule was applied.In the same run, there were other identical results where the rule was applied.
Additional Manufacturer Narrative
The investigation determined that the event was caused by a software issue in the cobas infinity.The simultaneous call of two methods in the source code has led to an error while trying to modify the test result.The rule that is responsible for the result modification is not executed properly as the rule execution process has stopped.This issue has been addressed.
