Risk of infection
All components of the blood glucose monitor and its accessories may come into contact
with human blood and are therefore a possible source of infections.
Warning
• This blood glucose monitor must display the blood glucose content in mg/dL. The unit of meas-
urement mg/dL accompanies each blood glucose value. Please contact our customer service
if the device does not display mg/dL. You risk damaging your health if you measure your blood
glucose value using a unit of measurement with which you are not familiar, misinterpret the
values and therefore take incorrect measures.
• When using the blood glucose monitor for various persons, please observe the generally applicable
regulations regarding disinfection, safety and contamination.
• Medical carers and others who use this system on several patients must be aware that all products
or objects that come into contact with human blood must be handled, even after cleaning, as though
they could transfer pathogens.
• The lancing device is suitable for self-testing. Do not share the lancing aid or the lancet needles with
others or amongst various patients (risk of infection!).
• Use a new, sterile lancet needle for each blood sample (for single use only).
General notes
Warning
Do not use the device in the vicinity of strong electromagnetic fields and keep it away from radio
systems or mobile telephones.
Measuring the blood glucose content
Warning
• The measurements taken by you are for your information only – they are no substitute for a medical
examination! Regularly consult your GP regarding your measured values. Do not alter the procedures
prescribed by your GP.
• Despite the simple usage of the Beurer GL44 monitor for self-monitoring of blood glucose levels, you
may possibly need to obtain instructions for using the system from your healthcare professional (for
example, your GP, chemist or diabetes consultant). Only proper use will guarantee exact measure-
ments.
• A lack of water, high fluid loss, for example perspiration, frequent passing of water, severe hypoten-
sion (low blood pressure), shock or hyperosmolar hyperglycaemic non-ketotic coma may lead to
incorrect measured results.
• A hematocrit value between 20% and 60% has no significant influence on the measurement results.
• An excessively high or low hematocrit value (proportion of red blood cells) may lead to incorrect
measurements. In the event of a very high hematocrit value (above 60%), the displayed blood glu-

Beurer GL44 mg/dL 9
cose value may be too low; in the event of a very low hematocrit value (below 20%), it may be too
high. Please consult your GP if you do not know your hematocrit value.
• Do not use the test strips to measure blood glucose values on newborns.
• Do not use NaF or potassium oxalate anticoagulants to prepare for venous blood samples.
• Do not test any severely ill patients using this device.
• Use fresh capillary whole blood only. Do not use serum or plasma.
• Use capillary blood without squeezing the penetration area. If the area is squeezed, the blood is di-
luted with tissue fluid and this may lead to an incorrect measuring result.
• Do not use the test strips above an altitude of 7010 m.
• Very high levels of humidity may influence the test results. Relative humidity of more than 90% may
lead to inexact results.
Note
• The Beurer GL44 mg/dL measuring system is intended to measure capillary whole blood.

Warning
• If the protective disc on a lancet needle has already been removed, do not use the lancet needle.
• If you have dropped the lancing aid with an inserted lancet needle, carefully pick it up and dispose
of the lancet.
Important
• Use the lancing aid only with lancet needles by the same manufacturer. The use of other lancet nee-
dles may impede the functionality of the lancing aid.
• If you are using a third-party lancing aid, please read the respective Instructions for Use.
5.1 Preparing to take a blood sample
1
Choose a part of the body from which to take a blood sample. The lancing aid is intended
for taking blood samples from the fingertip or other body parts such as the palm of the hand,
forearm or upper arm. We recommend taking blood samples from the fingertip. To make the
procedure as painless as possible, do not take samples directly from the centre of the finger-
tip, but slightly to either side.
Warning
• In the event of suspected hypoglycaemia: take blood from the fingertip only.
Reason: changes to the blood glucose level can be determined quickly in blood samples taken
from the fingertip.
• Blood samples from the fingertip and samples taken from another body part (AST) may lead
to completely dierent measured results. It is essential to seek medical advice before taking
measurements from other body parts.
2
Prepare the following items: blood glucose monitor, test strip box or test strips in film pack-
aging, lancing aid, sterile lancet needle. You will also need the AST cap for measurements at
other body parts.
3
Wash your hands with soap and warm water before taking a blood sample. This not only en-
sures optimal hygiene but also encourages good blood circulation at the puncture area on the
finger. Carefully dry your hands. Also ensure that the puncture area is hygienically clean when
taking blood samples from other body parts (AST).
Warning
If you have used alcohol for cleaning, ensure that the area has fully dried prior to measuring.

Beurer GL44 mg/dL 17
5.2 Taking a blood sample
Warning
• Change the puncture area for each measurement, e.g. a dierent finger or the other hand. Repeat-
edly using the same area may cause inflammation, numbness or scarring.
• Without the cap, there is a danger of injury from the exposed lancet.
• Do not use the AST cap to take blood samples from the finger.
• Do not squeeze your finger to obtain a larger drop of blood. If squeezed, the blood is diluted with
tissue fluid and this may lead to an incorrect measuring result.
• Please note that insucient blood circulation at the puncture area, e.g. caused by cold temperatures
or illness, may lead to incorrect results.
Important
Do not apply any blood samples or control solutions to the test strips before placing these in the
measuring device.
1Remove the cap from the lancing device.
2
Place a sterile lancet needle into the lancing aid and secure the lancet.
3
Rotate the lancet to remove the protective disc while holding the shaft
of the lancet. Keep the protective disc to safely dispose of the used
lancet needle after taking a blood sample.
4
Use various caps depending on the area from which you take the
sample:
Fingertip: Cap
Other body parts: AST cap (transparent)
Place the selected cap on the lancing device.

