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.\n\n## Affected lots\n1) Part Number C63519, UDI/DI 14987666545058 2) Part Number C63520, UDI/DI 14987666545065\n\n## Distribution\nWorldwide distribution - US Nationwide."}
