How is Diabetes diagnosed?

Diabetes is typically diagnosed through a combination of blood tests that measure blood sugar levels. The most common tests used to diagnose diabetes include:

  1. Fasting blood sugar (FBS) test: A blood test that measures blood sugar levels after an overnight fast. A fasting blood sugar level of 126 mg/dL or higher on two separate occasions is considered diagnostic of diabetes.
  2. Oral glucose tolerance test (OGTT): A blood test that measures blood sugar levels after a person has fasted overnight, then again 2 hours after drinking a sugar-containing beverage. A 2-hour blood sugar level of 200 mg/dL or higher is considered diagnostic of diabetes.
  3. A1C test: This test measures the average blood sugar level over the past 2-3 months. It is expressed as a percentage and an A1C of 6.5% or higher is considered diagnostic of diabetes.
  1. Random blood sugar test: A blood test that measures blood sugar levels at any time of the day, regardless of when the last meal was consumed
  2. It is important to note that a single abnormal test result does not necessarily indicate diabetes. A healthcare professional may repeat the test on a different day or use a different test to confirm the diagnosis.

It's important to consult a healthcare professional if you have any symptoms of diabetes or if you are at high risk for diabetes. Early diagnosis and treatment of diabetes can help prevent or delay the onset of diabetes-related complications.
