What A1C means and why it’s important

A1C can help track the progress of your diabetes treatment plan

Your healthcare professional may have told you that your A1C level is not where it should be and given you an A1C goal that you’ll be working towards. But what is A1C and why is it an important part of treatment?

An A1C test measures your blood sugar level average over time

A1C gives a picture of your blood sugar levels over a few months

Your A1C test:

  • Gives you and your healthcare professional an overall picture of your blood sugar level over the past 2 to 3 months
  • Is not like your daily test, which shows you how much glucose, or sugar, you have in your blood at one given moment
  • Can also help you and your healthcare professional decide if your overall treatment plan needs adjustment

How Toujeo® may help lower your A1C

Toujeo® has proven 24-hour blood sugar control. By taking Toujeo® each day as your doctor directs, you may be better able to keep your blood sugar levels within your target range. After 3 months, this has been shown to result in lower A1C levels for people just like you.

Talk to your doctor about what to do if you have low blood sugar (hypoglycemia).

Toujeo® should not be taken if you have low blood sugar or if you are allergic to any of the ingredients in Toujeo®.

How Toujeo® and other insulins work in your body

When you eat, your body breaks the food into its basic components. One of them is glucose (sugar). Glucose travels through your bloodstream and enters the body cells to provide energy. For glucose to get into the cells, it needs insulin. Insulin is the key that unlocks cells for glucose to enter and deliver energy.

With diabetes, the body cannot produce insulin or can’t use the insulin it produces. This means glucose can’t get into the cells and remains in your bloodstream. This raises your A1C level over time.

Insulin, including long-acting insulins like Toujeo®, allows glucose to enter the cells and be converted to energy, helping reduce the buildup of glucose in your blood cells, thereby lowering blood sugar and A1C levels.

What is a normal A1C range? What is the A1C range for a person with diabetes?

  • An A1C level for someone who doesn’t have diabetes is normally under 5.7% 
  • If you have diabetes, your A1C level may be 6.5% or higher
  • However, the American Diabetes Association (ADA) recommends that an A1C level of less than 7% is a reasonable goal for many nonpregnant adults with diabetes

Your doctor may set a different goal for you.

The chart below shows examples of A1C values that your doctor may tell you, and how that result compares to the numbers that you may see on your blood sugar monitor. Because these values are averaged over a period of time, they are called estimated average blood sugar or eAG.

aGoals are for many nonpregnant adults with diabetes. Target A1C levels will be individualized by your healthcare professional.

Checking your A1C

  • If you are meeting your treatment goals, your healthcare professional may recommend you check your A1C at least 2 times a year
  • If you are not meeting your A1C goal, your healthcare professional may recommend you check your A1C once every 3 months
  • Talk to your doctor about your recommended goals and how often you should have your A1C checked
