Blood Glucose Monitors

If you have diabetes, it's extremely important to keep track of your blood sugar level to avoid conditions like hypoglycemia (low blood sugar).

How do blood glucose monitors work?

The most common blood glucose monitors use test strips to measure glucose levels. With these types of monitors, you insert a test strip into the device and prick your fingertip with a type of needle called a lancet to draw a drop of blood. When you apply the blood to the test strip, the device will display your blood glucose level.

What can cause my blood glucose level to change?

Luckily, modern blood glucose monitors make it easy to keep track of your blood glucose level, and many monitors include total, pre-meal and post-meal test averaging for all the data you need. Some can even make provide test results on your smartphone using a complementary app so you don't have to use paper logbooks. Look for a blood glucose monitor that's easy to use, comfortable and that fits your budget.
