Controlling your blood sugar is very important part of managing diabetes. Regularly testing your blood sugar helps measure the effectiveness of your meal plan, physical activity and medications is by testing your blood sugar regularly.
To self-test your blood sugar, you need a blood glucose meter, a test strip and a lancing device. Then, follow these steps:1
Follow the instructions included with your lancing device to get a drop of blood— which normally include shaking your hands below the wrist or gently squeezing your finger a few times to help. While testing from the tip of a finger is most common, it is possible to use alternate site testing (AST). Other methods of testing and monitoring look at your blood sugar in the long-term. An HbA1c (also known as glycated hemoglobin or A1c) test gives you a picture of your average blood glucose control for the past 2 to 3 months.
Dr. Madani instructs his patients on general diabetes education.
The long-term measure of blood sugar control, also known as A1C or glycated hemoglobin. (On this site, we use A1C.) The A1C test measures how many A1C hemoglobin cells (a specific part of red blood cells) have sugar attached to them. Because these cells live for about four months, this gives a picture of how well blood sugar has been controlled for the past few months. The American Diabetes Association recommends an A1C result of 7% or less to help reduce the risk of long-term complications of diabetes.1

The HbA1c test (also known as A1c or glycated hemoglobin) measures your average blood sugar levels over a period of time by taking a sample of a specific component of your red blood cells—hemoglobin A1C molecules.
Some blood sugar naturally attaches itself to these A1C molecules as the molecules move through your bloodstream. When this happens, the molecule is considered "glycated." The more sugar in your blood, the more glycated A1C molecules you will have.1
The A1C test is not a substitute for frequent self-monitoring. It shows the average amount of blood sugar in the body over the last 3–4 months. Frequent highs and lows can result in a healthy-looking A1C result. Only self-monitoring can show how meals, physical activity, medications and stress affect your blood sugar over short periods of time. This provides more reference as you manage your diabetes.
Most experts recommend an HbA1c test every 3 months. Your healthcare professional will help you schedule HbA1c tests and decide what testing schedule is right for you.
