Once your doctor has gone through your symptoms, and overall health history, they may ask you to take a test for diabetes if they suspect any risk. You have to go through the following tests:
Fasting blood sugar test
This test is usually done after an 8-hour fast. An ideal blood sugar level should be between 100 mg per dL to 125 mg per dL. If anything, more comes in the test result, it indicates diabetes.Oral glucose tolerance test
A patient has to drink a beverage containing 75 grams of glucose dissolved in water. If after 2 hours, a blood sugar level of 200 mg/dL or higher indicates diabetes.Random blood sugar test
This test measures glucose level in your blood at any time of day. If the level of blood glucose is 200 mg/dL or higher indicates diabetes.A1C blood test
This test which is calculated in percentage provides information about a person’s average levels of blood glucose over the previous 3 months. Below 5.7% is considered as a normal A1C level. A result between 5.7% and 6.4% indicates prediabetes and over 6.4% indicates diabetes.
