The Dimension EXL with LM system is a floor model, fully automated, microprocessorcontrolled, integrated instrument which uses prepackaged Siemens Dimension Flex® reagent cartridges to measure a variety of analytes in human body fluids. The system can process samples in random access, batch or STAT modes. The instrument has a heterogeneous module (HM) for processing chromium-based heterogeneous immunoassays and a LOCI® module for chemiluminescent immunoassays. The instrument can also perform photometric, turbidimetric and ACMIA tests. This 510(k) is being submitted because a new photomultiplier (from a different vendor) will be used to count the signal for the chemiluminescent methods (LOCI). The Dimension® FT4L Flex® regent cartridge consists of prepackaged liquid reagents containing two synthetic beads, and a biotinvlated anti-T4 mouse monoclonal antibody in a plastic eight-well cartridge. The FT4L method is a homogeneous, sequential, chemiluminescent immunoassay based on. LOCI® technology. The LOCI® reagents include two synthetic bead reagents and a biotinylated anti-T4 mouse monoclonal antibody. The first bead reagent (Chemibeads) is coated with trijodothyronine (T3), a naturally occurring, weaker binding analog of T4, and contains chemiluminescent dye. The second bead reagent (Sensibeads) is coated with streptavidin and contains a photosensitizer dye. In a first step, sample is incubated with biotinylated antibody which allows T4 from the sample to saturate a fraction of the biotinylated antibody that is directly related to the free thvroxine (FT4) concentration. In a second step, T3 Chemibeads are added and form bead/biotinylated antibody immunocomplexes with the nonsaturated fraction of the biotinylated antibody. Sensibeads are then added and bind to the biotin to form bead pair immunocomplexes. Illumination of the complex at 680 nm generates singlet . oxygen from Sensibeads which diffuses into the Chemibeads, triggering a chemiluminescent reaction. The resulting signal is measured at 612 nm and is an inverse function of the FT4 concentration in the sample.

In the ACE Glucose Reagent assay, glucose in serum reacts with adenosine triphosphate in the presence of hexokinase and magnesium with the formation of glucose-6-phosphate and adenosine diphosphate. Glucose-6-phosphate dehydrogenase catalyzes the oxidation of glucose-6-phosphate with NAD+ to form 6-phosphogluconate and NADH. NADH absorbs strongly at 340 nm, whereas NAD+ does not. The total amount of NADH formed is proportional to the concentration of glucose in the sample. The increase in absorbance is measured bichromatically at 340 nm/378 nm. The ACE Ion Selective Electrode (ISE) Module is used with ACE CAL A and CAL B Calibration Solutions in the performance of a two-point calibration in order to measure concentrations of sodium, potassium and chloride in undiluted serum. The ISE module uses a potentiometric method to simultaneously measure sodium, potassium and chloride in undiluted serum. Each electrode uses an ion-specific membrane to measure the difference in ionic concentration between an inner electrolyte solution and the sample. This difference causes an electro-chemical potential to form on the membrane of the active electrode. The connection of the amplifier and ground (reference electrode) to the ion selective electrode forms the measuring system. The two-point calibration with CAL A and CAL B with precisely known ion concentrations (two-point calibration) and the measured voltage difference of the sample and CAL A are used to determine the ion concentration in the sample.
