Many meters don't need a code from the test strips, but some will. If your meter does, make sure the code number on the bottle of test strips matches the number on your meter. If the numbers don't match, follow the directions that come with your meter for changing the code number.

Wait for the results. Most meters take only a few seconds to give you the results. It's important to record your blood sugar results and when you tested it. It's also helpful to note when you last had something to eat. Your doctor will use your record to see how often your blood sugar levels are in your target range.

Record the results

You and your doctor will use your blood sugar testing record to see how often your levels are in your target range. Here are some ideas for how to do it.

• Get printed blood sugar logs.

  You can get these logs from companies that make diabetic medicines and supplies. Or use a home blood sugar diary.

• Make a blood sugar log in a notebook.

  You can record other information in the log or notebook, such as insulin doses, your exercise, and foods you have eaten. You and your doctor will find this information most useful when looking for patterns and reasons for your blood sugar levels.

• Try using the memory storage feature of your meter and other note-taking features.

  Find out if your doctor can transfer the data to your medical record or if you can make reports to share.

Prevent sore fingers

Frequent blood sugar testing can lead to sore fingertips. Here are some ideas to help avoid this.

• Always prick the side of the fingertip.

  Don't prick the tip of the finger. If you do, the prick will be more painful, and you may not get enough blood to do the test accurately.

• Don't squeeze the fingertip.

  If you have trouble getting a drop of blood large enough to cover the test area of the strip, hang the hand down below the waist. Count to 5. Then squeeze the finger starting close to the hand and moving outward to the end of the finger.

• Use a different finger each time.

  Set a pattern for which finger you stick so that you won't use some fingers more than others. If a finger gets sore, don't use it for testing for a few days.

• Try a different device.

  Some blood sugar meters need only a very small amount of blood.

• Use a different lancet.

  Some lancet devices can be set to prick the skin deeply or lightly depending on the thickness of the skin and where on the body you are getting the blood.

• Don't reuse lancets.

  Lancets get dull and can cause pain. Plus, a used lancet can carry bacteria that could make you sick. Some people reuse lancets anyway. If you do, be extra careful with handwashing each time. And use a new lancet each day to reduce the chance for bacteria growth.
