Device Description
The Hitachi Clinical Analyzer is an automatic, bench-top, wet chemistry system intended for use in clinical laboratories or physician office laboratories. The instrument consists of a desktop analyzer unit, an operations screen that prompts the user for operation input and displays data, a printer, and a unit cover. The analyzer unit includes a single probe, an incubation rotor, carousels for sample cups and reagent cartridges, and a multi-wavelength photometer. The single-use reagent cartridges may be placed in any configuration on the carousel, allowing the user to develop any test panel where the reagent cartridges are available. The S TEST reagent cartridges are made of plastic and include two small reservoirs capable of holding two separate reagents (R1 and R2), separated by a reaction cell/photometric cuvette. The cartridges also include a dot code label that contains all chemistry parameters, calibration factors, and other production-related information, c.g., expiration dating, dimensions of the reagent cartridges are: 13.5 mm (W) × 28 mm (D) × 20.2 mm (H). System operation: After the sample cup is placed into the carousel, the analyzer pipettes the sample, pipettes the reagent, and mixes (stirs) the sample and reagent together. After the sample and reagent react in the incubator bath, the analyzer measures the absorbance of the sample, and based on the absorbance of the reactions. it calculates the concentration of analyte in the sample. The test system can measure analytes in scrum or plasma and results are available in approximately 15 minutes per test. This submission is for reagent cartridge test systems for glucose.

calibration factors, and other production-related information, c.g., expiration dating, dimensions of the reagent cartridges are: 13.5 mm (W) × 28 mm (D) × 20.2 mm (H).

System operation: After the sample cup is placed into the carousel, the analyzer pipettes the sample, pipettes the reagent, and mixes (stirs) the sample and reagent together. After the sample and reagent react in the incubator bath, the analyzer measures the absorbance of the sample, and based on the absorbance of the reactions. it calculates the concentration of analyte in the sample. The test system can measure analytes in scrum or plasma and results are available in approximately 15 minutes per test. This submission is for reagent cartridge test systems for glucose.

Chemistry reactions (BUN):

Urea is degraded by urcase into ammonia. When glutamate dehydrogenase (GLD) reacts with ammonia and alfa-ketoglutaric acid to produce glutamic acid. NADPH is converted into NADP with a decrease of absorbance at 340 mm. The concentration of urea nitrogen can be determined by measuring the amount of change in absorbance.

Image /page/1/Figure/5 description: This image shows two chemical reactions. In the first reaction, Urea is converted to NH3 and CO2 by Urease. In the second reaction, NH3, Alfa-ketoglutaric acid, and NADPH are converted to Glutamic acid, H2O, and NADP by GLD.

Chemistry reactions (CRE):

As the first reaction, creatine in samples is decomposed into water and oxygen by the action of creatinase, sarcosine oxidase, and catalase. Subsequently, as the second reaction, creatinine in samples is converted into creatine by the action of creatininase, and then sarcosine is formed by creatinase. Then, the quinone pigment is formed by oxidation condensation between N.N-Bis (4-suffobuty)-3-methylaniline disodium salt (TODB) and 4aminoantipyrine in the presence of peroxidase (POD) and hydrogen peroxide is by sarcosine oxidase. The concentration of creatinine is determined by measuring the absorbance of the resulting quinone pigment (purple-red).

The first reaction:

Image /page/1/Figure/9 description: This image shows three chemical reactions. In the first reaction, Creatine and H2O react in the presence of Creatinase to produce Sarcosine and Urea. In the second reaction, Sarcosine, O2, and H2O react in the presence of Sarcosine oxidase to produce Glycine, HCHO, and H2O2. In the third reaction, 2H2O2 reacts in the presence of Catalase to produce O2 and 2H2O.

In the third reaction, Sarcosine, O2, and H2O react with Sarcosine oxidase to produce Glycine, HCHO, and H2O2. In the fourth reaction, H2O2, TODB, and 4-aminoantipyrine react with POD to produce Quinone pigment (purple-red).

807.92 (b)(2): Brief Description of Clinical Data

Studies for precision and method comparison (accuracy) were performed at three external POL-type sites to evaluate the Hitachi E40 Clinical Analyzer with S TEST Reagent Cartridges for BUN and CRE in one of its targeted intended use environments, the physician's office laboratory.

For the external site precision study. cach site received three blinded serum samples (the Precision Panel, labeled A. B. and C) that were chosen to represent low, middle, and high concentrations of BUN or CRE. Each sample was assayed six times per day for five days, reporting 30 results per level. Precision estimates for total precision were as follows:

For the BUN external method comparison studies, a series of approximately 75 serum specimens with BUN values ranging from 5.7 mg/dL to 73.6 mg/dL, were assayed on the Hitachi Clinical Analyzer E40 at three sites using S TEST Reagent Cartridge BUN (v) and a comparative method as the reference method (x). The same study design was used for the S TEST Reagent CRE, using approximately 45 serum specimens ranging from 0.6 mg/dL to 24.1 mg/dL CRE. Linear regression analyses (least squares) vielded the following results.
