1 INTRODUCTION

1.1 Methodology of Urine Testing

Urinalysis is one of the medical diagnosis methods frequently used by medical

doctors in laboratories in order to reveal diseases.
This micro-chemistry system has been available for many years and allows
qualitative and semi-quantitative analysis within one minute by simple but careful
observation. The colour change occurring on each segment of the strip is
compared to a colour chart to obtain the result. However, misreading or
misinterpreting of results may happen, caused by individual handling habits of
different users or different light conditions.

1.2 Test Strips

The COMBILYZER Plus works with COMBINA 11S urine test strips:

Tested parameters are as follows:

Bilirubin
Urobilinogen
Ketones
Ascorbic Acid
Glucose
Protein
Blood
pH
Nitrite
Leucocytes
Specific Gravity

. Parts of COMBILYZER Plus

The COMBILYZER Plus is

designed for urine test strip reading.
The instrument includes two main
functional units:

- portable, battery-operated

Reader Unit for urine analysis

- bench-top, AC-powered Printer

Station, which docks with the
portable Reader Unit and
produces printed reports.

The Reader is menu-driven, so
the operator needs to set up the
Reader Unit first according to the
operational conditions with the
help of the function menus. After
placing the moistened urine strip
on the strip holder the instrument
reads and evaluates the strips
automatically.

Figure 2. The Reader Unit

The urine test strip containing chemical reagents is positioned under the reader's
sensor. After the pads' colours have been evaluated, the strip should be
discarded by the operator. The testing corresponds with the reaction time of the
chemical reagents - about 60 seconds.
The COMBILYZER Plus works using the reflectance photometry method: inside

the reader, the strip is illuminated by white light, and the light reflected from the
strip is detected by a colour CCD sensor. The RGB signals are digitised using
analogue-digital conversion. The digitised image is processed by a built-in
program: it locates the pads and, based on the reflected light, calculates the
results. The results, together with the current date, time and patient ID, are

stored and can be printed out by connecting the reader to the Printer Station.
The instrument is designed specifically for in vitro diagnostic professional use
and to meet the requirements of medical professionals. The measurement
capacity is up to 80 test strip evaluations per hour.
