What are normal mmol/L ranges for blood sugar?

Target blood sugar levels for adults are shown below. They will depend on when the blood sugar test was taken in relation to eating. Certain people, such as pregnant women and those with diabetes, may have different target ranges.

The two commonest times to check blood sugar levels are when fasting and two hours after eating. We have normal and optimal ranges for both.

	Fasting		Two hours after eating
	mmol/L	mg/dL	mmol/L	mg/dL
Optimal	≤ 5	≤ 90	≤ 5.6	≤ 100
Normal	≤ 5.6	≤ 100	≤ 7.8	≤ 140

What are HbA1c levels?

HbA1C is a way of assessing the average level of glucose (sugar) in your blood over the past two to three months. The HbA1c test indicates how well blood sugar levels have been controlled over time. This is especially useful for diagnosing and managing diabetes.

The HbA1C test measures the amount of haemoglobin (a protein in red blood cells) with sugar attached to it. The higher your blood sugar levels are, the more glucose attaches to your haemoglobin and the higher your HbA1c will be.

If your HbA1c is elevated, you can lower it through some simple lifestyle changes.

This might include:

Exercise
Changing your diet
Improving your sleep

For more information on HbA1c, read our guide HbA1c - What is it and what is a normal HbA1c range?

Different levels of HbA1c can have different meanings for your health. As a general rule, lower is better. Studies have shown that an HbA1c under 35mmol/mol is associated with lower cancer and heart disease risk. An HbA1c over 39mmol/mol is defined as pre-diabetes by the American Diabetes Association and is associated with a high risk of going on to develop diabetes.

HbA1c (mmol/mol)	HbA1c (%)	Diagnosis
under 20	under 4	Low
30 - 35	5 - 5.4	Optimal
20 - 38	4 - 5.6	Normal
39 - 47	5.7 - 6.4	Pre-diabetes
48 and above	6.5 and above	Diabetes

How can I test for pre-diabetes?

To test for pre-diabetes, we can use either HbA1c, fasting blood sugar or the blood sugar two hours after an oral glucose tolerance test (OGTT).

The HbA1c test gives an average of blood sugar levels over the past two to three months. A result between 39 to 47 mmol/mol (5.7% to 6.4%) indicates pre-diabetes.

The fasting blood sugar test measures the amount of glucose in the blood 8-12 hours since your last meal. A result between 5.6 and 6.9 mmol/L (100 to 125 mg/dL) is called "impaired fasting glucose" and indicates pre-diabetes.

Lastly, a blood sugar level of 7.8 to 11.0 mmol/L (140 to 199 mg/dL) two hours after an oral glucose tolerance test (OGTT) is called "impaired glucose tolerance" and also diagnostic of pre-diabetes.

You can find more detailed information in our guide on testing for pre-diabetes.
