Risk of infection
All components of the measuring device and accessories may come into contact
with human blood, and are therefore a possible source of infection.
Warning
• This measuring device must display the blood glucose content in mg/dL. The unit of measure
mg/dL appears next to each blood glucose level reading. Be sure to contact customer service
if your measuring device does not display mg/dL. You risk damaging your health if you per-
form a blood glucose measurement using an unfamiliar unit of measure, since values may be
interpreted incorrectly and cause the wrong corrective measures to be taken.
• If the measuring device is used by more than one person, follow the generally applicable rules con-
cerning disinfection, safety and contamination.
• Medical professionals and others who use this system on more than one patient should be aware
that all products or items that come into contact with human blood should be handled as though
they could transfer pathogens, even after cleaning them.
• The lancing device is suitable for self-testing. Never share the lancing device or needle lancet with
others. Never use it on more than one patient (Risk of infection!).
• Use a new sterile needle lancet for each blood test (for one-time use only).

Measuring blood glucose
Warning
• The measured values you determine are useful for information purposes only – they are not intended
to replace consultation with your doctor. Discuss your measured values with your doctor regularly.
Do not change any aspects of your treatment unless instructed by your doctor.
• Water deficiency or a large loss of fluid, for example by sweating, can lead to false measurement
results.
• A very high or very low haematocrit value (proportion of red blood cells) can lead to incorrect meas-
urements. With a very high haematocrit value (over 60%), the displayed blood glucose value may be
too low. If you have a very low haematocrit value (below 20%), the blood glucose value may be too
high. If you do not know your haematocrit value, ask your doctor.
• Do not use the test strips to take blood glucose measurements of newborn infants.
• Metabolites such as ibuprofen, sodium salicylate, tetracycline, tolbutamide, unconjugated bilirubin,
cholesterol, creatinine, triglycerides, galactose, maltose, xylose, paracetamol, gentisic acid, levodopa,
dopamine, methyldopa, uric acid and ascorbic acid do not aect the result so long as they lie within
the physiological value range.
• Do not use this unit to test any seriously ill patient.
Warning
•Lipemia eects: Increased blood triglycerides up to 3000 mg/dL hardly aect the results. Above this
level, however, the blood glucose test may be aected.
•Only use fresh capillary whole blood. Do not use serum or plasma.
•Use capillary blood obtained without squeezing the puncture site. Squeezing causes interstitial fluid
to dilute the blood and leads to a false measurement result.
•Do not use the test strips at elevations over 3048 m.
Note
• The Beurer GL40 mg/dL measuring system is suitable for measuring capillary whole blood.
Storage and maintenance
Warning
• Store the measuring device and accessories out of the reach of young children. Small parts, such as
needle lancets, batteries or test strips, can be life-threatening if swallowed. If parts are swallowed,
seek medical advice immediately.
• The test strip container contains a desiccant that may cause skin or eye irritations if inhaled or swal-
lowed. Keep the container out of reach of young children.
The measuring device is made from precision and electronic components. The accuracy of the meas-
ured values and service life of the unit depend on careful use:

Warning
• If the protective disc on a lancet needle has already been removed, do not use the lancet needle.
• If you drop the lancing device while a needle lancet is inserted, pick it up carefully and dispose of
the lancet.
Important
• Use the lancing device only with needle lancets from the manufacturer. Use of other needle lancets
can impair the function of the lancing device.
• If the lancing device is manufactured by a third party, consult their instructions for use.

Beurer GL40 mg/dL 15
5.1 Acquiring blood samples
Preparing to take the blood sample
1
Choose a site on the body from where you wish to take the blood sample. You can use the
lancing device to take a blood sample from the fingertip or alternative sites such as the palm
of the hand, forearm or upper arm. We recommend that you take the blood sample from the
fingertip. To make the blood sample as pain-free as possible, do not take the blood directly
from the centre of the fingertip, but instead from slightly to the side of the centre.
Warning
• If you suspect hypoglycaemia: be sure to draw blood from the fingertip. This is because
changes in the blood glucose level can be measured quickly in blood samples from the fin-
gertip.
• Measuring from a fingertip and another part of the body (AST) can lead to significantly dier-
ent measured values. Always consult your doctor before starting to test at alternative sites.
2
Have the following components ready: Measuring device, container of test strips, lancing de-
vice, and a sterile needle lancet. If obtaining a blood sample from a site other than the fingertip,
you will also need the AST cap.
3
Before taking the sample, wash your hands using soap and warm water. In addition to optimal
hygienic conditions, this is also ensures good circulation of blood through the fingertips. Dry
your hands carefully. Also ensure that your lancing site is hygienically clean if taking a blood
sample from an alternative site (AST).
Warning
If you wipe the lancing site with alcohol, ensure that the site has dried completely before be-
ginning the measurement.
Taking a blood sample
Warning
• Change the prick point for each test, e.g. another finger or the other hand. Repeated pricks at the
same point can lead to inflammation, numbness or scars.
• Do not use the AST cap to take a blood sample from the finger.
• Never squeeze the finger to obtain a larger droplet of blood. Squeezing causes interstitial fluid to
dilute the blood; this can lead to a false measurement result.
• Note that inadequate circulation at the puncture site, for example caused by cold or illness, can lead
to inaccurate measurements.

