Step 8
Obtain a blood sample using the
lancing device. Place the device
against the pad of the finger. The best
puncture sites are on the middle or
ring fingers. Press the release button.
Remove the device from the finger.
Wait a few seconds for a blood drop to
form. A minimum volume of 0.5 microliter is needed to fill the
confirmation window.
Step 9
After the
symbol appears on the screen, apply the blood
sample to the narrow end of the test strip until the meter
beeps. If the blood sample does not fill the confirmation
window completely, an Er4 message may appear because of
abnormal viscosity or insufficient volume. If an Er4 message
appears, retest with a new test strip.
