Blood Sugar Testing
What kind of blood glucose monitor?
There are a wide variety of blood glucose monitors to choose from, from stripped down single-reading meters to models with computer compatibility, alarms, and backlights. Think about the functions that are important to you. For example, if you like seeing trend data on your glucose readings, a blood glucose monitor that has extensive memory may be for you. People with vision impairment may prefer a large display, or an adaptive meter with voice reading capabilities. Size may also matter; if you prefer an unobtrusive blood glucose monitor that can be used discreetly you’ll want something small and easy to handle. Your certified diabetes educator or pharmacist is a good source of information on what blood glucose monitor may be right for you.
Most meters on the market today read blood plasma, the same standard that is used in a clinical setting (many older meters provide whole blood readings). Consider the following features when deciding on a blood glucose monitor:
- Size and user-friendliness. Is it convenient for your needs and easy-to-use?
- Time to readout. How long does the meter take to display results?
- Memory. How many test results will the meter’s memory hold, and does it have the capability of averaging results for a designated time period?
- Trend data and computer compatibility. Does the meter interface with a computer and allow you to download meter results and generate blood sugar trend information?
- Battery life and availability. Will battery power last a reasonable amount of time, and are the batteries easily available at a local store or must they be special ordered?
- Blood sample size. Does the meter require a minimal amount of blood?
- Alternative site testing. Some meters allow you to test blood samples from the forearm and other sites beyond the fingertips.
- Cost. Factor in the cost of test strips when evaluating your meter purchase.
- Multitasking. Some blood glucose monitors double as blood ketone testers (Precision Xtra; Abbott Diabetes Care).
- Adaptive technology. If you have vision impairments, you may need a meter that “speaks” your results.
- Bells and whistles. Glow-in-the-dark cases, backlighting, and swappable faceplates are just a few of the other features today’s blood glucose meters can offer.
