What to look for when selecting a meter

International Standard ISO 15197: 2003 recommends the minimum acceptable accuracy for results produced by a glucose monitoring system as follows:
- 95% of the individual glucose result shall fall within ±15mg/dl of the results of the manufacturer's measurement procedure at glucose concentration of < 75mg/dl and within ± 20% at glucose concentrations ≥ 75mg/dl.

The accuracy of the test results also depends on interference with other sugars. Choose a blood glucose meter that employs the glucose specific testing methods, such as glucose oxidase. Glucose oxidase chemistry is very stable and specific. It does not react with other sugars, such as maltose in the blood. This means that it only measures glucose in the blood, and not other sugars. The entire line of OneTouch® blood glucose monitoring systems utilise only glucose oxidase testing methods.

Testing speed
For the most convenience, get a blood glucose meter that can perform tests in a flash. Some meters get you results in as quickly as 5 seconds.

Amount of blood needed
Most blood glucose meters only require a drop of blood for test strips. The OneTouch® Meters require a drop of blood (1.0 -1.5 microliter) for easy testing. All OneTouch® Test Strips have a visual confirmation that makes it easy to see when there's blood enough for an accurate reading.

Easy to read and use
The best meters are easy to use, and have big clear display boxes for easy reading. When picking a meter, have the diabetes educator help you go through the steps of usage, reading, recording, storage and cleaning.

Whole Blood Glucose vs. Plasma Glucose9
"Glucose levels in plasma (one of the components of blood) are generally 10-15% higher than glucose measurements in whole blood (and even more after eating). This is important because home blood glucose meters measure the glucose in whole blood while most lab tests measure the glucose in plasma. However, there are many meters on the market now that give results as plasma equivalent. These meters that give plasma equivalent readings have a built-in algorithm that translates the whole blood measurement to make it seem like the result that would be obtained on a plasma sample. This allows patients to easily compare their glucose measurements in a lab test and at home. It is important for you and your health care provider to know whether your meter gives its results as whole blood equivalent or plasma equivalent as your lab results may have a greater difference vs. your meter as a result. The entire line of OneTouch® blood glucose monitoring systems report readings in plasma glucose.

Size of needle
Most blood glucose meters come with lancing devices that have tiny replaceable lancets for pricking fingertips. These lancing devices allow you to adjust the depth of penetration for the least discomfort when testing.

Alert on Counterfeit Test Strips
LifeScan, Inc., a division of Johnson & Johnson, has discovered incidents of counterfeit OneTouch® Test Strips in various countries around the world. Counterfeit product is fake product not made by LifeScan, Inc. Use of these counterfeit test strips could result in inaccurate test results that may lead to improper treatment.

If you determine you have counterfeit test strips, you should immediately discontinue their use and replace them. You should also contact your physician to assess potential treatment implications and report your discovery immediately to LifeScan, Inc.
