Why Use a Blood Glucose Monitor?

Blood glucose monitoring plays an important role in diabetes control. Uncontrolled blood sugar can cause expensive complications in term of money and health. A long-term study showed that keeping blood glucose levels close to normal can reduce the risk of diabetes complications by up to 60%.

A blood glucose meter is the best way to track the effects of your meals, food choices and exercise on your blood glucose levels. When you are sick or stressed, before and after sleeping, if dehydrated, and before driving are other times you may need to track your glucose. By tracking your levels you can quickly take action to bring your blood sugar levels within range if needed. Your doctor will also use your blood glucose meter results to alter your treatment regimen, if needed. However, blood glucose meter results are not used to diagnose diabetes.

How Do Test Strips Work?

The OneTouch brand of meters measure the glucose content of a blood sample by means of an electrical current produced in the test strip. Glucose in the blood sample mixes with special chemicals in the test strip and a small electric current is produced and measured by the meter. The strength of this current calculates your blood glucose level.

Test results are "plasma-calibrated" (instead of whole-blood results), common with most meters. The results you receive from your doctor are also from the plasma. This makes it easier for patients and caregivers to compare meter results with laboratory tests. The meter measures the current, calculates your blood glucose level, displays the result, and stores it in memory.

Test results with the OneTouch Blood Glucose Monitoring System are presented in milligrams/deciliter (mg/dL). Normal ranges for blood glucose in an adult is 80 to 120 mg/dL before a meal and less than 180 mg/dL after a meal. After your glucose result appears, the meter will also display a Range Indicator Arrow below your glucose result to indicate if your result is below, above or within your range limits. If your readings are high or low, this may require immediate treatment according to your healthcare professional's recommendations.

Before Using the OneTouch Meter

  • Review the specific OneTouch Blood Glucose Monitoring System Owner’s Manual for all instructions on meter set-up and use, test strip and control solution use, battery information and care.
  • A review of meter display messages, what they mean, and what action you should take is also included in the Owner’s Manual.
  • The blood glucose monitoring system is intended to be used by a single patient and should not be shared.
  • Be sure to keep the owners manual in a safe spot for easy and quick reference. Contact OneTouch Customer Care at 1-800-227-8862 for further questions.

Use no other test strips or control solution other than specific OneTouch brand recommended for use with your meter.

Control Solutions are used to check that the blood glucose meter and test strips are working together properly and that the test is performing correctly. If required, you should perform a control solution test:

  • Whenever you open a new vial of test strips.
  • If you suspect that the meter or test strips are not working properly.
  • If you have had repeated unexpected blood glucose results.
  • If you drop or damage the meter.
  • To practice the test process instead of using blood.
  • Once a week.

What are Code Numbers?

Code numbers are used to calibrate your meter with the test strips you are using to obtain accurate blood sugar results. If required with your meter, you must code the meter before using it for the first time and then every time you change to another vial of test strips.

Codes are required with the OneTouch UltraMini and the OneTouch Ultra 2. The OneTouch Verio, Verio IQ, and Verio Flex meter do not require coding. See your owners manual to determine if you must code your meter.

OneTouch Meter Comparison

The OneTouch system is intended for use outside the body (in-vitro diagnostic use). It should be used only for testing fresh capillary whole blood samples for glucose (sugar). It should not be used for the diagnosis of diabetes or for testing in newborns.

Before using any product to test your blood glucose, read all instructions and practice the test.
Do all quality control checks as directed and consult with a diabetes health care professional if you have an error.

Patients can upload their data and view a personalized home page designed to help get them more involved in their own care. They can download their glucose monitoring reports before doctor appointments for discussion.

  • OneTouch Reveal draws a timeline of blood sugar events, highlighting when you have been repeatedly out of your target range.
  • Creates a visual snapshot that connects your blood sugar with food, insulin, and activity.
  • See and share your progress with your doctor, family, or caregivers.
  • Most OneTouch meters can be connected to a computer via a USB to download your blood-glucose data to the OneTouch Reveal web app or other compatible software.
  • The OneTouch Verio Flex meter is wireless and can be connected via Bluetooth.
  • The OneTouch Reveal mobile app is listed as one of the top 10 most downloaded diabetes management apps globally.

Do You Need Help With the Cost of Your Diabetes Supplies?

OneTouch diabetes supplies can be found at most retail pharmacies. Test strips and control solutions are sold separately and are not typically supplied in your blood glucose meter kit.

OneTouch may be able to help you make diabetes supplies more affordable. OneTouch products are always covered by Medicare Part B and patients pay $0 with most supplemental health insurance. OneTouch supplies can also be ordered from various mail order houses. Visit the OneTouch website at or call their customer service at 1-800-227-8862.

Glossary and Important Information

Dehydration: Severe dehydration resulting from excessive water loss may cause false low results. If you believe you are suffering from severe dehydration, consult a healthcare professional immediately.

Low glucose results: If your test result is lower than 70 mg/dL, it may mean hypoglycemia (low blood glucose). This may require immediate treatment according to your healthcare professional's recommendations. Although this result could be due to a test error, it is safer to treat first, and then repeat the test. Temperatures lower than 43 to 50 degrees F may result in inaccurate test results. Retest in a warmer environment.

High glucose results: If your test result is greater than 180 mg/dL, it may mean hyperglycemia (high blood glucose). If you do not have symptoms, first repeat the test. Your healthcare professional can work with you to decide what actions, if any, you should take if you continue to get results higher than 180 mg/dL or if you have symptoms.

If your blood glucose is higher than 600 mg/dL, you may have extreme severe hyperglycemia (high blood sugar). Retest your blood glucose. If the result is over 600 mg/dL, contact your healthcare provider immediately for instructions.

Repeated unexpected results: If you continue to get unexpected results, check your system with control solution. Review your manual section on control solution testing for specific directions.

If you are experiencing symptoms that are not consistent with your blood glucose results and you have followed all instructions in this booklet, call your healthcare professional. Never ignore symptoms or make significant changes to your diabetes control program without speaking to your healthcare professional.

Hematocrit: A hematocrit (percentage of your blood that is red blood cells) that is either very high (above 55-60%) or very low (below 20-30%) can cause false results.

Comparing laboratory and meter results: Both OneTouch Meter test results and laboratory test results are both expressed in plasma-equivalent units. However, meter results may differ from laboratory results due to normal variation. The OneTouch Meter glucose value should agree within +/-20 percent under normal conditions, and that variation is considered accurate.

However, results can vary more than +/- 20 percent in some situations. Blood glucose levels can change quickly over short periods of time due to meals, exercise, hematocrit levels, dehydration, medications, environmental temperature or stress.

It is best to fast for eight hours before doing comparison tests. Check with your healthcare provider prior to fasting. See the OneTouch Test Strip Package insert for important information on guidelines for making an accurate comparison between meter and laboratory results.

To make an accurate comparison between meter and laboratory results, follow the guidelines described in the specific OneTouch Blood Glucose Monitoring System Owner’s Manual.

WARNING: Keep the meter and testing supplies away from small children. The battery door, test strips, lancets, protective disks, and control solution cap are choking hazards.
