Tips for Getting Better Blood Flow
When pricking your finger with a lancet, following are a few easy things you can do to ensure you draw enough blood. Everyone is different and testing is a skill. Finding your best testing sweet spots may take some trial and error.
- When you prep your lancet device, adjust the depth selector.Have your meter ready to test, check your setting of the depth selector; there are six settings for adjusting the depth of the lancet device to accommodate everything from soft or thin skin too thick or calloused skin. With experience, you'll find the optimal depth for your skin. Before testing, make sure your lancet device is set to your optimal setting. If you find that the lancet is painful for you, it’s possible that your lancet is set to hit too deep. Adjust the lancet depth.
- Warm your hands. Testing when your hands are cold can result in lesser blood flow. To heat up your fingers, sit on them briefly, rub them together, or give them a good scrub using warm water and soap.
- Test on the side of your finger. You'll get better blood flow than if you prick it in the middle.
- Grip the finger you are going to test with your index finger and thumb of your other hand and squeeze for about 12 seconds before using the lancet. This increases hydrostatic pressure.
- After puncturing your finger, put the lancing device aside and wait for a blood drop to form, about 4 seconds. Do not squeeze the finger; lowering your hand to hip height and massaging the finger softly may improve the blood flow. If you still have too little blood, gently squeeze your hand, starting at the part closest to your palm and working your way down your finger until you have enough
- Switch fingers regularly when testing. Using the same spot on the same finger can lead to calluses.
