The following steps show how to use the meter, test strips, code chip,
lancing device and sterile lancets together to measure your blood glucose
concentration. The main steps are as follows:
Step 1:
Step 2:
Step 3:
Step 4:
Blood Sampling
Before testing, first become familiar with how to collect blood and then
choose a clean and dry place to conduct the test.
IMPORTANT:
Prior to testing, use with either alcohol or soapy water to disinfect
the sampling site. Use warm water to increase blood flow if
necessary. Dry your hands and the sampling site, ensuring that
there is no soap residue remaining.
Insert the code chip into the glucose meter.
Insert the test strip (that corresponds with the code chip) face up
into the test strip port. The meter will automatically turn on and
display the code chip number and flashing “Apply Blood” icon.
You can choose the blood collection site. Usually a tiny amount
of blood is collected from the fingers, hands, or forearms. Touch
the blood drop lightly to the edge of the sample area. Complete
the test within two minutes, or the meter will automatically power
off.
After the meter detects that there is an adequate amount of
blood, the meter will count down 5 seconds and display the
glucose test results. The test result will be stored in the history
automatically. Slide the test strip ejector to eject the test strip,
and the meter shuts off automatically.

TTesting Your Blood


Pull back the cocking barrel until
you hear a click. Now the lancing
device is loaded and ready to
draw blood.
Before taking a blood sample,
wash your hands or use an
alcohol swab to clean the area.
Washing your hands in hot water
increases blood circulation. You
can also massage from wrist to
finger to promote better blood
circulation.
Holding the lancing device
against the side of the finger to
be lanced, press the release
button and then put down the
lancing device. Massage
forward slowly from the base
of your finger to the tip to
increase the sample size.
Wipe away the first drop of
blood and use the second drop
for the test strip.
Tip: To reduce pain, lance on
the sides of the fingertips,
where there are less nerve
endings. Rotate finger
locations as much as
possible to accelerate
wound healing and decrease
callouses.
Forearm or Palm Testing
Collecting blood samples from your palm or forearm may be less painful
than your fingertips because there are less nerve endings. The procedure
for collecting samples from your palm or forearm is slightly different. You
will need the clear cap for this type of sampling. You cannot adjust the
puncture depth with the clear cap.
IMPORTANT: There are important differences among forearm, palm
and fingertip samples that you should know. Important information
about forearm, palm glucose testing:
Please refer to "Fingertip Testing" sections 1-3 and 5 to learn how to install
lancets into lancets holder.
When blood levels are changing rapidly such as after a meal,
insulin dose or exercise, blood from the fingertips may show
these changes more rapidly than blood from other areas.
Fingertips should be used if testing is within 2 hours of a meal,
insulin dose or exercise and any time you feel glucose levels are
changing rapidly.
You should test with the fingertips anytime there is a concern for
hypoglycemia or you suffer from hypoglycemia unawareness.
Screw the clear cap onto the
lancing device.
Choose a sampling site on
your forearm or palm that is
dry and clean. Do not choose
an area near bone, visible
veins, or hair. To bring fresh
blood to the surface for
sampling, massage the site
vigorously until it feels warm.
Place the lancing device
against the puncture site. Press
and hold the clear cap against
the puncture site for a few
seconds. Press the release
button of the lancing device,
but do not immediately lift the
lancing device from the
puncture site. Continue to hold
the lancing device against the
puncture site until you can
confirm a sufficient blood
sample has formed.

Normal blood glucose target ranges (from ADA Clinical Practice
Recommendations, 2011).
Time Target Range (mg/dL) Target Range (mmol/L)
Empty stomach 70-100 3.9-5.6
2 hours after a meal <140 <7.8
(Note: 1 mmol/L = 18 mg/dL)
How many times per day should I test?
Diabetes Type Number of Tests With Empty Stomach
Type 1 At least 3 times per day
Type 2 Test frequently to achieve your target range
Prenatal Diabetes At least twice per day
“HI” and “LO” Messages
Your meter can accurately measure blood glucose concentrations
between 1.1-33.3 mmol/L (20-600 mg/dL). “HI” and “LO” messages
indicate that the test measurement was outside of this range.
If “HI” is displayed, it indicates the test result is above 33.3 mmol/L (600
mg/dL). You should test again to ensure that no mistake was made in the
procedure. If you are sure your glucose meter is functioning properly, no
mistakes were made, and the test results still show “HI”, then you may be
in a state of severe hyperglycemia, please contact your healthcare
professional immediately.
If “LO” is displayed, it indicates the test result is below 1.1 mmol/L (20
mg/dL). You should test again to ensure that no mistake was made in the
procedure. If you are sure your glucose meter is functioning properly, no
mistakes were made, and the test results still show “LO”, then you may be
in a state of severe hypoglycemia, please contact your healthcare
professional immediately.
“ “HYPO” and “HYPER” Messages
If “HYPO” is displayed, it indicates the test result is below the
hypoglycemia limit that you entered in the settings.
If “HYPER” is displayed, it indicates the test result is above the
hyperglycemia limit that you entered in the settings.
Research indicates that measuring your blood glucose at least three times
per day will help you control you glucose level. Please discuss the number
of tests and test times with your healthcare professional.
Record your blood sugar levels and other relevant information in your log
book. Bring your records when you visit your healthcare professional. It
will help him understand your condition, and help him modify your
treatment plan.


