How do you know if you have diabetes? Your doctor or occupational health professional can test you for the presence of diabetes using a urine and/or blood test.
Diabetes may be detected in a routine urine test where excess glucose is present. A blood test that measures the level of glucose in the blood will confirm whether or not the underlying cause could be diabetes. Finally a ‘glucose tolerance test’ is performed where serial blood sugar levels are measured following a fixed dose of a sugary drink. This test is used because a person with diabetes is unable to clear the blood sugar as quickly as a normal person.
