How can diabetes be diagnosed?

In brief: Diagnosis of Diabetes

Type 1 diabetes
• Type 1 diabetes can be picked-up with a blood test to measure the level of glucose in the blood.
It may be necessary to fast for eight hours before the blood sample is taken

Type 2 diabetes
• You may be asked to have a blood test to measure the level of glucose in your blood. This might be a fasting glucose test, which is taken after you haven't eaten for at least eight hours, or a Glycosylated hemoglobin ( HbA1c) test done at any time
• If your doctor can't make a definite diagnosis after these tests, you may have a glucose tolerance test. This measures how your blood glucose level changes over time after you swallow a sugary drink. You will need to fast overnight before having this test

Diabetes in Pregnancy
Gestational diabetes can be diagnosed using a glucose tolerance test, which is carried out in the morning, after you have eaten nothing overnight. Your doctor will give you a solution of glucose to drink and take blood samples at different intervals to see how your body deals with the glucose over time
• If you're at risk of developing diabetes in pregnancy, you will be offered a glucose tolerance test by your doctor or midwife between 24 and 28 weeks. If you have had gestational diabetes before, you will be offered a test at 18 weeks, and another one at between 24 and 28 weeks if the first is normal
