1. Introduction

Accutrend®GC is a modern, reliable, and easy-to-use instru­ment for the determination of two important blood parameters:
glucose and cholesterol. Using the proven test-strip principle,
Accutrend

®

GC allows rapid monitoring of these blood values.

Accutrend

®

GC is also suitable for self-testing. With Accutrend

®

Glucose you can determine your blood sugar in only 12
seconds and with Accutrend

®

Cholesterol you can determine
your cholesterol level in 180 seconds.
The instructions below take you step by step through the
meter’s operation, cleaning and care. Please take time to read

 Before switching on the meter, open the flap

●

D by
gently pressing at the bottom edge. The respective
display elements will now remain displayed for a longer
time.

 Check whether the units displayed are the ones

required. Depending on the version of the instrument
the display will show either mg/dl (milligrams per
decilitre) or mmol/l (millimoles per litre) If you are not
sure whether you require mg/dl or mmol/l please ask
your doctor.
If the unit you are familiar with does not appear in the
display, please ask your dealer to exchange the instru­ment.

 Make sure that all three digits of the display appear as

888

. If any of the lines making up these digits are

missing, the values displayed later might be incorrect.

If at any time during the function test the display does
not correspond to either of the diagrams on the left,
please notify the Roche Diagnostics service (see pages
97 and 105).

2.3 Setting the time and date

The time and date of the Accutrend

®

GC can be set and
changed. The time must also be changed from summer to win­ter time and vice versa, and 29 February must be entered in a
leap year. The buttons are recessed to protect them from being
pressed inadvertently. To operate these two buttons you can
use – for example – a ballpoint pen.

For your data to be stored with the important information “date
and time”, these must first be set correctly.

The time can be displayed in either the 12-hour or 24-hour for­mat. If the 12-hour format is chosen, the time is displayed as
numbers from 1 to 12 with the addition of AM (before 12
noon) or PM (after 12 noon), e.g. PM 3:43.
If the 24-hour format is chosen, the time is displayed in num­bers from 1 to 24, e.g. 15:43.

The default setting for Accutrend

®

GC is the 24-hour format.
The following instructions describe how to change it to the
12-hour format.

2.4 Switching the beeper on and off

The beeper signals provide useful support.
For example, Accutrend

®

GC uses one beep to confirm
successful coding and a series of beeps to indicate the
approaching end of a measurement.
If the beeper is switched on, the bell symbol appears to the
right of the date. We recommend leaving the beeper switched
on. However, if you find the sound annoying you can switch off
the beeper as follows.

Accutrend

®

GC

3.1 Coding of the meter

The properties of the test strips can vary slightly from pack to
pack. Accutrend

®

GC must therefore be adjusted to accom­modate these differences. This adjustment is referred to as
coding.

It is performed with the help of code strips which enter the
specific characteristics of the respective Accutrend

®

Glucose

and Accutrend

®

Cholesterol strips used. Accutrend®GC must

be coded:

● After switching on for the first time, when no code number

is stored in the meter.

● Whenever a new pack of test strips is used. The instrument

is coded only for the pack from which you take the test
strips for the measurement of blood glucose or cholesterol.
Individually wrapped code strips are included in each pack
of strips.

During each measurement the coded meter performs the
essential checks automatically. Since each code strip and test
strip is characterized by a bar code on the back, the meter
recognizes whether a blood glucose (GLUC) or cholesterol
(CHOL) strip is being used. It then checks automatically
whether the code number on the inserted test strip is the same
as the code number it has stored. If the wrong test strip is
inadvertently used, the error message

e-1

appears.

GC

 Switch on the meter. When the function test is complete

the word CODE flashes. If the instrument has not been
coded before, the display shows

---

. If it has been

coded previously, the “old” three-digit code is displayed.

 Take the code strip out of the wrapping and hold it

between the thumb and forefinger with the arrows
pointing away from you. Be careful not to touch the
black horizontal line.

 With the flap

●

D closed, insert the code strip into the

slot

●

F in one smooth, brisk movement as far as it will
go, then withdraw the strip immediately. If the beeper is
switched on, successful coding is acknowledged by a
beep. The display shows a three-digit code number. The
code has been read in and stored.

