• An abnormally high or low red blood cell count (hematocrit level over 65 % or
below 15 %) may produce inaccurate results.
• If your test result is below 3.3 mmol/L or above 13.3 mmol/L, consult a
healthcare professional immediately.
• Inaccurate results may occur in severely hypotensive individuals or patients
in shock. Inaccurate low results may occur for individuals experiencing
a hyperglycemic hyperosmolar state, with or without ketosis. Critically ill
patients should not be tested with blood glucose meters.
• Inaccurate results may occur in patients undergoing oxygen therapy.

15 Checking the System
You may check your meter and test strips using the CareSens S
Glucose Control Solution (control A and/or B). The CareSens S
Control Solution contains a known amount of glucose and is used
to check that the meter and the test strips are working properly.
The test strip vials have CareSens S Control Solution ranges printed
on their labels. Compare the result displayed on the meter to the
CareSens S Control Solution range printed on the test strip vial.
Before using a new meter or a new vial of test strips, you may
conduct a control solution test following the procedure on pages
17–19.
Note
• Use only the CareSens S 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 20–25 °C.
• Before using the control solution, shake the bottle, discard the first few
drops and wipe the tip clean.
• Close the control solution bottle tightly and store at a temperature between
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 vial of test strips,
• If the meter or test strips do not function properly,
• If your symptoms are inconsistent with the blood glucose test results and you
feel that the meter or test strips are not working properly,
• If you drop or damage the meter.
Control Solution Testing
Step 1
Inserting Test Strip
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. Be careful not to bend the strip while pushing
it in.
The
symbol will be displayed on the screen.
Step 2
Activating Control Solution Test Mode
You can flag the control solution test result by pressing
and holding the
▶
button for
3 seconds. To undo the control solution flag, press and
hold the
▶
button for 3 seconds again.
Step 3
Applying Control Solution to Test Strip
Shake the bottle 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 tip of the test strip until the
meter beeps. Make sure the confirmation window fills
completely.
Note
The meter may switch off if the control solution sample 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 1.
Step 4
Waiting for the Result
The display segments will rotate clockwise and a test result will appear after the
meter counts down from 6 to 1.
When flagged, the result is stored in the meter’s memory but it is not included
in the averages.

• Glucose in blood samples reacts with the chemical in the test strip to produce
a small electrical current. The CareSens S Fit BT meter detects this electrical
current and measures the amount of glucose in the blood sample.
