  1. TWIST off the end of the pink/white lancet holder
  2. APPLY lancet hole to the side of a finger and PRESS the device against your finger
    • Pressing with about a 1 lb force will activate the single-use lancet/needle)
  3. APPLY the pointy end of the pipette to the resulting blood
    • (The blood will go into the pipette all by itself)
  4. PLACE pipette in the square hole and PRESS bulb to force the blood out
  5. PUT 7 drops of reagent chemical in the round hole,
