Type 2 Diabetes Diagnosis
Type 2 diabetes is a disorder in which the sugar that we intake through food accumulates in our blood instead of being used as a fuel for energy. A high blood sugar level is harmful to various internal organs. Therefore, it’s important to diagnose diabetes before it gets any worse. There are several types of blood sugar tests available for type 2 diabetes diagnosis.
These are-
- HbA1c Test
- Fasting Blood Sugar Test
- Random Blood Sugar Test
- Postprandial Blood Sugar Test
- HbA1c Test
Glycated haemoglobin or A1c test is the most accurate test used for the diagnosis of diabetes. As it calculates the amount of glucose or sugar attached to our haemoglobin. Haemoglobin is a protein found in the RBCs of our blood.it is accurate and most suggested because it checks the amount of glucose present in our blood from the last 2-3 months. This test makes it easier to detect the upcoming complications caused due to high blood sugar.
The value of A1c comes in percentage. So, if your A1c value is 6.5 or greater then you may have diabetes.

Fasting Blood Sugar Test
Another way of diagnosing diabetes is by fasting blood sugar tests. This test is performed on an empty stomach. The patient has to do fasting for 8-10hours to get the best result from this test. It is advised to get this test performed in the morning before breakfast.
The results of these tests are interpreted as-
- If your fasting blood sugar is less than 100mg/dl then it’s normal.
- If it comes between 100-125mg/dl then you have prediabetes or high chances of developing diabetes in the future.
- 125 mg/dl or more than that fasting blood sugar means you have diabetes.
-
Random Blood Sugar Test
Random blood sugar tests can be done anytime according to the convenience of the doctor and patient. And this test is available in most laboratories. This sugar test is usually performed when patients already have the symptoms of diabetes.
- More than 200 mg/dl or random blood sugar value is considered diabetes.
- Below 140mg/dl is normal
- Between 140- 199mg/dl is considered prediabetes.
-
Oral Glucose Tolerance Test
The oral glucose test is less performed because it is inconvenient in comparison to other tests. For the glucose tolerance test, you will have to fast overnight, which means you can’t eat or drink anything. Then your doctor will inject out some blood from your body to check your fasting blood sugar. After this, you will be given a glucose solution to drink. Then after 2 hours, your blood sugar level will be tested again.
This procedure helps in diagnosing how well your body is handling glucose. This test is suitable for diagnosing gestational diabetes.

Postprandial Blood Sugar Test
Postprandial is a glucose test performed to check diabetes. This test is usually used as a regular screening test for diabetic patients. In this test sugar level is checked before eating usually in the morning then after 2 hours of eating the meal to recheck how well your body is handling the sugar. This test helps already diabetic patients to find out what is working for them and what is not. Pp value of more than 200mg/dl may be diabetes.
