Note ◙: If the fingertip color is not changing, then warm the
fingers carefully by running them under warm water or
rubbing them vigorously. Remember to dry them
completely or your results may be unreliable.

Always use new unused materials (such as lancet,
gauze, etc.).

If you are being helped when getting a test sample, your
helper should wash their hands with soap and warm
water. They should also put on gloves before doing the
fingerstick.

Use a 21g 1.8 mm depth single-use auto-disabling
lancet. Smaller gauge/shallow depth lancets (i.e.
diabetes 23g lancets) should not be used. Refer to the
Lancet device instructions for more information on use.

Lance the fleshy part of the fingertip just slightly left or
right of the center. Press lancet firmly against finger.

Refer to the package inserts for the Lancet device for
more information.
The best test sample is when:

The blood is collected right after the fingerstick and put
into the test strip sample well without delay. If the blood
is not collected or tested quickly (within 15 seconds),
repeat with a fresh fingerstick and a new strip.

There are no bubbles or air pockets in the tube or
sample.
