  4. Wash your hands under warm water for 30-60 seconds.

  5. Twist off the blue tab to break the seal of the lancet.

    1. DO NOT touch the white tip.

  9. Press down firmly until you hear a click.

  10. Gently press the pricked finger from below the puncture site to allow a large drop of blood to form.

    1. AVOID strong repetitive pressure on the pricked finger. This may cause contamination of the sample

  11. Wipe away the first drop of blood with the gauze.

  12. Hold the finger downward to allow the blood to drop onto the collection card circles.

    1. DO NOT touch the card with your finger.

    2. DO NOT rub or smear the sample.

    1. Filling more than the required number of spots is recommended (if possible) to ensure enough sample is present.

    2. If you have more than one test or a test measuring many analytes, you may need to fill spots on two cards. Consult your requisition form to determine if this applies to you.
