Which screening is use to test for diabetes

Answer: The most common screenings used to test for diabetes include the following:

1. Fasting Plasma Glucose (FPG) Test: This test measures blood glucose levels after an individual has not eaten (fasted) for at least 8 hours. It is often conducted in the morning. A result of 126 mg/dL or higher on two separate occasions usually indicates diabetes.

2. Oral Glucose Tolerance Test (OGTT): This test also begins with a fasting blood glucose measurement. Then, the individual drinks a sugary solution, and blood glucose levels are tested several times over the next two to three hours. A blood glucose level more than 200 mg/dL after two hours indicates diabetes.

3. Hemoglobin A1c (HbA1c or A1C) Test: This blood test shows your average level of blood glucose over the past 2 to 3 months. An A1C level of 6.5% or higher on two separate occasions indicates diabetes.

4. Random Plasma Glucose Test: This test measures blood glucose at any time of the day regardless of when the person last ate. A blood glucose level of 200 mg/dL or higher suggests diabetes, particularly if the individual also has symptoms of high blood sugar, such as increased thirst, urination, and fatigue.
