To prepare the Unistik lancet, twist the pink cap 3-4 times to remove. Do not pull the cap out as that will trigger the lancet. Position the lancet tip against the rounded side edge of your finger and then press down. This will activate the needle.
If the Unistik lancet does not produce enough blood, try the larger BD lancet. To prepare the BD lancet, remove the cap from the lancet and activate it by pushing it against your finger firmly.
