There are several types of glucose meters on the market but all perform the same function. They report the approximate level of blood sugar by sampling a small drop of blood on specially coated paper. By pricking the finger tip (or, in some cases, other specific parts of the body), a droplet can be collected on a disposable test strip which the meter can then analyze and display the results. Diabetics use glucometers to monitor their blood sugar, so that they can take preventive steps to avoid both hyperglycemia (high blood sugar) or hypoglycemia (low blood sugar).
Sometimes it's mistakenly believed that people with type 2 diabetes do not need to use a glucometer, so long as they're eating healthy and exercising - but that's just not true. Every diabetic needs to monitor their blood sugar levels for proper self-care.
Here are the main features you should consider before selecting a unit:
Note that there are some units that will not allow you to clear your readings from the unit.
This basic information for glucometers will hopefully give you a starting point to help you decide on a unit that's right for you. Ask if your doctor has samples that you may view or try. Your doctor can also advise you how often you need to check your blood glucose as a important part of your diabetes treatment plan. All glucose meters basically report the same information (although they have different features), so select one that will fit within your budget and your preferences.
