Testing Your Blood
The following steps will show 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 Voice
Blood Glucose Monitoring System requires a very small
drop of blood which 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. Then dry your hands and the
test site thoroughly. Make sure there is no alcohol, soap, cream 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.
