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.
The provided text describes a 510(k) submission for several Dimension Vista™ Flex® reagent cartridges intended for diagnostic testing. The core of the submission is to demonstrate substantial equivalence to previously cleared predicate devices, primarily focusing on a packaging modification that allows these reagents to be used on the Dimension Vista™ integrated system. The reagents themselves and their fundamental scientific technology are stated to be the same as the predicate devices.
Here's an analysis of the acceptance criteria and study information based on the provided document:
1. Table of Acceptance Criteria and Reported Device Performance:
The document does not explicitly state numerical "acceptance criteria" or provide a table of "reported device performance" in the typical sense of a clinical study (e.g., sensitivity, specificity, accuracy against a gold standard). Instead, the demonstration of performance relies on comparative testing to show substantial equivalence to the predicate devices. The implicit acceptance criterion is that the performance of the new Dimension Vista™ Flex® reagent cartridges must be substantially equivalent to that of the predicate Dimension® Flex® reagent cartridges.
The text states: "Comparative testing described in the protocol included in this submission demonstrates substantially equivalent performance." and "Comparative testing also demonstrates substantially equivalent performance."
Since the document is a summary and not the full study protocol, specific performance metrics and their comparison values are not detailed. However, the nature of these in-vitro diagnostic tests typically involves:
- Precision/Reproducibility: Measuring the consistency of results when the same sample is tested multiple times.
- Accuracy/Method Comparison: Comparing the results obtained by the new device against a reference method (in this case, the predicate device results) using patient samples. This often involves statistical methods like regression analysis (e.g., Deming regression) to assess agreement.
- Linearity/Measuring Range: Confirming that the device accurately measures analytes across its claimed analytical range.
- Interference Studies: Assessing the impact of common interfering substances (e.g., hemoglobin, bilirubin, lipids) on the test results.
The key takeaway is that the "acceptance criteria" here are defined by the established performance characteristics of the predicate devices, and the new devices are deemed acceptable if their performance is statistially similar.
2. Sample Size Used for the Test Set and Data Provenance:
The document states: "Comparative testing described in the protocol included in this submission demonstrates substantially equivalent performance." However, it does not specify the sample size used for the comparative testing (test set) or the data provenance (e.g., country of origin, retrospective or prospective nature of the samples).
3. Number of Experts Used to Establish Ground Truth for the Test Set and Their Qualifications:
This information is not applicable in the context of this 510(k) submission. For in-vitro diagnostic (IVD) devices measuring specific analytes, the "ground truth" is typically the quantitative concentration of the analyte as determined by a reference method or the predicate device itself, not by expert consensus on qualitative interpretation. No human experts are described as establishing ground truth for the test set.
4. Adjudication Method for the Test Set:
This information is not applicable. Since the submission concerns quantitative measurements of chemical analytes, there is no need for an adjudication method as would be relevant for subjective medical image interpretation or clinical decision-making.
5. If a Multi-Reader Multi-Case (MRMC) Comparative Effectiveness Study Was Done, and Effect Size of Human Improvement with AI vs. Without AI Assistance:
This information is not applicable. The device is an in-vitro diagnostic reagent cartridge for laboratory analysis, not an AI-assisted diagnostic tool for human readers. Therefore, an MRMC study comparing human reader performance with and without AI assistance is not relevant.
6. If a Standalone (Algorithm Only Without Human-in-the-Loop Performance) Study Was Done:
The entire "device" described here (the reagent cartridges used on an automated analyzer) operates in a standalone (algorithm/system only) manner in terms of its measurement process. The Dimension Vista™ system is described as a "floor model, fully automated, microprocessor-controlled, integrated instrument system." The reagents enable this automated system to perform the quantitative measurements without direct human intervention in the measurement execution. Human involvement is in sample preparation, loading, and interpretation of the numerical results delivered by the automated system.
7. The Type of Ground Truth Used:
The ground truth for the performed comparative testing would have been the quantitative concentration of the specific analyte (Digitoxin, Digoxin, Gentamicin, N-acetylprocainamide, Phenytoin, Theophylline) as measured by the predicate device. Since the reagents themselves are stated to be the same as the predicate and only the packaging is modified for a new instrument system, the primary ground truth is established by the well-characterized performance of the predicate device on its intended system for each analyte.
8. The Sample Size for the Training Set:
This document does not mention a "training set" in the context of an algorithm or machine learning model. This is expected as the device is a reagent cartridge for a chemical assay, not a machine learning-based diagnostic. Therefore, information about the training set size is not applicable.
9. How the Ground Truth for the Training Set Was Established:
As there is no "training set" in the machine learning sense, this information is not applicable. The "training" of such a system involves the development and optimization of the chemical assay reagents and the instrument's detection capabilities during the initial development phases of the predicate devices and the Dimension Vista™ analyzer itself.

Comments on Substantial Equivalence:
The Dade Behring Dimension Vista™ Flex® reagent cartridges and the Dimension® Flex® reagent cartridges are designed similarly for the same purpose. Both contain prepackaged reagents for in-vitro diagnostic tests that are processed on microprocessorcontrolled, integrated instrument systems to analyze a variety of analytes in human specimens.
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 modifications do not affect the intended use of the devices, nor do they alter the fundamental scientific technology of the devices.
Comparative testing described in the protocol included in this submission demonstrates substantially equivalent performance.
Conclusion:
The Flex® reagent cartridges, containing reagents for testing DGTX, DIG, GENT, NAPA, PTN, and THEO on the Dimension® Vista™ Integrated system are substantially equivalent in design, principle, and performance to the Dimension® system Flex® reagent cartridges. They have the same intended use and indications for use. Comparative testing also demonstrates substantially equivalent performance.
