What Does a Fasting Glucose Test Measure?

A fasting glucose test is similar to the meaning behind HbA1C blood tests, which is to help provide a clear diagnosis for diabetes; although fasting glucose tests measure blood sugar levels over a much shorter period of time than HbA1C test measurements.

Fasting glucose tests are taken by measuring your blood sugar levels after you haven’t eaten or drank anything (other than water), for at least 8 hours.

The results from the fasting glucose test can help your practitioner gain a clearer insight into your current blood sugar levels, in order to provide an effective management plan for you. You can calculate results from fasting glucose tests by using this range:

• Less than 6.0 mmol/L = normal
• 6.1 to 6.9 mmol/L = prediabetic
• 7.0 mmol/L and above = diabetic

Anything above 7.0 mmol/L is considered high blood sugar levels and could lead to you receiving a diagnosis for diabetes.