If the error message

e-2

or

e-3

appears, coding was
unsuccessful (see Section 6.1). In this case, repeat the coding
as follows: open flap, close flap, insert code strip and then
withdraw again immediately.

After coding a measurement can be carried out with any test
strip whose code number is stored in the meter. When the test
strip is inserted the display automatically switches to the cor­rect symbol for the strip.

After coding do not throw away the test strip in case recoding
is necessary later on.

Store the code strip in its wrapping and not in the test
strip container because the print on the code strip may
impair test strip quality and lead to erroneous results.

3.2 Measuring glucose and cholesterol

3.2.1 Practising measurement

If you have little or no experience of self-monitoring and want
to get used to using the meter and the test strips you can prac­tise measuring without a blood sample. The procedure is iden­tical to that for checking the performance of the meter; go to
Chapter 5.1 “Checking the Measurement System” and follow
the instructions given there.

3.2.2 Performing a measurement

To perform a measurement you require:

● The Accutrend

®

GC meter which you have already coded;

you have also set the time, date and beeper.

● Accutrend

®

test strips (Accutrend®Glucose for blood glu-

cose measurement; Accutrend

®

Cholesterol for determina-

tion of cholesterol).

● A lancing device (e.g. Accu-Chek

®

Softclix®Pro with

Accu-Chek

®

Softclix®Pro Lancet).

● Possibly alcohol wipes and cellulose pads.

Procedure

Carefully read the pack inserts that come with the test
strips and the lancing device.

Warning! If measurements are performed on several
persons there is a potential risk of infection (e.g. hepati­tis, AIDS). Before using the meter for another person it

must be cleaned and disinfected each time (see Sec­tion 5). Please read the detailed description in Section

3.3 if you are performing measurements on several per­sons.
Users in the office and laboratory sector should note
that samples containing human material must be
handled as potentially infectious material. Please
observe the appropriate regulations and guidelines.

 Wash and dry your hands thoroughly.

 Prepare the lancing device.

 Switch on the Accutrend

®

GC.

When the function test is complete GLUC or CHOL
appears – or GLUC and CHOL alternately if the meter
has been coded for both.
The corresponding code number, the time and the date
appear below. The word CODE flashes and the
Accutrend

®

GC is now ready for the measurement of

the coded parameters.

 Take a test strip out of the test strip container. Close

the container immediately otherwise the desiccant in
the stopper will be exhausted and the test strips will
become unusable.

 With flap

●

D closed, insert the strip into the slot ●F in
the direction of the arrow with the square yellow test
area facing upwards until the strip locks into place and
the inscription GLU or CHOL on the test strip is no
longer visible.

Successful reading of the test strip code is indicated
by two beeps (one short, one long), if the beeper is
switched on, and by display of the test strip type: either
GLUC or CHOL. Then CODE stops flashing.

If the strip code has not been read in correctly, error
messages appear (e.g.

e-1, e-2

, or OFF). In this case,
consult Section 6.1 “Error messages” and follow the
instructions given there. If the inserted strip is not
shown correctly on the display (e.g. if GLUC is not dis­played although you have inserted an Accutrend

®

Glu-

cose test strip), switch off the meter and start again.

 Open the flap.

The measurement time in seconds flashes on the
display: 12 sec for GLUC, 180 sec for CHOL.

 Rub and knead the side of a fingertip to facilitate the

withdrawal and application of blood.

 Lance the massaged site with the lancing device.

 With the test strip still in the meter, allow a hanging

drop of blood to form without applying too much pres­sure. For determination of cholesterol wipe off the first
drop of blood with a cellulose pad and use the second
drop of blood for the test. Carefully apply the drop of
blood to the yellow test area (pad) on the strip without
touching the test pad directly with the finger.

The test pad must be completely covered with
blood, otherwise the results obtained may be
incorrect (i.e. too low). If too little blood is
applied, do not try to spread it or apply a second
drop as this may also produce incorrect results.
Repeat the measurement with a fresh test strip.

 Close the flap immediately after applying the drop of

blood. The display now counts down in seconds to

0

.
During the last four seconds a series of beeps is heard
(one beep per second), followed by a longer beep at the
end of the measurement. The measured value (in mg/dl
or mmol/l) appears on the display

●

A . The result is

stored.