Blood Ketone Test Reminder: if “KETONE?” is
displayed, this indicates a blood ketone test is
necessary because your blood glucose test results
are higher than 16.7mmol/L (300 mg/dL).
Please contact your healthcare provider.
Notes:
This meter sytem is only for in vitro diagnostic use, and only can be
used with GoChek test strips. Use of other test strips can lead to
wrong test results.
This meter can only be used to determine blood glucose levels with
whole blood samples. Do not use serum or plasma samples.
This meter can be used within a hematocrit (HCT) range of 20% ~
70%. Please do not use this product for testing if your hematocrit
value is out of this range.
Abnormally high levels of Vitamin C (ascorbic acid) or other reducing
substances will produce falsely high blood glucose measurements.
Fatty substances, such as triglycerides less than 3,000 mg/dL or
cholesterol less than 500 mg/dL, have no major effect on blood
glucose test results.
Diabetic patients receiving dialysis treatment should do not use the
GoChek glucose meter and its test strips.
Patients who are severely ill, suffer from severe dehydration, or are in
a hyperosmolar state (with or without ketosis) should not use the
GoChek system.
This product is only suitable for clinical screening tests or family
self-monitoring. The test results can’t be referred to as confirmed
cases. In order to ensure the accuracy of the results, the test results
can be further confirmed by other methods, such as biochemical
methods.
As with all diagnostic reagents, test results must be linked with a
professional doctor’s diagnosis from the other clinical symptoms.
Carefully process waste caused by blood glucose tests according to
the relevant local laws and regulations, because blood samples are
considered a biohazard.
Press the “M” button to enter memory mode. The
“ ” icon and latest test result will be displayed.
If the blood glucose meter is used for the first
time, “---” and “ ” will be displayed.The date will
not be shown for the first test.
The stored test result along with the associated
time and date are displayed at the same time.
Test results marked with “#” icon will not be
included in the 7, 14, 30, 60 and 90 day
averages.
Press the “<” or “>” button to review all stored test
results.
Press button “M” again to enter the data average
screen. The number of days (“DAY AVG”) and
number of readings (“READINGS”) used in the
average calculation will be displayed. If no data
has been recorded, then the meter will turn off.
Meter Memory
Memory Mode
The glucose meter can store up to 500 test results with the
corresponding time and date. If 500 test results already exist, a new
result will overwrite the oldest one. The glucose meter also is capable of
calculating 7, 14, 30, 60 and 90 day averages from the stored results.


Memory Data Transfer
GoChek meters are capable of transferring memory data to a personal
computer. Please refer to the software instructions for correct usage and
the proper equipment to connect to your computer.
GoChek Connect and GoChek Connect+ meters can transmit data
wirelessly to other devices such as mobile phones. Please refer to the
additional user guide for more information.
Your blood glucose meter and laboratory equipment both report glucose
concentrations in the serum or plasma component of your blood.
However variations between the two are normal, and your meter results
and laboratory results may be slightly different. Glucose concentration
results can be affected by a number of factors and conditions, but these
factors and conditions will not affect the test results of biochemical
analyzers.
Under normal conditions, the difference between measurements with your
meter and laboratory results are within the range allowed by national
standards.
To ensure a reasonable comparison between your meter and laboratory
results, please follow these guidelines:
1.
2.
3.
4.
5.
6.
Test results may show small deviations, this may due to the following
reasons:
Blood oxygen and red blood cell count vary from person to person, and
even within the same person. GoChek glucose meters test blood glucose
concentrations for the widest range of people possible. If the user’s blood
indexes fall within the middle of the range, the result will be ideal.
Otherwise, there will be some small deviations. (The deviations should be
within the range allowed by local government.)
Comparing Meter and Laboratory
Results
Make sure your meter is working properly.
Comparisons will be more accurate if you do not eat for at least four
hours (preferably eight hours) before testing.
Bring your blood glucose meter, test strips, and control solution to the
lab.
Ensure that the time between tests with your meter and the laboratory
is within 15 minutes.
Wash and dry your hands before obtaining a blood sample.
Make sure you closely follow the instructions in this manual.
Press the “M” button again, and then use the
“<” or “>” buttons to scroll through the 7, 14, 30,
60, and 90 day averages. Press the “M” button
to see the before meal and after meal marker
averages. The meter will calculate the
historical averages according to the
parameters that you choose and the meter will
show how many records are used to calculate
the average.
If the meter has not been used for the amount
of time indicated as the “day average”, the
meter will not show an average.
Finally, press “M” one last time to turn off the
meter.
Note: Test results marked as quality control test
or with the “#” symbol will not be used in the
calculated average.
Clearing the Memory
Please be careful when using the clear memory function because the
action is irreversible. Once the memory is deleted, it cannot be restored.
The clear memory function will erase all test records.
While in the memory mode, press the “<” and “>”
buttons at the same time enter the clear memory
mode.
Press “M” to confirm that you would like all
records to be erased. The “ ” and "---" icons will
display at the same time, and the meter will turn
off automatically after a few seconds.
If you want to abort the memory delete function,
you can cancel by pressing the “<” and “>” button
instead of the “M” button. The memory will not be
erased.
