INTRODUCTION TO THE SYSTEM ABOUT YOUR SYSTEM

Intended Use

• The Glucaric Blood Glucose Monitoring System is comprised of Glucaric Blood Glucose Meter and Glucaric Blood Glucose Test Strips.
• The Glucaric Blood Glucose Monitoring System is intended to be used for the quantitative measurement of glucose (sugar) in fresh capillary whole blood samples drawn from the fingertip. The Glucaric Blood Glucose Monitoring System is intended to be used by a single person and should not be shared. It 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 Glucoracy Blood Glucose Monitoring System should not be used for the diagnosis of or screening for diabetes. The Glucaric Blood Glucose Monitoring System is not for use in neonates.

Warnings

• 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. 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 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. Alternative site testing should be done only during steady
  – state times (when glucose is not changing rapidly).

• The blood glucose test strips are for use with the Blood Glucose Meter to quantitatively measure glucose in fresh capillary whole blood samples drawn from the fingertips.

• This device is not intended for use in healthcare or assisted-use settings such as hospitals, physician’s offices, or long-term care facilities because it has not been determined to be safe and effective for use in these settings, including for routine assisted testing or as part of glycemic control procedures.

• Use of this device on multiple patients may lead to transmission of Human Immunodeficiency Virus (HIV), Hepatitis C Virus (HCV), Hepatitis B Virus (HBV), or other bloodborne pathogens.

• When the following phenomenon happens, the user should stop using meter and contact customer service:
  -The test result of control solution exceeds the range of vial labeled.
  -The meter fails to display relative information;
  -The meter does not respond when inserted test strips;
  -The meter damaged severely (eg. Broken case, screen chalkboard)

Test principle

The System uses electrochemical methodologies. The System quantitatively measures blood glucose levels using an Amperometry method. The method involves detecting the current produced from glucose oxidation. The strength of the current produced by the
reaction depends on the amount of glucose in the blood sample. The electrons generated during this reaction are transferred from the blood to the electrodes. The magnitude of the resultant current is proportional to the concentration of glucose in the specimen.
The current level is converted into a readout displayed on the meter.

Preparing the puncture site

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.
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 at the fingertips.
• Clean the puncture site using cotton moistened with 70% alcohol and let it air dry.

Fingertip testing

Hold the lancing device firmly against the side of your finger. Press the release key.
You will hear a click, indicating that the puncture is complete.

NOTE：

• Choose a different spot each time you test. Repeated punctures at the same spot may cause soreness and calluses.
• It is recommended to discard the first drop of blood as it might contain tissue fluid, which may affect the test result.

Comparing Meter and Laboratory Results
The meter provides you with the measurement result equivalent to whole blood. 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, please follow the guidelines below.

Before going to the lab:

• Do a control solution test to make sure that the meter is working properly.
• If possible, fast for at least eight hours and then do comparison tests.
• Take your meter with you to the lab.

While staying at the lab:
Make sure that the samples for both tests 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
• 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.

How to do a control solution test

Step 1
Insert the test strip into the meter. Wait for the meter to display the drop symbol.
Step 2
You may press “S” button to select CTL mode, for selecting the CTL mode, please refer to the “The two measuring modes” section.

Hold the meter to move the absorbent hole of test strip that made it touch is the drop. Once the confirmation window filled completely, the meter will begin counting down.
To avoid contaminating the control solution, do not directly apply control solution onto a strip.
Step 4
The result of the control solution test appears on the display. The result will not be stored under CTL mode.
The result of the control solution test should be within the range printed on the test strip vial label. If the test result falls outside the specified range printed on test strip vial label, please 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 the range printed on the vial, the system may not be working properly, do not use the meter. Please contact your customer support immediately.

NOTE:

• Do not use the expired control solution.
• Users should periodically review their technique, and compare with the results that obtained from meter and obtained from laboratory method or a well-maintained and monitored system used by healthcare provider.
