How to use your blood glucose meter

Here are some tips to help you get accurate readings:

Talk with your health-care provider

Compare the meter's result with your doctor's lab result to make sure you're using the right technique and that the meter works properly. Your doctor should tell you how often to check your blood sugar.

Follow directions

Not all blood glucose meters are the same, so check the manufacturer's directions for proper use and cleaning. Store your unit and test strips at room temperature in a clean, dry place.

Use the right test strips

If you use ones made for other models, you might get inaccurate results. So use only those designed for your meter. Read the strip inserts to see if you have any medical conditions that could interfere with testing accuracy. Test strips should not be left exposed to the air for more than a few minutes before testing. Keep the vial closed tightly, and be aware of the expiration date.

Test from your fingertip if you think your glucose is low

Some machines allow you to test blood from other sites, such as the forearm, but those aren't as accurate when your blood glucose levels are changing rapidly.

Wash your hands with soap and warm water and towel dry vigorously

Even a little sugar on your skin from food can throw off your results, as can dirt. The warm water and the brisk action of drying increases blood flow to your fingertips. Snapping your fingers can help as well.

Brace your finger

Holding it against a solid surface makes it less likely you'll pull away as the needle strikes.

Don't squeeze your finger

That usually leads to a poor finger prick and can result in errors.
