2 Safety information and warnings
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 sugar content in mg/dL. The measur-
ing unit mg/dL appears next to each blood sugar level reading. Be sure to contact
customer service if your measuring device does not display mg/dL. You risk damag-
ing your health if you perform a blood sugar measurement using an unfamiliar unit
of measure, since values may be interpreted incorrectly and cause the wrong correc-
tive measures to be taken.
•This measuring device must only be used by one person. There is a risk of infection if
the same unit is used by more than one person.
•The lancing device is suitable for household use. Never share the lancing device or needle
lancet with other people (risk of infection!).
•Use a new sterile needle lancet for each blood test (for one-time use only).
General notes
Warning
•Do not use the unit near strong electromagnetic fields, wireless systems or mobile
telephones.
Measuring blood sugar
Warning
•The measured values you determine are useful for information purposes only – they are not in-
tended 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 meas-
urement results.
•A very high or very low haematocrit value (proportion of red blood cells) can lead to incor-
rect measurements. With a very high haematocrit value (over 60%), the displayed blood
sugar value may be too low. If you have a very low haematocrit value (below 20%), the
blood sugar 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 sugar measurements of newborn infants.
•Metabolites such as ibuprofen, sodium salicylate, tetracycline, tolbutamide, unconjugated
bilirubin, cholesterol, creatinine, triglycerides, galactose, maltose, xylose, paracetamol, gen-
tisic acid, levodopa, dopamine, methyldopa, uric acid and ascorbic acid do not affect the re-
sult so long as they lie within the physiological value range.
•Do not use this unit to test any seriously ill patient.

Beurer GL40 mg/dL 9
Warning
•Lipemia effects: Increased blood triglycerides up to 3000 mg/dL hardly affect the results.
Above this level, however, the blood sugar test may be affected.
•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 swal-
lowed. 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 swallowed. Keep the container out of reach of young children.
The measuring device is made from precision and electronic components. The accuracy
of the measured values and service life of the unit depend on careful use:
•Protect the unit and accessories from impacts, moisture, dirt, large temperature fluc-
tuations and direct sunlight. Do not store the unit, the test strips and the control solu-
tion in a refrigerator, bathroom or car!
•Do not let the unit fall.
Batteries/Saving measured values
Warning
•Make sure batteries are not accessible to children. Children can put batteries in their
mouth and swallow them. This can cause severe harm to their health. In this case,
consult a physician immediately!
•Normal batteries must not be recharged, heated or thrown into an open flame (danger
of explosion!).

instructions.
Warning
•Each test strip is to be used only once and only for one patient!
Handling test strips
Note
•Once you have removed the test strip, tightly close the container again immediately.
•Do not use test strips if the expiry date has passed. The use of expired test strips can
lead to inaccurate measurements. The expiry date is located on the container next to
the hourglass symbol .
•The test strips can be kept for three months once the container is open. Make a note
of when this time will run out (date of opening + 3 months ) on the label. The shelf
life decreases if the expiry date is reached before the end of the 3 months (see the
date next to the hourglass symbol ).
•Do not use the test strips if either of these dates has expired ( / ).
•Any part of the test strip may be handled with dry, clean hands.
•Use the test strips immediately upon removal from the container.
•Do not bend, cut, or otherwise modify the test strip.
•Do not use test strips that have come into contact with liquids for the blood sugar mea-
surement.

5 Measuring your blood sugar
Warning
If you drop the lancing device with a needle lancet inserted, carefully pick it up and dis-
pose 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.
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 get blood samples from the fingertip or other parts of the
body, such as the palm, 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 sugar level can be measured quickly in blood
samples from the fingertip.
•Measuring from a fingertip and another part of the body (AST) can lead to significantly
different measured values. Always consult your doctor before starting to test at alterna-
tive sites.
2 Have the following components ready: Measuring device, container of test strips, lan-
cing device, 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 be-
fore beginning the measurement.

Beurer GL40 mg/dL 19
Taking the 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 intersti-
tial 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.
1 Twist to remove the cap from the lancing device.
2 Place 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 different cap depending on the site
from which you want to take the sample:
Fingertip: Cap (white)
Other parts of the body: AST cap (transparent)
Place the selected cap on the lancing device and twist it into
place.
5 Setting the puncture depth:
Five different puncture depths can be selected on the lancing
device:
•1 to 2: Delicate or thin skin
•3: Normal skin
•4 to 5: Thick or rough skin
Turn the cap in the corresponding direction until the arrow
points to the desired puncture depth.

20 Beurer GL40 mg/dL
6 Pull back the tensioning device until you hear it click into pla-
ce. If it does not engage, the lancing device may have unin-
tentionally already been tensioned when inserting the needle
lancet and could already be engaged.
7 The 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: z).
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 massag-
ing 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 apply-
ing pressure until the size of the blood drop is at least 0.6 mi-
crolitres (corresponds to approx. 1.4 mm, original size: z).
Lift the lancing device carefully away from the skin.
8 If insufficient blood was collected, increase the puncture
depth and repeat steps 5 to 7.
9 Untwist the cap and carefully remove it from the lancing de-
vice.
