Performing a Test in Order
PRECAUTION
- The glucose test results of blood samples taken from different sites might be varied in certain conditions as
your glucose changes rapidly following a drink, a meal, an insulin dose or exercise. In these cases, only the
fingertip test should be used.
- DO NOT test on the palm or forearm if you are testing for hypoglycemia (Low blood glucose).
- Fingertip samples can show the rapid change of glucose faster than palm or forearm samples.
- Consult with your healthcare professionals whenever you want to conduct a sample from palm or forearm.
- As the blood flow taken from forearm is slower than fingertip or palm, we recommend using a special lancing
device with Clear Cap for testing sites other than finger.
- If you use normal lancing device for palm or forearm the blood sample might be not enough for the meter.
- Please periodically compare the test system to a laboratory test system known to be well maintained and
monitored by a healthcare provider.
Performing a Test in Order
Alternative site testing-palm or forearm blood sampling
- To do the alternative site testing, please install the for your Lancing Device.
( For detailed information of lancing device, please check the instruction manual for the Lancing
Device. )
- To increase the blood flow, please massage the puncture area of palm or forearm for a few seconds.
- Immediately after massaging the puncture area, press and hold the lancing device with the against
palm or forearm.
- Then press the release button.
- Continue holding the lancing device against the palm or forearm and gradually increase pressure for a few
