Tests and Diagnosis

The American Diabetes Association (ADA) suggests that anybody with a body mass index of over 25 regardless of age must undergo a screening test for diabetes. It is also recommended for anyone above the age of 45. Some of the common tests done for the diagnosis of the disease are as follows:

Glycated Hemoglobin (A1C) Test: This test shows that average blood sugar levels from the past two to three months. If the A1C levels are not consistent or if you have some conditions where it can make your A1C test inaccurate like pregnancy then your doctor may ask you to go for the other tests.

Random Blood Sugar: A blood sample will be taken at a random time. A reading of 11.1 millimoles per liter (mmol/L) or higher is regarded as diabetes.

Fasting Blood Sugar: A blood sample will be taken after an overnight fast. A fasting blood sugar level between 100 and 125 mg/dL (5.6 and 6.9 mmol/L) is considered prediabetes. If it’s 126 mg/dL (7 mmol/L) or higher on two separate tests, you’ll be diagnosed with diabetes.

Body Mass Index: If your body mass index (BMI) before pregnancy was 30 or higher or if you have any of your relative with diabetes then your doctor may test you for diabetes.