18 Beurer GL44 mg/dL
5Setting the penetration depth
You can set seven dierent penetration depths on the lancing de-
vice. The penetration depth is displayed by the markings in the cap.
• soft or thin skin
• normal skin
• thick or callous skin
Turn the moving upper part of the cap until the desired penetration
depth is displayed.
Note
When using the AST cap, penetration depth does not need to be set.
6Pull the tensioning device back until it audibly engages. Release the
tensioning device. This automatically snaps back into the default po-
sition. The lancing device is now ready for use.
7Put the already prepared lancing aid to one side and prepare the device for measurement.
8Take a test strip from the box/film packaging and immediately close it again.
9Hold the blood glucose monitor so that the display is facing you.
10
Firmly insert a test strip into the device with the contacts first. Please
make sure that the front is facing you. You can touch the test strip at
any point with clean, dry hands.
Use the test strip within three minutes of removal.
11
The device automatically switches on and shows the start display. The device is ready for
measurement as soon as the hand and the droplet symbol flash.

Beurer GL44 mg/dL 19
12 You may now use the lancing aid to take a blood sample. Please en-
sure that the blood remains a droplet and is not spread. Immediately
use the blood droplet to take a measurement.
Blood sample from the fingertip
The best penetration areas are the middle finger and
the ring finger. Firmly position the lancing aid slightly
to the side of the centre of the fingertip. Press the
trigger. Remove the lancing aid from the finger. A
round drop of blood of at least 0.6 microlitres (cor-
responds to approx. 1.4 mm, original size: ) must have formed.
Blood samples from other body parts (AST)
Find a soft area away from bones, without any visible blood vessels
and with as little hair as possible. Warm the penetration area to en-
hance circulation by gently massaging the area. Press and hold the
lancing aid against the penetration area for a few seconds and sub-
sequently press the trigger.
Continue to hold the lancing aid against the skin until a round drop
of blood has formed under the cap. Maintain the pressure until the
drop of blood reaches a size of at least 0.6 microlitres (corresponds
to approx. 1.4 mm, original size: )
Carefully lift the lancing aid o the skin.
Note
Only take blood from other areas at the following times:
• On an empty stomach (more than two hours after most recent meal).
• At least two hours after administration of insulin.
• At least two hours after physical activity.
Please also note the following:
• If the blood glucose test results do not match how you feel, carry out another test using blood
from the fingertips.
• DO NOT change your treatment purely on the basis of a measurement that was carried out
using blood taken from an alternative area. Carry out another test with blood from the finger-
tips in order to confirm the test result.
• If you often fail to notice that you have a low blood glucose level, carry out a test using blood
from the fingertips.
13
If there is an insucient amount of blood, repeat steps 1 to 12 with a greater penetration depth.
Note
When using the AST cap, repeat measurement at dierent parts of the body.

20 Beurer GL44 mg/dL
14 Hold the blood input gap (at the tip of the test strip) to the drops
of blood until the gap is completely filled and the measuring de-
vice in the display starts counting backwards. Do not press the
penetration area (fingertip or other body parts) to the test strip.
The blood must not be spread. The blood is sucked into the gap.
Note
Error message “002” appears on the display if the gap was not correctly and suciently filled
with blood. Repeat the measurement using a new test strip and a greater penetration depth.
Note
• Do not apply blood to the sides of the test strips
• Do not add blood later if the device does not start measurement. Remove the test strip and end this
test. Use a new test strip.
• The device switches itself o if the test strip has already been inserted into the device but no blood
is added to the test strip within two minutes. Briefly remove the test strip and reinsert it so that the
device automatically switches itself back on.
• Contact our customer service if you are unable to fully cover the test strip in blood.
• If you are measuring in a dark environment, press the On/O button to switch the device on. The test
strip light switches on and makes it easier to insert the test strip. The backlight is also switched on
in the results display.
5.3 Reading out result and highlighting measurements
Evaluating result
As soon as the gap is suciently filled with blood, the device performs the blood glucose measure-
ment. The blood glucose monitor counts down for approx. five seconds.
The measured result is subsequently shown on the display.
Read the measured values. For explanations and measures for the measured values, see chapter
“5.5 Evaluating measured blood glucose values”. If an error message is displayed, read chapter
“8. What if there are problems?”
Highlighting measured values
You have the following options to highlight measured values.
Before meals.
After meals.
General highlight (e.g. after exercising).
Highlighting measured values enables you, your GP or diabetes consultant to better check your
blood glucose values. For example, you can display the average values of all measurements taken
before meals.
