Measuring blood glucose, also known as Glycemic Self-Monitoring (GAS), is a method of checking the amount of glucose (sugar) in the blood, using a blood glucose meter – anywhere, anytime. ASG is used when it is likely to lead to a change in therapy; it must be systematic and multi-day in type 1 diabetes and limited to certain patients in type 2 diabetes. It requires education with a health professional. For more information, talk to your healthcare professional or medical team.

Here you will learn some basic principles about:

  • Glycemic targets (or targets) for adults
  • The way your doctor analyzes your blood parameters
  • The importance of self-monitoring
  • When to measure and what to look for
  • How to share the results with your doctor

Glycemic targets for non-pregnant men and women

The glycemic goal must be set by your doctor, it must be individualized according to each profile and can evolve over time. Talk to your doctor.

How your doctor analyzes your blood – the HbA1c test

Your doctor uses what is known as an HbA1c test (Glycosylated Hemoglobin or Glycosylated Hemoglobin) to see how much your blood glucose has averaged over the last two to three months. Used for type 1 and type 2 diabetes, it tells you and your doctor how well you are responding to your treatment and whether any adjustments are needed. The goal is to keep your blood sugar below seven percent (7%). 1 The HbA1c test is sometimes referred to as Hb A1c test, HbA1c test, or glycated hemoglobin test.

The importance of self-monitoring

The result of your HbA1c test will not show the daily effects of your food choices and your physical activity. The glucose meter is a way to observe and track the immediate effects of your food choices and your physical activity on your blood glucose. This allows you to take immediate action to bring your blood glucose back to the target range if necessary. Your doctor will also rely on the results of your meter to evaluate and adjust your treatment.
