The hazard
When racks are front-loaded onto the sample presentation unit while samples from the automation line are being processed, a scheduling error within the software can cause mishandling of samples during the creation of an aliquot and lead to incorrect results being generated. Affected samples typically yield non-reproducible falsely decreased results by up to 100%, however the potential for falsely elevated results cannot be ruled out.
