What are normal blood glucose and HbA1c levels?

What is a normal blood glucose?

Normal blood glucose = 4-6 mmol/L – and less than 8 mmol/L, two hours after a meal.

Blood glucose in prediabetes and diabetes

• Prediabetes is diagnosed if your random blood glucose = 7-11 mmol/L
• Diabetes is diagnosed if you have a random blood glucose > 11 mmol/L (or a fasting blood glucose > 7 mmol/L)

What is a normal HbA1c (haemoglobin A1c)?

Whilst targets can vary slightly based on age and existing health conditions, doctors generally use the following numbers for adults.

Normal HbA1c = 20-41 mmol/mol (or 4-6%).

• HbA1c is your average blood glucose (sugar) levels for the last three months

HbA1c in prediabetes and diabetes

• Prediabetes is diagnosed if your HbA1c = 42-47 mmol/mol (6-6.5%)
• Diabetes is diagnosed if your HbA1c > 47 mmol/mol or over (>6.5%)

What are HbA1c target levels?

• If you’re at risk of developing type 2 diabetes, your target HbA1c level should be below 42mmol/mol (6%)
• If you have diabetes, an ideal HbA1c level is 48 mmol/mol (6.5%) or below.
