Introduction
1. Introduction
1.1. Methodology of the urine test
The urinalysis is part of the medical diagnosis methods frequently used by medical doc-
tors 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 sim-
ple 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-auto-
matic 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 rea-
gent 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 wave-
lenghts 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.

2. Description of the reader
The equipment is designed specifically for use in clinical laboratories. In its basic instal-
lation the housing is almost fully closed, its physical appearance including colour meets
the requirements raised by medical laboratories. Its throughput is about 500 test strip
evaluations/hour.
The optical system is designed espe-
cially 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.
Due to the CCD-technology, the instru-
ment is able to distinguish between
colour changes caused by reaction of
the test pad chemistry and non-spe-
cific colour development, caused by
the sample.
Operation is very simple, and doesn’t
require any special knowledge or dif-
ficult 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.
The used strips are collected in a waste bin located under the conveyor inside the Com-
biScan®500 (capacity: about 150 strips). If the automatic strip-counter reaches 150 you
will get a warning message which asks you to empty the waste-bin. To remove the waste-
bin just push and release its front panel. It will be automatically ejected. Pull it out totally,
empty it and insert it back. Slip it gently till it is bumping (see section 5.1.).
On the top side of the CombiScan®500 you can find the built in printer. If you open the
printer cover by lifting it’s front side you will get access to the paper roll cave to load
printer paper. For loading the printer paper refer to section 3 (Installation).
The interface connectors are located on the back panel. The external barcode reader and/
or keyboard can be connected to the keyboard interface connector. The host computer
can be connected to the RS232 serial port.

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 au-
thorises 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 ex-
ecuted automatically.
During operation the following informations are displayed on the LCD:

4.4.1. Measurement
The day-to-day operation of the CombiScan®500 is easy, and will be guided by the fol-
lowing 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.
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 Analyti-
con 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.).

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. Before each parameter name the pathological value is
marked with an asterisk (*). If one or more result classification limits (see section 4.5.1.2.2.
for changing sensitivity) have been changed, the bottom line of result starts and ends with
an asterisk (*----*). Each classification range has a name and a unit, corresponding to the
analyte.
Note: The printing on thermal paper may fade during storage, or if it is covered
with transparent tape.
4.5. Menu
The MENU offers the opportunity to adjust the instrument according to individual require-
ments, and to manage the data in memory. To carry out operations, select the MENU op-
tion in the main menu.

4.5.2.2. Calibration settings
The calibration card is delivered with the reagent strips. Each calibration card has an in-
dividual barcode printed on it. This code contains test strip related data and the number
of measurements that can be carried out after calibration. If the number of measurement
exceeds the predefined number, the reader will stop measuring, and a new calibration has
to be carried out.

If you select CALIBRATION, the conveyor will move to measurement position, but the con-
veyor will run faster than it does in the measuring modus. Place the calibration card with
the bar code upside on the conveyor. It must be placed at right angles to the conveyor in a
way, that the angle with the barcode is close to the meter. 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 cali-
bration data will be printed out.
To interrupt calibration select CANCEL or press the QUIT button.
4.5.3. Memory
The CombiScan®500 stores the last 999 results in memory. With the results, the se-
quence number, entered patient ID, time and date of measurement are stored as well. In
this MENU/MEMORY submenu you can clear results from memory or transfer stored data
to the built in printer or to a device connected to the serial port (i.e. host computer). To
achieve the functions mentioned above follow the flowchart below.
