### Comments on Substantial Equivalence:

Models of the Dimension® clinical chemistry systems are designed similarly for the same purpose. They are floor model units that are microprocessor-controlled, integrated instrument systems that use prepackaged. Siemens Healthcare Diagnostics Flex® reagent cartridges and integrated ion selective multisensor technology to analyze a variety of analytes in human body fluids. The instruments spectrally analyze processed clinical samples using chemical and immunochemical methodologies. To ensure substantial equivalence with the Operating System change, representative methods were tested on instruments with ONX based software and compared to results of the same samples and methods on instruments updated with the Linux Operating System (revision 10.0 software). The representative methods, Na. K. Cl. GLUC, TSH and AST, were chosen to exercise different detection technologies on the instruments.

Comparative data for Method Comparison and Precision (with in run, within lab) demonstrate equivalent performance in evaluations of the representative methods.

### Conclusion:

The Dimension® clinical chemistry systems with the Linux Operating System (revision 10.0 software), are substantially equivalent in principle and performance to Dimension® clinical chemistry systems with QNX operating systems, based on the similarity of system design and comparative data from representative methods.
