8 Things to Consider When Choosing a Blood Glucose Monitor
Test strips are sold separately from glucose monitors and can be pricey.(KRISTEN AFONSO/PRISCILLA DE CASTRO)Blood glucose monitors are devicesabout the size of a cell phone or smallerthat are used to monitor your blood sugar at home.
Although they can be mistaken for the latest fancy digital device, these gadgets come with lancets, which are used to poke the finger, and test strips, which is where you place the drop of blood before inserting it into the monitor to get a blood-sugar reading.
They range in price from $20 to $70, but are often given away for free by various health-care providers. Companies can afford to give the monitors away for free because they make their money from the glucose strips, which can be pricey$1 or more per strip. If you check your blood sugar as often as you should, you can easily spend more than $100 a month.
The vast majority of your cost will come from glucose strips. So when choosing your device, you should pay attention to the cost of the strips, even if the monitor is free.

You may need to select a specific blood glucose monitor because that's what your insurance plan covers. Edith Sciamanna, 79, of Binghamton, N.Y. has the Accu-Chek Advantage for just that reason. "I'm quite satisfied with it," she says.
However, if you do have the luxury of choice, there are differences between models that can help you decide (in addition to the cost of the strips). Consider that some systems:
- Are multisite: This means you can prick yourself not only on the finger but also on the upper arm, forearm, thigh, calf, or fleshy part of the hand.
- Require smaller samples of blood: The lancet doesn't poke the skin as deeply.
- Give results in as little as five seconds: This feature is particularly handy if you think you're experiencing hypoglycemia. If blood sugar is dangerously low, you need to find out fast and consume glucose to counteract it.
- Have more memory: Some record as few as 10 previous tests; others can keep a record of the 500 previous tests.
- Are smaller and more portable than others: If you're not into big purses, your blood sugar monitor's size might matter. Good newstoday's units are much smaller than in the past. Models like the FreeStyle Lite and the OneTouch UltraMini fit into a slim pocket.
- Come with software: Although most glucose monitors can store results in their memory, some devices will also sync with your computer. Downloading your data may make it easier to share your readings with your physician and track your blood sugars over many months. You'll also be able to back up your data in the event you lose your monitor. If you're computer-challenged or prefer to keep track of your readings manually, you can skip this feature.
- Are geared towards those with low vision: Larger readouts make it easier for people with vision problems to see the results.
- Are easier to use: Because you may not always be checking your blood sugar under ideal conditions, it's important to consider the design of the model and its strips. Some models feed their strips from an internal drum (Accu-Chek Compact Plus) or disc (Ascensia Breeze 2); others have to be inserted into a small slot, a challenge at 4 a.m. when your blood sugar is low and your hands are shaking.