Accutrend

®

GC measures values only within certain
ranges:
glucose 20–600 mg/dl (1.1–33.3 mmol/l)
cholesterol 150–300 mg/dl (3.88–7.76 mmol/l).
If the value obtained is above these ranges the meter
displays

hi

(= high), if the value obtained is below

these ranges the meter displays

lo

(= low).

The meter also displays

lo

when too little blood is
applied, i.e. if the yellow test pad is not completely
covered with blood. If this message appears, you should
therefore turn the test strip over and check whether the
round window on the back is uniformly coloured. If it is
only partly coloured, the measurement must be repeat­ed with a new test strip.

011553 AccuGC GB 19.02.2002 10:40 Uhr Seite 34

3.

36 37

The round test window must be completely covered
with blood, otherwise the results obtained may be
incorrect. This can lead to inappropriate treatment rec­ommendations and thus endanger your health.

If other messages appear on the display, consult Sec­tion 6.1 “Error messages” and follow the instructions
given there.

 Open the flap and take out the test strip.

Always open the flap before removing the test strip so
as to avoid soiling the instrument. The meter switches
off automatically after about 1 minute if no button has
been pressed or the flap has not been opened during
this time. If there is a test strip in the meter Accutrend

®

GC switches off after 2 minutes. The result is neverthe­less stored.

 For blood glucose measurements only: perform a

colour comparison to check plausibility.
a) Turn over the test strip
b) Compare the colour in the round window with the

colour scale on the label of the test strip container.
The colour in the round window must approximately
match the colour given for your result and the win­dow must be uniformly coloured.
If the colours do not match, please carry out a per­formance check (Section 5.1).

Too little blood applied – the
round window is not uni­formly coloured. Repeat
measurement with a new
test strip and application of
a larger drop of blood.

Sufficient blood applied –
the round window is
uniformly coloured

Back of test strip

011553 AccuGC GB 19.02.2002 10:40 Uhr Seite 36

3.

38 39

The colour comparison only serves as a plausibility check.
Treatment decisions should only be based on the result mea­sured by the meter.

The blood glucose determination is part of the treatment
plan agreed on together with your doctor. You should
therefore follow the doctor’s treatment recommenda­tions. If you receive unexpected or implausible results or
if the value shown does not reflect your subjective phys­ical condition you should check the performance of the
meter (see Section 5.1). If this shows that the meter is
functioning properly, please consult your doctor for
advice.

 Close the flap and switch off the meter.

The used test strips and other consumables (e.g. cleansing
pads, lancets) should be disposed of as household waste. In the
medical setting, e.g. laboratory or doctor’s surgery, the relevant
regulations or guidelines for the disposal of potentially infec­tious materials must be observed.

3.3 Measurements on several people

If the Accutrend

®

GC is to be used in the medical sector for
measuring blood glucose and cholesterol in several different
persons, special measures must be observed. The blood must
be applied to the test strips outside the meter. This is very
important as otherwise the flap and test-strip guide may
become contaminated with blood residues and there is a risk
of infection.

In order to prevent infection (e.g. hepatitis or AIDS) it is
essential to observe the following points:

 Only apply the blood outside the meter. Follow the

instructions in the section “Procedure for measurement
on several people” below.

 Use a separate lancet and lancing device for each

person. We recommend using the Accu-Chek

®

Softclix

®

Pro lancing device and Accu-Chek®Softclix®Pro

GC is used for performing measurements on sev­eral people and the blood is always applied to the strip using
an application device (e.g. capillary pipettes) the sample may
also be applied with the test strip in the instrument (see Section

3.2). In this case a new application device must be used for
each measurement.

4. Storing results in memory

4.1 Automatic storage of results

Accutrend

®

GC automatically stores the blood glucose and
cholesterol readings in separate directories. Safety warnings
such as

lo, hi

or

eee

are also stored. If the date and time
have been set (Section 2.3), these are displayed as additional
information with each individual value.

Accutrend

®

GC stores:
up to 50 blood glucose values in the GLUC directory,
up to 15 cholesterol values in the CHOL directory.
All values stored in the memory MEM can be retrieved or
deleted.

