There are various tests that can be undertaken to diagnose diabetes. The most common ones are:

Urine Sugar Test:: When blood levels of glucose are very high, some of the glucose may show up in the urine, indicating a diabetic condition

Urine Ketone Test: Ketones (beta-hydroxybutyric acid, acetoacetic acid, and acetone) are the end-product of rapid or excessive fatty-acid breakdown. Fatty-acid release from adipose tissue (body fat) is stimulated by a number of hormones including glucagon. Increased levels may, therefore, indicate diabetes.

Oral Glucose Tolerance Test: This is a measure of the body’s ability to use glucose. It is commonly used to test for gestational diabetes. The test involves drinking a sweet liquid containing glucose. A blood sample is collected one hour later to test the blood glucose level.

Blood Glucose Test: This measures the amount of glucose in the blood. Results are usually available within 1-2 hours.
