Your result

Have you already been told you have diabetes?

Right now, are you very thirsty, vomiting, drowsy, confused or breathing fast?

Your answer appears here.

Choose the test, enter the result from your report, and you will see the range it falls in.

Who it is for

Adults aged 18 and over who are not pregnant. A diagnosis of diabetes needs a doctor and a repeat test.

How it works

Fasting blood sugar: under 100 mg/dL is normal, 100 to 125 is the prediabetes range, 126 or more is the diabetes range. Two hours after a meal or a glucose drink: under 140 is normal, 140 to 199 is prediabetes, 200 or more is diabetes. HbA1c: under 5.7% is normal, 5.7 to 6.4% is prediabetes, 6.5% or more is diabetes.

A doctor repeats a test before diagnosing diabetes. Below 70 mg/dL is low and needs treating; 300 mg/dL or more needs a doctor the same day. mmol/L results are converted by multiplying by 18.

A tool cannot know your history and does not replace a doctor who has examined you. If you are worried, or the result surprises you, talk to a doctor.
