Information
Intended use:
The KetoSens Blood β-Ketone Monitoring System is
intended for the quantitative measurement of β-Ketone
(beta-hydroxybutyrate) level in capillary whole blood
drawn from the fingertip. The KetoSens Blood β-Ketone
Monitoring System is intended for self-testing outside the
body (in vitro) by people with diabetes at home as an aid to
monitor the effectiveness of diabetes control. The system
is not intended for use in the diagnosis of or screening for
diabetes mellitus and is not intended for use on neonates.
This system is intended to be used by a single person and
should not be shared.
The KetoSens Blood β-Ketone Test Strips work with the
KetoSens Blood β-Ketone Meter to quantitatively measure
Blood β-Ketone in capillary whole blood samples drawn
from the finger.
The KetoSens Control Solutions are intended for use with
the KetoSens Blood β-Ketone meter and KetoSens Blood
β-Ketone test strip to check that the meter and the test
strip are working together properly and that the test is
performing correctly.
• Please use this device only for the intended use
described in this User's Manual.
• Please follow the suggested cleaning and disinfection
procedures described in this User's Manual.
To receive safe and optimum system benefits, please read
the entire manual contents before using the system.
Important Safety Information:
• The meter and lancing device are for single patient use.
Do not share them with anyone including other family
members. Do not use on multiple patients.
• All parts of the kit are considered biohazardous and can
potentially transmit infectious diseases, even after you
have performed pre-cleaning and disinfection.

Important Information
• The KetoSens Blood β-Ketone Monitoring System
is intended for self-testing outside the body (in vitro
diagnostic use).
• β-Ketone in blood samples reacts with the chemical in
the test strip to produce a small electrical current. The
KetoSens meter detects the electrical current which
reflects the amount of β-Ketone in the blood sample.
• The KetoSens Blood β-Ketone Meter is designed to
minimise code related errors in monitoring by using
the no-coding function.
• The KetoSens Blood β-Ketone Meter should be used
only with the KetoSens Test Strips.

Setting the Strip Expiration Date Indicator Checking the System
You may check your meter and test strips using the
KetoSens Control Solutions (level A and B).
The KetoSens Control Solution contains a known
amount of β-Ketone and is used to check that the
meter and the test strips are working properly.
KetoSens Control Solution ranges are printed on the
KetoSens test strip box. Compare the result displayed
on the meter to the KetoSens Control Solution range
printed on the test strip box.
Before using a new meter or a new box of test strips, you should
conduct a control solution test following the procedure on page
22–23 with two different levels of solutions (Control A and B).
Notes:
• Use only the KetoSens Control Solution (available for
purchase separately).
• Check the expiration date printed on the bottle. When you first
open a control solution bottle, record the discard date (date
opened plus three (3) months) in the space provided on the label.
• Make sure your meter, test strips, and control solution are
at room temperature before testing. Control solution tests
must be done at room temperature, 68–77 ˚F (20–25 ˚C).
• Before using the control solution, shake the bottle, discard
the first 1 or 2 drops and wipe the tip clean.
• Close the control solution bottle tightly and store at a
temperature between 46–86 ˚F (8–30 ˚C).
You may do a control solution test:
• When you want to practice the test procedure using the
control solution instead of blood,
• When using the meter for the first time,
• Whenever you open a new box of test strips,
• If the meter or test strips do not function properly,

22 www.i-sens.com www.i-sens.com 23
Control Solution Testing
Step 3
Shake the KetoSens Control
Solution bottle well before each test.
Remove the cap and squeeze the
bottle to discard the first drop.
Then wipe the tip with a clean
tissue or cloth. Dispense a drop
of control solution onto a clean
non-absorbent surface. It helps to
squeeze a drop onto the top of the cap as shown. After the
symbol appears on the display, apply the solution to the
narrow edge of the test strip until the meter beeps. Make
sure the confirmation window fills completely.
Step 1
Insert a test strip into the meter’s test strip
port, with the contact bars facing upwards.
Gently push the test strip into the port until
the meter beeps. Do not force the test strip
into the meter.
The symbol will show up.
Step 2
Press and hold the ▶button for 3 seconds till the
symbol appears on the display.
• If your symptoms are inconsistent with the blood β-Ketone
test results and you feel that the meter or test strips are not
working properly,
• If you drop or damage the meter.
Note:
The KetoSens Control Solution can be purchased separately.
Contact Customer Service: 1-800-429-5001 Mon–Sat,
9 am–9 pm EST.
Caution:
The range printed on the test strip box is for the KetoSens
Control Solution only. It has nothing to do with your blood
β-Ketone level.
Step 4
A test result will appear after the meter
counts down from 8 to 1.
The result is stored in the meter’s memory
but it is not included in the averages.
Step 5
Compare the result displayed on the
meter to the KetoSens Control Solution
range printed on the test strip box.
The result should fall within that range.
Used strips should be discarded safely in
appropriate containers.
Note: The meter may switch off if the control solution is
not applied within 2 minutes of the symbol appearing
on the screen. If the meter turns off, remove the strip,
reinsert, and start from step 2.
Control Solution Range
Control A: 1.9–2.9 mmol/L
Control B: 3.4–5.4 mmol/L

24 www.i-sens.com www.i-sens.com 25
Comparing the Control Solution Test Results
The test result of each control solution should be within the
range printed on the label of the test strip box. Repeat the
control solution test if the test result falls outside of this range.
Out of range results may occur in the following situations:
If results continue to fall outside the range printed on the test
strip box, the KetoSens Test Strip and Meter may not be
working properly. Do not use your system and contact Customer
Service: 1-800-429-5001 (9 am–9 pm EST, Monday–Saturday).
At all other times, contact your healthcare professional.
Situations
• When the control solution bottle was
not shaken well,
• When the meter, test strip, or the
control solution were exposed to
high or low temperatures,
• When the first drop of the control
solution was not discarded or the tip
of the bottle was not wiped clean,
• When the meter is not functioning
properly.
• When the control solution is past the
expiration date printed on the bottle,
• When the control solution is past its
discard date (the date the bottle was
opened plus three (3) months),
• When the control solution is
contaminated.
Actions
Repeat the
control solution
test by referring
to the 'Notes'
on page 21.
Discard the
used control
solution
and repeat the
test using a
new bottle of
control solution.
Caution: To reduce the chance of infection
• All components that come into contact with blood
samples should be considered to be biohazards capable
of transmitting viral diseases, even after disinfection.

Caring for Your System
• To minimize the risk of transmission of blood-borne
pathogens, the pre-cleaning and disinfection procedure
should be performed as recommended in the instructions
below.
• Wash your hands thoroughly with soap and water after
handling the meter, lancing device, or test strips.
• If the meter is being operated by a second person who
is providing testing assistance to the user, the meter and
lancing device should be disinfected prior to use by the
second person.
Pre-cleaning and Disinfection:
Pre-cleaning procedure is needed to clean dirt as well as
blood and other body fluids on the exterior of the meter and
lancing device before performing the disinfection procedure.
The disinfection procedure is needed to prevent
transmission of blood-borne pathogens.
• For the meter and lancing device, this pre-cleaning and
disinfection procedure should be performed once per
week.
Note: The life span of a KetoSens meter is 5 years. We
recommend cleaning and disinfecting both the meter and
lancing device at least once per week. We have validated
a total of 260 cleaning and disinfecting cycles (260
Cleaning and 260 disinfection cycles) to represent weekly
cleaning and disinfecting over the use life of your meter
and lancing device.
1 pre-cleaning and 1 disinfection cycles per week * 52
weeks per year * 5 years = 260 pre-cleaning and 260
disinfection cycles