When you perform a measurement, the Accutrend

®

GC auto-

matically stores this latest result in the position

01

in the cor­responding directory. The previous value is moved automati­cally to position

02

. Thus, the higher the number of the
memory position, the older the value occupying this position.
When all available memory positions are occupied, the next
measurement automatically leads to deletion of the oldest
value from the directory and the latest value is stored in
memory position

01

.

Accutrend

®

GC

5.1 Checking the measurement system

In order to obtain reliable results you must check the perfor­mance of your meter at certain times. A performance check
should be carried out:

 once a week if you use the meter regularly and

frequently, e.g. for blood glucose self-monitoring,

 whenever you start a new pack of test trips and there-

fore recode the meter (which can lead to a change in
the code),

 whenever you have changed the batteries,

 after cleaning the meter,

 whenever you obtain a doubtful reading,

 in the medical setting, according to the guidelines or

regulations for quality control measurements applying
in your surgery or laboratory.

You will need the following:

 Accutrend

®

GC meter.

 Accutrend

®

Glucose and Cholesterol test strips.

 Control solution Accutrend

®

Control G and Accutrend

®

Control CH1.

Note:
The procedure for checking the measuring system is identical
to the procedure for practising how to perform a measure­ment. You can therefore practise performing a measurement
by following the steps described below for checking the
measuring system.

Procedure for the performance check

 Carefully read the pack inserts accompanying the test

strips and control solution.

 Switch on Accutrend

®

GC.
The meter first checks the electronics for about 2 sec­onds (as mentioned under 2.2) and then the word
GLUC or CHOL appears in the display. These different
blood components are also called “parameters”. The
corresponding code number, the time and the date
appear below the parameter name. The word CODE
flashes. Accutrend

®

GC is now ready to measure the

coded parameters.

 Take a glucose test strip, for example, out of the test

strip container. Close the container again immediately.

 Check whether the result displayed is within the speci-

fied range given on the label of the test strip container
or on a separate leaflet enclosed with the container.
If Accutrend

®

Control G 1 was used, for example, the
result must be within the range given in the first line
on the label (e.g. 50–90 mg/dl or 2.8–5.0 mmol/l). If
Accutrend

®

Control G 2 was used, the result must be
within the range given in the second line (e.g. 156–224
mg/dl or 8.7–12.4 mmol/l). Since the specified range
(confidence interval) may vary from pack to pack, it is
important to pay attention to any additional pack infor­mation.
Proceed in the same way for cholesterol.
If the measured value does not fall within the specified
range, repeat the performance check. If the result is
again outside the specified range, consult your nearest
Roche Diagnostics representative (for addresses see
page 105).
If the word OFF appears, please turn to Section 6.1
(“Error messages”) and proceed as instructed there.

5.2 Cleaning the meter

The essential prerequisite for accurate readings is cleanliness,
particularly in the area around the meter’s optics. The
Accutrend

®

GC should therefore be cleaned carefully and

regularly at least once a month. It should also be cleaned:

● as soon as the meter becomes dirty, paying particular
attention to the flap

●

D and to the test strip guide ●G ;

● if the control value is outside the specified range
(see Section 5.1);

● whenever you open a new pack of test strips;

● if someone else has used the meter.

Procedure for cleaning Accutrend

®

GC

 Check that the meter is switched off.

 Clean the outside with a damp lint-free cotton cloth.

 Remove the test strip guide

●

G . To do this, open the

flap

●

area around the measurement window

●

E , taking care
not to scratch the plastic. You should therefore use
only a soft, non-linting cotton cloth or cotton wool buds
for cleaning. These should only be damp so as to
ensure that no liquid can enter the meter.

If 70% ethyl alcohol is used for disinfection of meters
used in the medical sector, the alcohol should be
wiped off again immediately after application. Use only
70% ethyl alcohol for disinfection as other agents may
damage the plastic.

 Now insert the completely dry test strip guide

●

G into
the meter and press down gently until it clicks into
place.

 Make sure that the meter functions properly after

cleaning by performing a system check as described in
Section 5.1.

Make sure that the meter, particularly the measuring
window, is clean at all times as otherwise incorrect
results may be obtained.

