Dear Advocate™ TD-4223 A/B System Owner:
You have chosen one of the best blood glucose monitoring systems. This manual contains important information you must know about the system. Please read it thoroughly and carefully.
The greatest feature of this system is its
function (with a talking symbol speaking
on the meter), which is an acoustic aid for users especially with visual disability. Please note that this function is optional. If the meter does not have , it will not provide speaking function.
Another unique feature is its internal established code.
Not only does it simplify the glucose test, it also provides you and your doctor with more precise and accurate test results.
The system is intended for use outside the body (in vitro diagnostic use). It should be used only for testing glucose (sugar) and only with fresh capillary whole blood samples. The system is intended for use in the home and in clinical settings. It should not be used for the diagnosis of diabetes or the testing of newborns.
PLEASE NOTE
Before using any product to test your blood glucose, read all instructions thoroughly and practice the test. Do all quality control checks as directed and consult with a diabetes healthcare professional. These recommendations apply to all blood glucose monitoring systems and are supported by the Diabetes Educator
Section of the Canadian Diabetes Association.

IMPORTANT INFORMATION
Severe dehydration and excessive water loss may cause false low results. If you believe you are suffering from severe dehydration, consult a healthcare professional immediately. blood glucose (hypoglycemia). Test results greater than 2 240 mg/dL* ( 13.3 mmol/L) mean high blood glucose (hyperglycemia). If you get results below
60 mg/dL or above 240 mg/dL, and do not have symptoms, first repeat the test. If you have symptoms or continue to get results that fall below 60 mg/dL or above 40 mg/dL, follow the treatment advice of your healthcare professional.
Apply only capillary whole blood sample to the absorbent hole. Applying other substances to the absorbent hole will cause inaccurate results.
If you are experiencing symptoms that are not consistent with your blood glucose test results and you have followed all instructions described in this owner’s manual, call your healthcare professional.
4
A red blood cell count (hematocrit) that is very high
(above 60%) or very low (below 20%) can cause false results.
The following WILL NOT affect results:
Elevated blood triglyceride, reducing substances such as uric acid and ascorbic acid when occurring in expected blood concentration, or acetaminophen, dopa, methyldopa, L-dopa and tolbutamide occurring in expected blood concentrations.

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 fingertips to check their blood glucose levels. This system provides you to test thigh with the equivalent results to fingertip testing.
What’s the advantage?
Fingertips feel pain more readily
because they are full of nerve endings (receptors). At other body sites, since nerve endings were not so condensed, you will not feel as much pain as at the fingertip.
When to use AST?
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 events, take blood samples from your finger only.
6
We strongly recommend you do AST ONLY in the fol lowing intervals:
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 exercise.
Do NOT use AST if:
You think your blood glucose is low.
If you are awareness of being hypoglycemia.
Your AST results do not match the way you feel.
You are testing for hyperglycemia.
Your routine glucose results are often fluctuating.
If you are pregnant.
How to increase the accuracy?
Stimulating blood perfusion by rubbing the puncture site prior to blood extraction has a significant influence on the glucose value obtained. Blood from the site without rubbing exhibits a measurably different glucose concen tration than blood from the finger. When the puncture site was rubbed prior to blood extraction, the difference was significantly reduced.
If you would like to obtain blood from sites other than the finger, replace the lancet device cap with the clear cap. The clear cap for AST is an optional accessory, please contact your local customer service.
NOTE: We suggest that before getting a drop of blood rub the pucture site about 20 seconds before penetration.

INTRODUCTION OF THE SYSTEM
Intended Use
The system is intended for use outside the body (in vitro diagnostic use). It should be used only for testing glucose (sugar) and only with fresh capillary whole blood samples. The system is intended for use in the home and in clinical settings. It should not be used for the diagnosis of diabetes or for the testing of newborns.
Principle of Measurement
The test is based on the measurement of electrical current generated 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.
8
Contents of the System
The system should be used with three main products: the blood glucose meter, test strips, and a control solution. These products have been designed, tested, and proven to work together as a system to produce accurate blood glucose test results. Use only the Advocate

and the lancet device.
29
Testing Procedure
Wash and dry your hands first before starting.
STEP 1. Set the Lancing Device
Screw off the cap of Lancing Device.
Insert a lancet into the lancet holder and push down firmly until it is fully seated.
Twist the protective disk until it separates from the lancet.
Replace the lancet device cap. Turn the cap until it is snug but not too tight.
The adjustable tip offers 5 levels of skin penetration. Twist the adjustable tip in either direction until the number lines up with the Arrow:
1-2 for soft or thin skin
3 for average skin
4-5 for thick or calloused skin
30
Slide the ejection/cocking control back until it clicks. If it does not click the device may have been cocked when the lancet was inserted.
Blood from sites other than the fingertip
A clear cap makes it easier to get a drop of blood for AST.
When you want to obtain blood from sites other than the finger, replace the lancet device cap with the clear cap. Turn the clear cap until it is snug but not too tight, and then slide the ejection/ cocking control back until it clicks.
Note: The clear cap is an optional accessory, please contact your local customer service
The lancing device is now ready. Set aside for later use.

COMPARING METER AND LABORATORY RESULTS
Test results from the meter and laboratory are both expressed in plasma-equivalent units. However, 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.
(See test strip package insert for typical accuracy and precision data, and for important information on limitations.) To make an accurate comparison between meter and laboratory results, follow the guide-lines below.
Before you go to the lab:
Perform a control solution test to make sure that the meter is working properly.
It is best to fast for at least eight hours before doing comparison tests.
Take your meter with you to the lab.
While at the lab:
Make sure that the samples for both tests (the meter test and the lab test are taken and tested within 5 minutes of each other).
Wash your hands before obtaining a blood sample.
Never use your meter with blood that has been collected in a gray-top test tube.
Use fresh capillary blood only.
37
You may still have a variation from the result because blood glucose levels can change significantly over short periods, especially if you have recently eaten, addition, if you have eaten recently, the blood glucose level from a finger stick can be up to 70 mg/dL( 3.9 mmol/L) higher than blood drawn from a vein (venous
Therefore, it is best to fast for eight hours before doing comparison tests. Factors such as the amount of red blood cells in the blood (a high or low hematocrit) or the loss of body fluid (severe dehydration) may also cause a meter result to be different from a laboratory result.
