Dade Behring Dimension VistaTM Flex® reagent cartridges are prepackaged in-vitro diagnostic test methods (assays) that are specifically designed to be used on the Dade Behring Dimension Vista™ Integrated system, a floor model, fully automated, microprocessor-controlled, integrated instrument system. The Dimension VistaTM system was previously cleared with seven associated test methods (K 051087). This Special 510(k) is submitted for a packaging modification to in-vitro diagnostic devices that have been cleared under the 510(k) process for use on Dimension® clinical chemistry systems. The packaging change is to allow use on the Dimension Vista™ system. The reagents contained in the Dimension Vista™ Flex® reagent cartridges are the same as those contained in the Flex® reagent cartridges manufactured for the Dimension® clinical chemistry systems, another family of Dade Behring analyzers. The packaging modification, does not affect the intended use of the devices, nor does it alter the fundamental scientific technology of the devices.

Randox Laboratories Ltd. Digitoxin Test Kit is an in vitro diagnostic immunoassay for the quantitative determination of digitoxin in serum. Measurements obtained by this device are used in the diagnosis and treatment of digitoxin in the serum and in monitoring levels of digitoxin to ensure appropriate therapeutic levels.

The method includes a suspension of measuring particles coated with digitoxin conjugate. When a sample containing digitoxin is added, the digitoxin in the sample competes with the digitoxin conjugate on the particles for the limited amount of antibody in the reagent. The respective amounts of antibody bound to the digitoxin in the sample and to the digitoxin conjugate on the particles are inversely dependent on the concentration of digitoxin in the sample. The amount of antibody bound to the particles is measured by the agglutination process. When the antibody binds to the particles, agglutination occurs. When digitoxin is present in the sample, partial inhibition of the agglutination process occurs. The degree of agglutination is measured as a change in scattered light as a change in absorbance, proportional to the concentration of digitoxin in the sample.

The COBAS INTEGRA test applications contained in this submission are intended for use with the COBAS INTEGRA Analyzer. The COBAS INTEGRA Analyzer and COBAS INTEGRA Reagent cassettes together provide an integrated system for in vitro diagnostic testing. The COBAS INTEGRA Analyzer utilizes three measuring principles, i.e., absorbance, fluorescence polarization and ion-selective electrodes. The analyzer has a throughput of up to 600 tests per hour with STAT samples prioritized and tested immediately. Random sample access, robotics and a user interface optimize time management and streamline workflow. The COBAS INTEGRA can store up to 68 COBAS INTEGRA Reagent Cassettes on board, 24 hours a day at 2-8℃. The COBAS INTEGRA Reagent Cassettes are compact and preparation-free with the added convenience of long term on-board stability. Barcode readers are used to identify newly loaded reagent cassettes, samples for patient identification, and rack inserts and to read calibration and control data from the cassette label. COBAS INTEGRA tests include chemistry, drugs of abuse, immunology, ion selective electrodes, therapeutic drug monitoring, and hematology reagents. Through this submission, it is the intention of Roche Diagnostic Systems to gain clearance for an additional 4 COBAS INTEGRA Reagent Cassettes and 2 ancillary reagents as well as modifications to 7 previously cleared COBAS INTEGRA Reagent Cassettes. These reagents have been modified from granulate to liquid form.

The Chiron Diagnostics ACS:180 Digitoxin Assay is for the quantitative determination of digitoxin in serum or plasma using the Chiron ACS:180 Automated Chemiluminescence System. Monitoring of serum digitoxin concentrations is necessary to maintain therapeutic efficacy and avoid toxicity. Serum digitoxin levels combined with other therapeutic and clinical information provide the clinician with useful information to aid in adjusting patient dosage, achieving optimal therapeutic effect, and avoiding useless subtherapeutic or harmful toxic doses.

The Chiron Diagnostics ACS:180 Digitoxin assay is a competitive immunoassay using direct, chemilumenescent technology. Digitoxin in the patient sample competes with digitoxin, which is covalently coupled to the paramagnetic particles in the Solid Phase for binding to the acridinium ester-labeled monoclonal anti-digitoxin antibody in the Lite Reagent. An inverse relationship exists between the amount of digitoxin in the patient sample and the amount of relative light units (RLUs) detected by the ACS:180® system.
