The VEDALAB EASY READER is an innovative meter for
reading immunochromatographic rapid test cards using a
high-resolution CCD-camera and integrated software
created for analysing pictures.
The EASY READER has a removable chip containing all
the necessary software for rendering quantitative or semiquantitative results from the test lines absorbance values.
Depending on the tested parameter, results can be obtained
from whole blood, plasma, serum or urine samples.
The meter also has an built-in printer for keeping archives of
all the information related to each patient (name, date of
birth and results) and to the user having performed the
analysis.

Principle of the reaction
Home
Start
If present in the sample, the analyte reacts with the colored conjugate
and flows to be caught by the reagents coated on the membrane. The
intensity of the colored band appearing in the test zone on the stick is
directly proportionnal to the concentration of the analyte.

The VEDALAB EASY READER is based on quantitative
immunochromatographic technology by measuring the intensity of the
reaction on a test cassette.
The CCD camera of Easy reader can measure the colour intensity and
determine the concentration of analytes in a sample.

Changing the E-prom
For the proper functioning of the EASY READER®, an E-prom (chip)
must be installed in the meter.
Each E-prom (chip) contains the calibration data specific to each
parameter or a range of several parameters.
The following instructions describe how to replace a chip.
Before changing the E-prom, switch the reader off

carefully the insert sheet for the calibration step,
to be properly informed. On the check-card
package are indicated the appropriate limits of
tolerance for meter results.
After selecting Check on the main menu, you will
be asked to insert the blank device to set the
baseline. Please follow the instructions.
It is recommended to check the meter before
starting the measurements. This process should
be performed once a week to verify that the
optical system of the reader is well calibrated.

Useful recommendations
Selecting Start means activating the real measuring menu.
By pressing the button below Start, a control is automatically
made in order to check whether there is a current zero line
setting or if such a setting should be done. In the case that a
new zero line setting is necessary, please follow the reader
instructions.
After successful zero line setting (or if such a process was
done on the last 24 hours and the meter was not switched off),
you will be asked to input the patient’s data needed to identify
the sample via the keyboard .

The reader does not require regular maintenance. With normal usage,
the device will not become dirty. The surface of the meter can be cleaned
with a slightly moistened, soft cloth. Please strictly avoid any liquid
penetrating into the meter. If needed, the black test card holder can be
completely pulled out of the meter and be cleaned with tap water.
Disinfection using isopropanol is possible. Please make sure that the test
card holder is completely dry before putting it back into the meter.
To obtain good and consistent results, you should note the
following:
a) Do not expose the instrument to direct sunlight or severe temperature
fluctuations.
b) Set up the instrument in humidity-free conditions.
c) Always keep the test card holder dust and dirt free.
