Indications for Use

The AUTION MAX AX-4280 Urinalysis System (AUTION MAX) is an automated urine analyzer intended for the in vitro measurement of the following analytes: glucose (GLU), protein (PRO), bilirubin (BIL), urobilinogen (URO), pH, blood (BLD), ketones (KET), nitrite (NIT), leukocytes (LEU), specific gravity (SG), turbidity, and color. The AUTION MAX is intended for use only with the AUTION Sticks 9EB multi-parameter test strips.

Device Story

AUTION MAX AX-4280 is an automated urinalysis system for clinical laboratories. It processes urine samples using AUTION Sticks 9EB multiparameter test strips. The system includes an analyzer, sampler, and optional barcode reader. It uses reflectance spectroscopy to measure chemical analytes and color; refractive index for specific gravity; and light transmission/scattering for turbidity. The sampler automatically feeds racks of urine specimens into the analyzer. Software controls mechanical handling, processes user inputs, monitors system functions, and displays results. Results are exported via RS-232C interface. The system automates the analysis of urine physical and chemical properties, replacing manual or semi-automated methods to improve laboratory efficiency and provide standardized diagnostic data for healthcare providers to assess patient health.

Clinical Evidence

Bench testing only. Studies included correlation with a commercially available automated urine analyzer, demonstrating excellent agreement. Additional performance evaluations included precision, carryover, and linearity studies, all of which demonstrated acceptable performance for the intended use.

Technological Characteristics

Reflectance spectroscopy for chemical analytes and color; refractive index for specific gravity; light transmission/scattering for turbidity. Uses AUTION Sticks 9EB reagent strips. Mechanical rack-based sample handling. RS-232C connectivity. Software-controlled automation of analysis and data processing.

Indications for Use

Indicated for in vitro diagnostic measurement of urine analytes (glucose, protein, bilirubin, urobilinogen, pH, blood, ketones, nitrite, leukocytes, specific gravity, turbidity, and color) in clinical laboratory settings using AUTION Sticks 9EB test strips.

Regulatory Classification

Identification

An automated urinalysis system is a device intended to measure certain of the physical properties and chemical constituents of urine by procedures that duplicate manual urinalysis systems. This device is used in conjunction with certain materials to measure a variety of urinary analytes.

#### DEVICE DESCRIPTION 4.

The AUTION MAX Urinalysis System consists of an Analyzer, Sampler, and accessories. ARKRAY also offers an external printer and hand-held Bar Code Reader for use with the AUTION MAX. The sample-handling capacity of the AUTION MAX can be expanded through the use of the Extensional Sampler. The

#### INTENDED USE ર.

The AUTION MAX AX-4280 Urinalysis System (AUTION MAX) is an automated urine analyzer intended for the in vitro measurement of the following analytes: glucose (GLU), protein (PRO), bilirubin (BIL), urobilinogen (URO), pH, blood (BLD), ketones (KET), nitrite (NIT), leukocytes (LEU), specific gravity (SG), turbidity, and color. The AUTION MAX is intended for use only with the AUTION Sticks 9EB multi-parameter test strips.

### TECHNOLOGICAL CHARACTERISTICS AND SUBSTANTIAL EQUIVALENCE 6.

The AUTION MAX is substantially equivalent to the Clinitek Atlas Automated Urine Chemistry Analyzer with Rack Sample Handler (Clinitek Atlas), manufactured by Bayer Corporation (K946183). The Clinitek Atlas is intended for use with the Clinitek® Atlas® Reagent Pack reagent strips. Both the proposed AUTION MAX and the Clinitek Atlas measure urine GLU, PRO, BIL, URO, pH, BLD, KET, NIT, LEU, SG, color, and clarity.

The AUTION MAX is also substantially equivalent to the Chemstrip® Super UATM Automated Urine Analyzer (Chemstrip Super UA), manufactured by Boehringer Mannheim Corporation (K983510). The Chemstrip Super UA is intended for use with the Chemstrip® 10 S-UA urine test strips. The Chemstrip Super UA measures urine GLU, PRO, BIL, URO, pH, BLD, KET, NIT, LEU, and SG.

The proposed AUTION MAX Analyzer contains:

- Mechanical systems for handling the test strips, urine specimens, wash . solution, and system waste
- Measurement units for reading the test strips and analyzing the physical . properties of the urine
- Software control system for automation of Analyzer and Sampler operation, . processing commands and information input by the user, displaying system and specimen information, and monitoring system functions

{2}------------------------------------------------

- RS-232C interface for exporting measurement results and urine speciment . identification information
The AUTION MAX uses a rack system for urine specimen handling. The AUTION MAX Sampler automatically feeds sample racks to the Analyzer. The Sampler contains a Bar Code Reader for urine specimen identification.

The overall design of the predicate Clinitek Atlas and the Chemstrip Super UA is similar to that of the proposed AUTION MAX, with the exception that the urine specimens are transported to the Chemstrip Super UA analyzer using a turntable rather than a rack system.

The proposed AUTION MAX Analyzer uses reflectance spectroscopy for the measurement of the urine analytes GLU, PRO, BIL, URO, pH, BLD, KET, NIT, LEU, and urine color. Urine SG is determined using the refractive index method, and turbidity is evaluated by measuring the transmission and scattering of light passing through the urine specimen. These analytical methods are identical to the methods used by the predicate Clinitek Atlas. The predicate ChemStrip Super UA uses reflectance spectroscopy for the measurement of all urine analyte species, including SG.

The AUTION Sticks 9EB multi-parameter test strips contain reactive pads impregnated with reagents formulated to react with a specific urine analyte. Each strip also contains a correction pad with no reagents for urine color determination. Like the proposed AUTION Sticks, the Clinitek Atlas reagent strips and the Chemstrip 10 S-UA test strips consist of reagent pads on a non-reactive plastic backing.

The mechanisms of action for the chemical reactions used for the determination of urinary analytes, including glucose and occult blood, are similar for the proposed and The chemical constituents of the individual reagent predicate test strips. formulations are similar for the proposed and predicate reagent pads, with minor differences in the choice of enzyme substrate and chromogens used for production of the colored endproduct.

{3}------------------------------------------------

#### 7. PERFORMANCE TESTING

Several studies were conducted to evaluate the performance characteristics of the AUTION MAX Urinalysis System. A correlation study demonstrated excellent agreement when results from the AUTION MAX were compared to those from a commercially available automated urine analyzer. Additional studies for precision, carryover, and linearity demonstrated acceptable performance of the AUTION MAX System for its intended use.
