■The system is intended for use outside the body (in vitro
diagnostic use). It is for single-patient use. It should be used only
for testing glucose (sugar) and only with fresh capillary whole
blood samples taken from the finger and the alternative sites
including the palm, the forearm.The system is intended for use
at home. It should not be used for the diagnosis of diabetes or
for the testing of newborns.
■The System is to be used by a single person and should not be
shared.
■The System is intended for self-testing outside the body (in vitro
diagnostic use) by people with diabetes at home as an aid to
monitor the effectiveness of diabetes control. The System should
not be used for the diagnosis of or screening for diabetes, nor for
neonatal use. Alternative site testing should be done only during
steady–state times (when glucose is not changing rapidly).
■The “
Easy Trak II ” Test Strips are for use with the Easy Trak II
Meter to quantitatively measure glucose in fresh capillary
whole blood samples drawn from the fingertips, palm and
forearm.
■The control solutions is intended for use with Easy Trak II
System, to check that the glucose meter and test strips are
working properly and that you are doing the test correctly. These
solutions contain a known range of glucose, as indicated on the
strips vial bottles.
1. Open the battery cover on the back of meter.

AST in this system can be used only during steady-state blood
glucose conditions described in the section of “About AST”.
Test principle
The test is based on the measurement of electrical current gen-
erated by the reaction of glucose with the reagent of the strip. The
meter measures the current and displays the corresponding blood
glucose level. The strength of the current produced by the reaction
depends on the amount of glucose in the blood sample.
ABOUT ALTERNATIVE SITE TESTING (AST)
Important: There are limitations for doing AST.
Please consult your healthcare professional before you do AST.
What is AST ?
Alternative site testing (AST)
means that people use parts of the
body other than the fingertips to
check their blood glucose levels.
This system allows you to test on
the palm, the forearm with the
equivalent results to fingertips
testing.
Fingertips feel pain more readily because they are full of nerve
endings (receptors). At other body sites, since nerve endings are
not so condensed, you will not feel as much pain as at the fingertip.
Food , medication , illness, stress and exercise can affect blood
glucose levels. Capillary blood at fingertip reflects these changes
faster than capillary blood at other sites. Therefore when testing
blood glucose during or immediately after meal, physical exercise,
or any other event, take a blood sample from your finger only.
You do AST in the following instances:
● In a pre-meal or fasting state (more than 2 hours since the
last meal).
● Two hours or more after taking insulin.
● Two hours or more after exercising.
■ Alternative site testing(AST) should not be used to calibrate
continuous glucose monitoring systems (CGMs).
■ Results from alternative site testing should not be used in
insulin doses calculations.
● You think your blood glucose is low.
● You are unaware of hypoglycemia.
● You are testing for hyperglycemia.
● Your AST results do not match the way you feel.
● Your routine glucose results are often fluctuating.

If your lancing device differs from the one shown here, please
refer to the manufacturer’s manual to ensure proper usage.
To reduce the chance of infection:
● Never share a lancet or the lancing device.
● Always use a new, sterile lancet. Lancets are for single use
only.
● Avoid getting hand lotion, oils, dirt, or debris when handling
the lancets.
Stimulating blood perfusion by rubbing the puncture site prior to
blood extraction has a significant influence on the glucose value
obtained. Blood from a site that has not been rubbed exhibits a
measurably different glucose concentration than blood from the
finger. When the puncture site was rubbed prior to blood
extraction, the difference was significantly reduced.
On the lancets and the lancing device.
Please follow the suggestions below before obtaining a drop
of blood:
● Rub the puncture site for about 20 seconds before penetration.
● Select the puncture site either at the fingertips or another
body part (please see section “Alternative Site Testing”
(AST) on how to select the appropriate sites).
● Clean the puncture site using cotton moistened with 75%
alcohol and let it air dry.

Please work with your doctor to determine a target range that
works best for you.
The meter provides you with plasma-equivalent results. The
result you obtain from your meter may differ somewhat from your
laboratory result due to normal variation. Meter results can be
affected by factors and conditions that do not affect laboratory
results in the same way. To make an accurate comparison
between meter and laboratory results, follow the guidelines below.
Before going to the lab:
■ Do a control solution test to make sure that the meter is
working properly.
■ Fast for at least eight hours and then do comparison tests,
if possible.
■ Take your meter with you to the lab.
While staying at the lab:
Make sure that the samples for both tests test are taken and
tested within 15 minutes of each other.
■ Wash your hands and then obtain a blood sample
■ Never use your meter with blood that has been collected in
a gray top test tube.
■ Use fresh capillary blood only.

CONTROL SOLUTION TEST
Material needed:
● Glucose Meter
● Test strips
● TaiDoc Control solution
When to do a control solution test:
◆ When you suspect that the meter or test strips are not
working properly.
◆ If your blood glucose test results are not consistent with
how you feel.
◆ After the test strips are exposed to extreme conditions.
◆ After dropping the meter.
The control solution is to check that the meter and the test
strips can work together as a system and work correctly.
Step 1
Insert the test strip to turn on the meter. Insert the test strip into
the meter. Wait for the meter to display the drop symbol.
Step 2
You may press “M” button to select CTL mode, for
selecting the CTL mode, please refer to the “THE
TWO MEASURING MODES” section.
Step 3
Apply the control solution
Shake the control solution vial thoroughly before use.
Squeeze out a drop and wipe it off, then squeeze another drop
and place it on the tip of the vial cap.
Hold the meter to move the absorbent hole of test strip so it
touches the drop. Once the confirmation window fills completely,
the meter will begin counting down.
To avoid contaminating the control solution, do not directly
apply control solution onto a strip.
The result of the control solutions test appears on the display.
The result will not be stored under CTL mode.
The result of the control solutions test should be within the range
printed on the test strip vial label. If the test results falls outside
the specified range printed on test strip vial label, repeat the test.
Results falling outside the specified range may be caused by:
■ Error in performing the test
■ Expired or contaminated Control Solution
■ Expired or contaminated Test Strip
■ Malfunction of your Meter
If you continue to get control solution test results that fall outside
of the range printed on the vial, the system may not be working
properly, Do not use the meter. Please contact your customer
support immediately
