Top 4 Tips for Finger Pricks

Checking your blood sugars often is an important part of your diabetes care. You may find yourself wanting to check more often, but hesitate because your fingers are sore or bruised. Here are our top tips to help bruised fingertips heal faster and prevent bruising in the first place!

  1. Use Soap and Water

When it’s time to check your blood sugar levels, start by washing your hands with soap and warm water, then let your arm dangle by your side for a minute. This promotes blood to flow to your fingertips, making testing easier. While you’re doing this, rub the spot you’re planning to test with your finger to encourage even more blood flow.

Although alcohol does sanitize your hands, it’s better to use mild soap and water. Alcohol can dry out your skin, especially when it’s used often, making testing more difficult.

2. Use a Fresh Lancet

It’s tempting to re-use a lancet, but a dull lancet can lead to more bruising and pain.

To prevent this, use a new lancet each time. New lancets are sharper, less traumatic to use, and less likely to bruise your fingers. Carry extra lancets with you so you don’t run out.

3. Test the Sides of Your Fingers—And Change Sites Often

The tips of your fingers are covered in nerve endings. Good for things like typing, bad for blood glucose testing. To avoid hitting those sensitive areas, test the sides of your fingers.

Using the sides of your fingers also doubles the sites you can use. Since you can test on both sides of each finger, it will be longer between tests at each site. More time to heal means less bruising.

4. Apply Pressure

Once you’re done testing, apply pressure to stop the blood flow. Hold a cotton ball or tissue on the site for 30 seconds. At the same time, hold your hand up higher than your heart. If you’re still bleeding, put on a small bandage.

With these guidelines, you can heal your fingers bruised from glucose testing more quickly and be on your way to managing your diabetes like a pro.