5.3 Battery life and changing the batteries

Battery life

Normally at least 1000 measurements can be performed with a
fresh set of batteries. The system indicates that the batteries
are running low by continuing to display LOW BAT after the
function test. When this message appears it is still possible to
perform around 50 measurements before the meter can no
longer be switched on. If the power supply is interrupted for
too long, all data stored in the memory will be lost. You should
therefore change the batteries as soon as possible after LOW

BAT first appears.

Changing the batteries

Always change all three batteries at the same time. It is ad­visable to always have a complete set of three batteries in
reserve.
Use micro LR 03 type batteries (e.g. UCAR Micro 1.5 V AAA,
KODAK Micro or VARTA Micro AAA).

If the batteries are changed within 2 minutes no data will
be lost.

Hand in used batteries at collection points, or return them to
the shop for disposal.

Procedure for changing the batteries

Please proceed as described in Chapter 2.1
“Inserting/changing the batteries”.

5.4 Measurement and storage conditions

Please maintain the following conditions scrupulously every
time you perform a measurement. They are essential to ensure
precision and reliability of the measurements.

Temperature range for measurements

Accutrend

®

Glucose: +18°C to +32°C

Accutrend

®

Cholesterol: +18°C to +30°C

If a measurement is performed at a temperature outside the
ranges given above, the safety warning

TTT

flashes on the

display in alternation with the measured value.

The reading was obtained under temperature condi­tions outside the admissible range. It must therefore be
interpreted with particular caution and may only be
used for orientation.

Allow the meter and test strips to adjust slowly to room tem­perature. Never try to speed up the temperature adjustment by
placing on a radiator or in a refrigerator.

011553 AccuGC GB 19.02.2002 10:40 Uhr Seite 76

5.

78 79

Storage conditions

Do not store the Accutrend

®

GC at temperatures below –25°C

or above +65°C.

Humidity

In the presence of high humidity or large temperature changes
condensation may form on the meter, e.g. when it is taken
from a cold to a warm environment. In such cases Accutrend

®

GC either switches itself off or cannot be switched on (see
Section 6.1).
Allow the meter to warm up or cool down slowly at room tem­perature.

Possible sources of interference

Interference, e.g. frequent display of the safety warning

eee

,
cannot be ruled out in the presence of strong magnetic fields
such as those induced by transmitters (CB radio devices,
radios, televisions), household electrical appliances (micro­wave ovens, high frequency equipment), and particularly
mobile telephones. It is advisable to keep the meter at least
two meters away from such equipment. If the error warning
continues to display after moving the meter to a different
place, please contact your nearest service centre. See Section

8.4 for addresses.

6.2 Possible causes of errors

If the meter repeatedly displays error messages, or often gives
unexpected results, please check the following:

□

Have you checked the batteries?

□

Was the measurement performed according to the
instructions?

□

Have the test strips been stored and handled in
accordance with the package insert?

□

Has the shelf life of the test strips or the control solutions
expired?

□

Are the test strip guide and measurement window clean?

□

Were the test strips always from a pack whose code
number is displayed by the meter?

If you have checked these points and still obtain error
messages or doubtful values, please contact your dealer or
nearest service centre. See Section 8.4 for addresses.

7. Additional information for medical

personnel and laboratories

7.1 Measuring principle

An unused test strip is inserted into the meter. Light from an
LED (light emitting diode) is directed towards the test strip
from below and the blank value of the test strip determined by
measurement of the reflected light. Then a small drop of blood
is applied to the test area on the strip.

If the blood is to be applied outside the meter the procedure
described in Chapter 3.3 is used.

The constituent to be determined in the applied sample
undergoes an enzymatic reaction with formation of a dye, the
amount of dye formed increasing with the concentration of the
substance to be determined. After a certain period of time,
which is dependent on the test being performed, the meter
measures the colour intensity. This is done by directing light
from an LED towards the test area from below and measuring
the intensity of the reflected light with a detector.

For calculation of the result, the signal of the reflected light is
analyzed in relation to the initially measured blank value with
the help of the information programmed into the meter and the
information read into the meter from the code strip belonging
to the respective test strip pack.

The result is then displayed.
