How should we check blood sugar?

1. Wash hands with soap and water. Do not use hand sanitizer or wet wipes. 
2. Remove cover from the poker and put the lancet in.   Twist off the top of the new lancet.  Put the cover back on.
3. Prepare the poker for use.  Each one is different.
4. Put the test strip in the meter, with the testing side out.  This turns the meter on. 
5. Hold the poker against the side of the finger tip.  Do not put it against the fingernail.  Press the button to poke the skin.  Set the poker aside.  
6. Hold or press the finger firmly just below the first finger joint to get a drop of blood.  If the blood doesn’t come out, let the hand hang down until fingertip is pink.
7. Touch a drop of blood to the test strip.
8. Press cotton ball or tissue on poke site to stop bleeding.
9. Read the blood sugar number on the glucometer.  Write this number in the log book. 
10. If it is time to change the lancet, take it out of the poker.  Put it in the red sharps box.  Throw the used test strip into the garbage.
