Introduction
1. Introduction 1.1. Methodology of the urine test The urinalysis is part of the medical diagnosis methods frequently used by medical doctors in laboratories in order to reveal diseases. The most cost-effective device used to screen urine is a reagent test strip. This microchemistry system has been available for many years and allows qualitative or semi-quantitative analysis within one minute by simple but careful observation. The colour change occurring on each test pad of the strip is compared to a colour chart to obtain the result. However, misreading or misinterpreting of results, caused by individual handling habits of the user or different light conditions, may happen. Urine analyzer (urine strip reader) equipment is designed specifically to improve the accuracy and security of urine strip evaluation by using light and photometric reader in order to detect the colour changes on the test strips. The CombiScan® 500 supports test data management and report generation by offering data storage and computerised data processing features. The CombiScan® 500 is a urine analyzer for professional use. The reader is a semi-automatic benchtop instrument designed to read the CombiScreen® 11SYS reagent strips. The operator needs only to feed the equipment by placing the moisturised strip on the conveyor – the rest, as forwarding, reading, evaluating and disposal of the strips is done automatically by the device. The timing (route-length and speed of the conveyor belt) is adequate to the incubation time of the test strip. The CombiScan® 500 analyses the colour and intensity of the light reflected from the reagent surface and reports the results in clinical meaningful units. No further calculation is needed by the user. When a strip is moved into the measuring position under the optical unit, the reflectance of each reagent pad is measured. The light reflected at specific wavelenghts from the test pad depends upon the degree of colour change of the pad, which is related to the concentration of the particular parameter in urine. The intelligent image analyzer software first detects, locates the strip and the pads, then, based on these colour light-wave information the CombiScan® 500 reads the reagent areas and the values are calculated automatically. Results are stored, then printed out by the built-in printer and can optionally be sent to host computer via serial connection.

Introduction
1.2. The test strips The base of the urine analysis is the good quality of the urine test strip. These strips have separated pads for each parameter. The test pads contain reagents, which cause colour changes according to the parameter concentration in the urine. The CombiScan® 500 is calibrated to CombiScreen® 11SYS urine test strips and guarantees accurate results all time. The CombiScreen® 11SYS urine test strip contains reagents for testing: Bilirubin Urobilinogen Ketones Ascorbic Acid Glucose Protein Blood pH Nitrite Leukocytes Specific Gravity Besides the CombiScreen® 11SYS, the CombiScreen® 11SYS PLUS can also be used with this instrument. To facilitate reading of the manual, the test strip is always named CombiScreen® 11SYS in this manual. IMPORTANT! Before using the test strip read carefully the CombiScreen® 11 SYS packing insert! The meter can only be used with the CombiScreen® 11 SYS urine test strip!
1.3. Intended use CombiScan® 500 is an instrument for measurement of urine test strips CombiScreen® 11SYS for in-vitro determination of Ascorbic acid, Bilirubin, Blood, Glucose, Ketones, Leukocytes, Nitrite, pH, Protein, Specific Gravity and Urobilinogen from urine. These measurements are used in the evaluation of diabetes, liver diseases, haemolytic diseases, urogenital and kidney disorders or metabolic abnormalities. For professional use, not for self testing.

The optical system is designed especially for evaluation of urine test strips. The test strip is illuminated by white light and the reflected light from the reagent strip is detected by a colour CCD sensor. The signals are digitalized and this digitalized image is evaluated by the built-in program.
Operation is very simple, and doesn’t require any special knowledge or difficult practice. When measurement starts, the front door opens and the conveyor assembled onto a carriage moves into the measuring position. The strip needs to be placed on the conveyor. Both the conveyor and the carriage are driven by a DC motor.
Description of the reader The carriage has three positions: Closed: The whole carriage is inside of the housing and the Frontdoor is closed. This is the stand-by or off position. Measurement: The front of the carriage is ejected of the reader housing in order to let the operator place the strip onto the three-belt conveyor. Maintenance: The carriage is fully ejected. In this position you can remove the belts and cylinders for cleaning. CAUTION! The carriage movement is controlled by the reader, never try to move it manually, not even when the reader is in stand-by or turned-off position! If the power shuts down when the carriage is ejected or an error occures, turn the reader off and on. The carriage will find its normal position automatically.