16 Beurer GL40 mg/dL
1Twist to remove the cap from the lancing device.
2Place a sterile needle lancet in the lancing device and push
the lancet firmly into place.
3
Remove the protective disc from the lancet by twisting while
holding the shaft of the lancet firmly. Retain the protective
disc so that you can safely dispose of the used needle lancet
after taking the blood sample.
4
You will need to use a dierent cap depending on the site
from which you want to take the sample:
Fingertip: Cap
Other body parts: AST cap (transparent)
Place the selected cap on the lancing device and twist it
into place.
5Setting the puncture depth:
You can preset six dierent puncture depths on the lancing
device by turning the cap. A small bar means a shallow
puncture depth, and a large bar means a deep puncture
depth.
The dierence in puncture depth between the smallest and
largest click position is approx. 2 millimetres
•Smallbar(1to2): Delicateorthinskin
•Mediumbar(3to4):Normalskin
•Largebar(5to6): Thickorroughskin
Turn the cap to the required click position until the arrow in-
dicates the desired puncture depth.

Beurer GL40 mg/dL 17
6
Pull back the tensioning device until you hear it click into
place.
If it does not engage, the lancing device may have uninten-
tionally already been tensioned when inserting the needle
lancet and could already be engaged.
7The lancing device can now be used to take the blood sam-
ple.
Ensure that the blood remains in a droplet form and is not
smeared.
Blood sample from the fingertip
Place the lancing device firmly against the finger, slightly to
the side of the centre of the fingertip. Press the release but-
ton.
Lift the lancing device from the finger. You need a round
blood drop of at least 0.6 microlitres to form (corresponds to
approx. 1.4 mm, original size: ).
Blood sample from an alternative site (AST)
Choose a site that is soft, not next to a bone, with no visible
veins and without excessive body hair. Warm the puncture
site to ensure good circulation, for example by lightly mas-
saging
the area. Place and hold the lancing device against the
puncture site for a few seconds and press the release button.
Continue to hold the lancing device against your skin until a
round droplet of blood has formed under the cap. Keep ap-
plying pressure until the size of the blood drop is at least 0.6
microlitres (corresponds to approx. 1.4 mm, original size: ).
Lift the lancing device carefully away from the skin.
8If insucient blood was collected, increase the puncture
depth and repeat steps 5 to 7.
9Untwist the cap and carefully remove it from the lancing
device.

18 Beurer GL40 mg/dL
10 Place the protective disk you kept earlier flat on a hard
surface. Pierce the protective disk with the tip of the
needle so that the needle is covered.
11 Slide the lancet ejector towards the needle lancet until
the needle lancet is released from the lancing device.
Dispose of the lancet in a sharp-proof container.
Carefully dispose of all blood samples and materials
with which you have come into contact. This prevents
injury and prevents infection spreading to other people.
12
T wist the (white) cap back in place.
5.2 Measuring the blood glucose value
1Hold the measuring device so that the display is facing you.
2Insert a test strip, contacts first, into the unit. Ensure that the front side is facing you.
You can handle any part of the test strip with clean, dry hands.
3The unit switches on automatically and shows the start display. As soon as the hand
and symbols are flashing, the unit is ready to perform measurements.

Beurer GL40 mg/dL 19
4Hold the blood collection slit (at the point of the test strip)
against the blood droplet. Do not press the puncture site
(fingertip or other body part) against the test strip. The
blood must not be smeared. The blood is sucked into the
slit.
Warning:
Hold the blood collection slit of the test strip against the blood
droplet until the slit is completely filled and you hear a beep.
Withdrawing the test strip from the blood droplet before the
beep may lead to incorrect measurements.
5Once the slit is filled with blood, the unit performs the blood glucose measurement.
The measuring device counts down for approx. five seconds. Then the measurement
result is shown in the display.
Read the measured value.
For explanations and corrective measures concerning measured values, see the next
Chapter "Evaluating a blood glucose measured value", page 19.
If an error message is displayed, read the Chapter "Troubleshooting", page 26.
6Remove the test strip from the unit and dispose of it carefully in accordance with the
applicable guidelines in order to prevent infection of other people.
Note
• If the unit does not begin the measurement, do not subsequently apply more blood. Instead, remove
the test strip and end the test procedure. Start again using a new test strip.
• If the test strip is already in the unit and you do not put any blood on it within two minutes, the unit
switches o. Remove the test strip then and reinsert it into the slot, so that the unit switches on
again automatically.
• If you experience diculties applying blood to the test strip correctly, contact customer service.
• If you are measuring in a dimly lit room, press the ON/OFF button to switch on the unit.
The test strip area lighting turns on and makes it easier for you to insert the test strip.
In addition, the backlighting turns on for the results display.
5.3 Evaluating a blood glucose measured value
Your Blood Glucose Monitoring device can process measured values between 20 and 630 mg/dL.
The warning message " " is displayed for measured values below 20 mg/dL. The warning message
"" is displayed for a measured value above 630 mg/dL.
Warning
• If you suspect that the blood glucose values are incorrect, first repeat the test and, if necessary, per-
form a function test using the control solution. If you consistently have reason to doubt the results,
contact your doctor.
