Reason

Siemens Healthcare Diagnostics has identified an issue with Dimension Vista software v.3.7 and v.3.8.1 that may result in aliquot well contamination. If a test is cancelled by the operator while the instrument is aliquotting the sample, the Dimension Vista instrument may continue to deliver the cancelled sample or vial contents to the aliquot well(s). Future samples may be assigned to the same aliquot well(s) and become contaminated with the existing contents or overflow of the aliquot well may occur potentially contaminating a surrounding well(s). This issue only occurs when an operator manually cancels a test(s) for calibration, quality control (QC) or patient sample while the instrument is in the process of aliquotting the sample.
