One Touch Blood Glucose Monitors
One Touch is a brand of small portable blood glucose monitoring systems that can be used by patients with diabetes. Brands examples include One Touch Ultra 2, One Touch UltraMini, One Touch Select and One Touch Verio IQ systems. The systems consist of the meter, lancing device, a lancet and a carrying case. Test strips and control solutions are sold separately. Each meter offers different features, such as size of screen, memory, and result displays.
One Touch Ping is a remote blood glucose monitoring system and insulin pump that work together. Refer to the specific manufacturer users guide for all information pertaining to the One Touch Ping.
LifeScan has discontinued the manufacturing the One Touch Ultra and One Touch UltraSmart Meters, effective December 31, 2012. This action was taken due to a shift in demand from these product and not the result of any safety issues.
How do they work?
The One Touch brand of meters measure the glucose content of a blood sample by means of an electrical current produced in the test strip and measured by the meter. Test results are "plasma-calibrated". This makes it easier for patients and caregivers to compare meter results with laboratory tests.
Blood glucose monitoring plays an important role in diabetes control. A long-term study showed that keeping blood glucose levels close to normal can reduce the risk of diabetes complications by up to 60%.
Test results with the One Touch Blood Glucose Monitoring System are presented in milligrams/deciliter (mg/dL), ranging from 20 to 600 mg/dL. If the glucose measurement “mg/dL” unit does not appear when results are displayed, or for other questions regarding the One Touch Blood Glucose Monitoring Systems call your healthcare provider or Lifescan Customer Service at 1 800 227-8862.
Review the specific One Touch 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.
Before Using the One Touch Meter
If you have been using another type of meter - one that provides whole-blood results - you may notice that your test results with the One Touch system are about 12% higher.
Use no other test strips or control solution other than specific One Touch brand recommended for use with your meter.
The One Touch 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 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. These recommendations apply to all blood glucose monitoring systems and are supported by the American Association of Diabetes Educators, the American Diabetes Association, the U.S. Food and Drug Administration, and the Advanced Medical Technology Association.
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 severe hyperglycemia. 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 One Touch 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 One Touch 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 One Touch 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 One Touch 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.
Important Test Strip Information
- Store test strip vials in a cool, dry place below 86F (30C). Keep away from direct sunlight and heat. Do Not refrigerate.
- Store test strips in their original vial only. To avoid damage or contamination, Do Not transfer test strips to any other place.
- After removing a test strip from the vial, replace the vial cap immediately and close it tightly.

- Write the discard date (3 months after first opening the vial) on the vial label when you first open it. Discard remaining One Touch Test Strips after the discard date. Do Not use test strips beyond the expiration (printed on package) or discard date, whichever comes first, because they may cause inaccurate results.
- Avoid getting dirt, food or liquids on the test strip. With clean, dry hands, you may touch the test strip anywhere on its surface.

- One Touch Test Strips are for single use only. Never reuse a test strip that has had either blood or control solution applied to it.
- Apply only One Touch Control Solution or a blood sample to the test strip.
- If you’re using a OneTouch UltraMini or OneTouch® Ultra 2 Meter, be sure to get OneTouch Ultra Blue Test Strips—the only test strips that will work with your meter.
- In the U.S., you can find OneTouch Test Strips at pharmacies where diabetes products are sold.
- Refer to additional information in the One Touch Test Strip package.
WARNING: Do Not swallow test strips. The test strip vial may contain drying agents that are harmful if inhaled or swallowed and may cause skin or eye irritation.
