Dimension Vista 500 Intelligent Lab System running on software versions V.3.6.1 SP1 or V.3.6.2, Device listing # D011374, All serial numbers and lots are affected. The Dimension Vista System is an in vitro diagnostic device intended to duplicate manual analytical procedures such as pipetting, mixing, heating, and measuring spectral intensities to determine a variety of analytes in human body fluids. Dimension Vista chemical and immunochemical applications use photometric, turbidimetric, chemiluminescence, nephelometric and integrated ion-selective multisensor technology for clinical use

Reason: Discrepant patient results on Dimension Vista Intelligent Lab Systems. Siemens Healthcare confirmed a software defect which, in a very specific set of circumstances, results in the Dimension Vista System omitting an aliquot probe rinse between sample aspirations when processing tubes in Sample Racks that are front loaded on the Dimension Vista System.
