The investigation found that only two tubes were placed in the rack at positions 3 and 4.There were several "warning order" warnings on the date of the event.The "warning order" error indicates errors occurred during processing of sample orders.Possible causes for the error are some sample orders could not be processed because there is not enough sample in the tube for the selected test profile, hardware errors occurred during processing of sample orders, or racks were transported to the output buffer before the sample processing was finished.There was also a "tube barcode cannot read" error, indicating the barcode label is missing, wrongly positioned, or damaged.The investigation reviewed data which showed that the analyzer handled the two samples and orders separately.It was also visible that the sample page was edited for the 4th tube.The investigation is ongoing.
