Follow these steps to obtain a drop of blood from your finger.
CAUTION: It is important that you use the correct technique and a 21
gauge lancet to obtain the right type and amount of blood sample. Failure
to do so may cause inaccurate results. If you use another type of lancing
device or lancet, make sure to follow the instructions that came with that
device to get the correct blood sample.
1. Prepare sampling supplies
• Lancet device
• Sterile blood lancet
• Alcohol pad
2. Increase blood flow in your fingers by:
• Warming your hand (wash in warm water or use a heating pad/hand warmer)
• Gently massaging your finger
• Holding your hand below your heart
3. Identify a site on your fingertip to puncture
Choose:
• a middle finger on either hand
• an area near the top of the finger to either side
of center
• an area away from any calluses or scars
4. Clean the puncture site
Clean the selected area with 70% isopropyl alcohol, or an
alcohol solution. Dry thoroughly with gauze.
5. Puncture your fingertip
Follow the instructions that came with the Lancet device to
puncture the fingertip.
• Gauze
• Sharps or other puncture resistant
container
6. Apply pressure to your fingertip
Apply gentle, continuous pressure until a large, hanging drop of
blood (at least 15 µL) forms.
Apply the hanging drop of blood to the sample well on the test strip
See Performing a Test (Section 8) for complete instructions.
7. Clean and dry the puncture area after
applying the sample
Hold gauze over the puncture site until the bleeding stops.
8. Dispose of all used materials into a sharps or other puncture proof
container
NOTE: Used test strips, gauze, alcohol pads, lancing device and lancets may be considered
biohazardous waste in your area. Be sure to follow your local regulations for proper disposal.

10. Reviewing Past Results in the Monitor Memory

Follow these steps to review past results that are stored in the monitor memory.
Whenever you successfully perform a test, the result is automatically stored in the monitor
memory along with the date and time of the test. You can review your previous results and
share them with your health care provider. The monitor memory will store up to 120 results in
the order in which the tests were taken, beginning with your most recent result. The latest 60
results are available for on-screen review.
The monitor memory also stores PT computation errors, errors that occur when not enough
blood has been applied to the test strip, and QC errors.
You may access the monitor memory after performing a test, or whenever your monitor is
turned on. Simply press the Memory button
( ) will appear on the display as you review past results.