4.4. Start The reader can evaluate only the CombiScreen® 11SYS test strips. There is a calibration card enclosed to the strips. Each calibration card has an individual code. This code authorises the reader to read the strip. To read more about calibration see section 4.5.2.2. Users should always follow the appropriate federal, state, and local guidelines concerning the use of external quality control materials. There is no further special operation needed to calibrate the instrument before starting the daily routine urinalysis. It is recommended to use urine controls at least daily to check the system. It is possible to make measurements in sequence of samples or according to prepared worklist. If a worklist is stored in the reader „WORKLIST“ is indicated in the START menu on the left side of the first row of LCD (see below). Otherwise „MANUAL“ is displayed (see below). To learn more about the worklist refer to section 4.3. By selecting START the door will open and the conveyor will move out to be ready for measuring the samples. To stop operation press the STOP control key. The conveyor will stop running and slips back in “off” position and the door will close. The MAIN MENU will be displayed again. IMPORTANT! The reader will only stop operating if the conveyor is empty! The STOP command will only be accepted if the last strip detection and evaluation is over. If there is no strip detected for 5 minutes a STOP function will be executed automatically.

Operation 4.4.1. Measurement The day-to-day operation of the CombiScan® 500 is easy, and will be guided by the following lines. Have the urine test sample tubes prepared. Press the START control key. Insert an unused strip into the urine specimen, rinse it at the edge of the container, briefly dap the edge of the test strip on a tissue paper and place it on the conveyor with the test pads upside. Push the strip gently till it bumps against the strip-bumper. The strips must be positioned at right angles to the conveyor (see Fig. 7a, 7b). However, the system is able to compensate slight deviations. From this moment the testing process is controlled automatically by the CombiScan® 500.
Fig. 7a
Fig. 7b
Fig. 7: Positioning of the reagent strip. Fig. 7a shows the right positioning. Fig. 7b shows a wrong position. If you are in „MANUAL“ mode, you can enter a alphanumeric, max. 13 digit patient ID to be assigned to the next strip. You can enter the digits via the built-in numerical keypad or by using a barcode reader or external keyboard. Using the WORKLIST mode the next patient’s ID appears in the second row of the LCD. When a strip has been evaluated, the results are sent to the serial port. If a computer is connected to the reader, the data can be stored and displayed with the Analyticon CombiScanner Data Management software (see also section 4.6.). If the build-in printer is turned on, the results are printed out, too. After dipping the urine strips into the sample they can be placed on the conveyor. In a minimum distance of approximately 3cm to the prior strip. This allows a throughput of about 500 strips per hour. If you would like to skip a patient ID from the worklist, just select the “SKIP” option and the reader will delete the element and jump to the next item of the worklist or sequence number in manual mode. If during the work you reach the preprogrammed measurement counts (defined by the calibration card), a warning message will be printed. In this case you are still allowed to go on measuring an additional 1% of the named counts. Finish your work and perform a calibration process with a new calibration card (see section 4.5.2.2.). If you do not calibrate the instrument, it stops working until a new calibration is performed. After having finished your daily routine press the “STOP” key. The conveyor will stop running. Clean the instrument and emty the waste bin (see section 5.).
12
Operation Note: The following error messages may appear during the measurement process. „The waste bin is full!“ This message is accompanied by a short beep. It means that the waste bin has not been emptied for 150 measurements. Interrupt the measurement process and empty the waste bin, then continue working. “The waste bin is out!“ This message is accompanied by a short beep. It means that the waste bin is not in the right position. Maybe it wasn’t slipped back completely after emptying, or it has been opened accidently. Note: All instructions must be followed thoroughly to get accurate results!
4.4.2. Result printout The printed/sent results contain the following data: device type, date and time, sequence number of the test, patient identifier, result with analyte names, values, units, markings for pathological values and an end line.

Place the card behind the strip bumper close to the carriage. Before reaching the optical unit the conveyor will slow down and the sensor reads the code. The conveyor starts to move in reverse direction delivering back the calibration card. The stored calibration data will be printed out. CAUTION! Don‘t throw the calibration card away before the package of strips is completely consumed! If the calibration wasn‘t successful or you want to do the calibration manually, select MANUAL. The conveyor will move back into the housing. Now you can enter the 16 digit number which is printed below the first barcode. As soon as all numbers are entered, the code evaluation and calibration process takes place automatically. Details of stored calibration data will be printed out. To interrupt calibration select CANCEL or press the QUIT button.
