You may think you can't live without your cell phone or handheld computer. But if you have diabetes, a blood glucose meter is truly the one gadget your life depends on.
What is a blood glucose meter?
A blood glucose meter is a device that measures the amount of glucose in your blood. It is a portable, battery-powered tool that calculates your glucose level quickly - usually in less than a minute.
Most require you to prick your skin with a skin-pricking device called a lancet and place a droplet of blood onto a test strip. The test strip is inserted into the glucose meter and the meter measures your blood sugar level. Your blood glucose reading will then appear on the screen of the meter.
It's important to purchase a good meter, use it correctly, and check your blood sugar as often as your doctor directs. Keep a record of your blood sugar levels. This will help you and your doctor see if your diabetes treatment plan is working.
1. How to use the meter correctly
To use your meter, follow these steps:
Wash your hands and dry them well. Also wash the skin surface where you will do the testing.
Get your glucose meter ready. Each meter works differently, so make sure you follow the directions carefully to get accurate results. Practice with your doctor or diabetes educator before you bring the meter home.
Find out where on your body you can use your meter. Some only work on the fingertip. Others allow you to test on other places as well, such as the hand, arm or thigh.
Prepare your lancet. Again, each type is different so read the directions and practice before you use it.
Place the lancet on your skin and push the button. Do not prick the same place each time. When using the fingers, aim for the side of the fingertip, not the top. The side is usually less sensitive and does not bruise as easily.
Place the top of blood on the test strip.
Follow the rest of the instructions that come with your meter.
When the blood glucose result appears, record it in your log or journal.
