The following steps will show you how to use the meter, test strips, lancing device
and sterile lancets together to measure your blood glucose level.
Step 1 – Getting a Drop of Blood
The On Call
Extra Mobile Blood Glucose Monitoring System requires a very small
®
drop of blood. The blood may be obtained from the fingertip, palm (at base of the
thumb) or forearm. Before testing, choose a clean, dry work surface. Familiarize
yourself with the procedure and make sure you have all the items needed to obtain
a drop of blood.
IMPORTANT: Prior to testing, wipe the test site with an alcohol swab or soapy water.
Use warm water to increase blood flow if necessary. Dry your hands and the test
site thoroughly. Make sure there is no alcohol, soap or lotion on the test site.

Fingertip Testing
For fingertip sampling, adjust the depth penetration to reduce the discomfort. You
do not need the clear cap for fingertip sampling.
1. Unscrew the lancing device cover from the body of the lancing device. Insert a
sterile lancet into the lancet holder and push it until the lancet comes to a
complete stop in the lancing device.
