Precision Xtra Blood Glucose Test Strips provide you the flexibility to test on your forearm, upper arm or base of thumb.
Why test on a site other than your finger?
Other parts of the body have fewer nerve endings per square inch than the finger. This can make alternate site testing less painful. Of patients who tested using alternate sites, seven out of ten say it is the same or less pain than testing on the finger.2
What do I need to get started?
Testing on the arm requires a special lancing device with a clear cap. Contact Customer Care for more information.
Are there guidelines for testing on a site other than your finger?
There may be times when alternate site results are different from fingertip results. This happens when glucose levels are changing rapidly. Do not test on your arm or base of thumb when:
- You think your blood sugar is low.
- You have been diagnosed with hypoglycemic unawareness.
- The results do not match the way you feel.
- Within two hours of eating a meal, taking insulin or exercising
For more information on testing on the arm and base of thumb, please call Customer Care at (888) 522-5226.
